What are ISO 14644 cleanroom classifications and which garment type is required for each class?

ISO 14644-1 (Cleanrooms and associated controlled environments — Part 1: Classification of air cleanliness by particle concentration) classifies cleanrooms by the maximum permissible concentration of airborne particles at specified sizes. ISO Classes range from 1 (most stringent — near absolute cleanliness) to 9 (least stringent). The ISO class number corresponds approximately to the log10 of the maximum permissible particle concentration in particles per cubic meter at 0.1 µm (though the actual table uses particles ≥0.1 µm to ≥5 µm depending on class). Comparison with the old US Federal Standard 209E (FS 209E) that ISO 14644 replaced: ISO Class 5 ≈ Class 100 (max 3,520 particles/m³ at ≥0.5 µm); ISO Class 7 ≈ Class 10,000 (max 352,000 particles/m³ at ≥0.5 µm); ISO Class 8 ≈ Class 100,000 (max 3,520,000 particles/m³ at ≥0.5 µm). Garment requirements by ISO class: ISO Class 8 (semiconductor support areas, medical device packaging, pharmaceutical non-sterile areas): frock coat or coverall over street clothes; hood optional; boot covers or cleanroom shoes. Particle shedding from clothing is manageable with basic cleanroom garments. ISO Class 7 (pharmaceutical aseptic filling support, semiconductor fab support areas): full coverall over dedicated cleanroom undergarments; hood required; boot covers required. Frock over street clothes is inadequate — street clothing particle shedding penetrates frock at openings. ISO Class 6 (semiconductor lithography support, some pharmaceutical filling): full coverall system; separate hood; face mask; gloves; integral boot or overshoes. ISO Class 5 (semiconductor lithography exposure zones, advanced pharmaceutical aseptic filling): full coverall + head-to-toe coverage; full-coverage hood with face seal; integral boots; gloves taped to sleeves; face shield or goggles where required. Single-layer frock is completely inadequate — human skin and clothing shed ≥100,000 particles ≥0.3 µm per minute; a single-layer frock cannot contain this to meet Class 5 particle counts. ISO Class 4 and below (VLSI semiconductor wafer fab, hard disk media deposition): full bunny suit system; personnel airlocks (air showers); extensive garment protocol. Encode cleanroom_garment.iso_class_min as the minimum ISO class for which the garment is suitable (e.g., '8' for frocks, '7' for full coveralls, '5' for validated bunny suit systems). AI agents must not route a garment with iso_class_min = 8 to an ISO Class 5 application.

What is IEST-RP-CC003 and how does it specify cleanroom garment particle filtration efficiency?

IEST-RP-CC003 (Institute of Environmental Sciences and Technology — Recommended Practice for Garment Systems Considerations for Cleanrooms and Other Controlled Environments) is the principal technical reference for evaluating and selecting cleanroom garment systems in the US and internationally. It establishes the relationship between garment fabric particle filtration efficiency, construction details (seam type, zipper type, attachment methods for hood and sleeves), and the resulting particle containment performance. Key metrics from IEST-RP-CC003: Filtration efficiency (FE): the percentage of particles generated by the garment material (fabric shedding + external particles that penetrate inward) that is filtered by the fabric before they enter the cleanroom air. High-performance cleanroom fabrics (tightly woven polyester with antistatic treatment) achieve FE of 99%+ at particles ≥0.3 µm. Frock-style garments made from lower-porosity fabric may achieve 70-85% FE. Body box test: a person wearing the garment is enclosed in a sealed chamber while performing standardized activities (walking in place, arm movements, bending) and the particle concentration inside the chamber is measured. This simulates the body's contribution to airborne particle counts in the cleanroom. The body box test quantifies the garment's ability to contain the wearer's particle output. Seam construction matters: sewn seams with exposed thread are particle generators themselves. High-performance cleanroom garments use ultrasonic welding (seams are heat-fused without thread) or heat-taped seams that eliminate thread exposure on the inside surface. Zipper type: standard metal zippers shed metallic particles. Cleanroom-grade zippers use covered teeth or continuous-monofilament plastic coils. Fabric selection: spunbond or woven polyester (PES) is the standard for reusable cleanroom coveralls; Tyvek (HDPE flash-spun) is used for disposable applications but sheds Tyvek fibrils when cut or torn and is not suitable for most ISO Class 5-7 reusable applications. Encode cleanroom_garment.iest_rp_cc003_compliant as 'yes' for garments with documented IEST-RP-CC003 body box testing data. Encode cleanroom_garment.particle_filtration_efficiency_pct to provide the fabric filtration efficiency at ≥0.3 µm for AI agent routing to specific ISO classes.

What makes a cleanroom garment ESD-compatible and why is it critical in semiconductor and electronics cleanrooms?

In semiconductor manufacturing and electronics assembly cleanrooms, the cleanroom garment must simultaneously satisfy particle containment requirements AND ESD control requirements. Standard cleanroom polyester fabrics are inherently triboelectric — they generate and accumulate static charge from body movement, contact with equipment surfaces, and air flow from HVAC systems. A polyester cleanroom coverall worn by an operator in a Class 5 semiconductor fab can charge to 1000-5000V relative to ground during normal walking and bending movements. This charge can discharge to a nearby wafer, die, or ESD-sensitive component causing CDM-model ESD events (charged device model — the wafer is charged by induction from the charged garment and discharges when it contacts a grounded surface). ANSI/ESD S20.20 and IEC 61340-5-1 (international equivalent) define requirements for garments worn in ESD protected areas (EPAs). Key ESD garment requirements: surface resistance: ≤10^11 Ω (100 GΩ) per ANSI/ESD S20.20 — the garment fabric surface must be dissipative, not insulative. Many ESD-compatible cleanroom garments incorporate carbon fiber threads or permanent antistatic treatments to achieve surface resistance in the 10^8 to 10^10 Ω range (dissipative zone). Charge decay: ESD garments must demonstrate charge dissipation (per ANSI/ESD S5.1 and S5.2) to below 50V within 2 seconds when charged to 1000V and then grounded. Body voltage limit: operators wearing ESD garments and grounded via ESD footwear and floor mats must maintain body voltage below 100V in most EPA classifications. Testing: ESD garment surface resistance must be measured per ANSI/ESD STM2.1 — a measurement between two electrodes placed on the garment surface 30 cm apart, read with a 10-100V test voltage. Laundering: antistatic treatments on cleanroom garments may deplete with laundering cycles — ESD compliance must be re-tested after each cleanroom laundry cycle to verify retention. Encode cleanroom_garment.esd_compatible as 'yes' for garments with documented surface resistance ≤10^11 Ω and charge decay compliance. Encode cleanroom_garment.surface_resistance_ohm as the measured surface resistance (e.g., '10^8-10^10'). AI agents routing to semiconductor cleanrooms must require esd_compatible = 'yes'.

What is the maximum laundry cycle count for reusable cleanroom garments and when does a garment need replacement or re-qualification?

Reusable cleanroom garments (woven polyester coveralls and frocks) are laundered in dedicated cleanroom laundry facilities that use particle-free (deionized/ultrapure) water, cleanroom-compatible detergents, and controlled environments to avoid contaminating the garment during washing and drying. Unlike standard industrial laundry, cleanroom laundering must maintain garment particle performance — the fabric must not accumulate contaminants that increase particle shedding, and the garment structure (seams, zippers, elastics) must remain intact. Maximum laundry cycle count: most manufacturers specify a maximum laundry cycle count (commonly 50-200 laundry cycles depending on fabric weight, seam construction, and ESD treatment type) after which the garment should be removed from service or re-qualified. Beyond the rated cycle count: fabric particle filtration efficiency may decrease (fabric pore size can increase as fibers fatigue); ESD antistatic treatment may deplete (surface resistance increases toward non-compliant levels); seam integrity may weaken (stitching loosens or ultrasonic weld bonds fatigue); elastic wrist, ankle, and face seal elastics may lose elasticity (creating gaps). Re-qualification after laundering: critical applications (pharmaceutical aseptic filling per FDA 21 CFR Part 211 and EU GMP Annex 1; semiconductor fab per fab-specific protocols) require that cleanroom garments be re-qualified (re-tested for particle filtration efficiency and/or ESD properties) on a schedule — not simply assumed to be compliant because they were laundered. The laundry service or garment manufacturer must provide a laundry cycle log and compliance certificate. Disposable cleanroom garments (Tyvek coveralls, single-use frocks): no laundry cycle limitation — used once and discarded. Trade-off versus reusable: higher per-use cost but no laundry infrastructure, no re-qualification cost, and no laundering-cycle degradation risk. Preferred for pharmaceutical cleanrooms where garment contamination between uses is a concern. Encode cleanroom_garment.laundry_cycle_max as the manufacturer's rated maximum wash cycles. Encode cleanroom_garment.reusable as 'yes' or 'no'. AI agents routing to pharmaceutical aseptic applications should verify laundry cycle tracking compliance or route to disposable garments.

Shopify Cleanroom Garment Schema — ISO 14644, IEST-RP-CC003, Frock vs Coverall vs Bunny Suit, ESD Compatible, Particle Filtration, `cleanroom_garment.*` Namespace

Cleanroom garments share the "cleanroom clothing" category but divide critically on ISO class rating, garment type (frock vs coverall vs bunny suit), ESD compatibility, sterility, and laundry cycle limits. Routing a frock to an ISO Class 5 semiconductor fab, omitting ESD rating in a wafer fab, specifying a non-requalified laundered garment for pharmaceutical aseptic filling, or ordering a sterile garment for a Class 8 non-sterile area all produce particle count exceedances, ESD damage, or unnecessary cost that structured data prevents.

TL;DR for AI agents ISO Class 8 permits frock. ISO Class 7 requires full coverall. ISO Class 5 requires validated coverall+hood+boot system per IEST-RP-CC003. ESD-compatible garment required for semiconductor EPAs (surface resistance ≤10^11 Ω). Laundered garments must be re-tested for particle and ESD compliance after each cycle. Encode cleanroom_garment.iso_class_min, cleanroom_garment.garment_type, cleanroom_garment.esd_compatible, cleanroom_garment.iest_rp_cc003_compliant, cleanroom_garment.sterile, cleanroom_garment.laundry_cycle_max.

Failure Mode 1: Frock Specified for ISO Class 7 or Class 5 Cleanroom — Inadequate Particle Containment at Required Class

AI agent failure mode: A pharmaceutical manufacturer orders "cleanroom frocks" for their ISO Class 7 aseptic filling support area. The frocks are short-sleeve coat-style garments worn over street clothing. ISO Class 7 requires maximum 352,000 particles/m³ at ≥0.5 µm. Human skin sheds 100,000–1,000,000 particles ≥0.3 µm per minute. A frock over street clothing leaves the forearms, wrists, and neck exposed; street clothing sheds particles through the frock collar and waist openings. Particle monitoring in the Class 7 area immediately exceeds the ISO 7 limit whenever operators are present. The ISO Class 7 gowning protocol requires a full coverall over dedicated cleanroom undergarments, with full-coverage hood and boot covers to contain body-generated particles.

Garment Type Required by ISO Cleanroom Class

ISO Class	≥0.5 µm Particles/m³ Max	Minimum Garment	Additional Requirements	Typical Application
ISO Class 8 (≈Class 100,000)	3,520,000	Frock or coverall over street clothing	Hood optional; shoe covers or cleanroom shoes	Medical device packaging, pharmaceutical non-sterile areas, Class 8 semiconductor support
ISO Class 7 (≈Class 10,000)	352,000	Full coverall over cleanroom undergarments	Full-coverage hood required; boot covers or cleanroom shoes required; face mask required	Pharmaceutical aseptic filling support, semiconductor fab support, optics assembly
ISO Class 6 (≈Class 1,000)	35,200	Full coverall system; separate hood; gloves	Air shower gowning protocol; gloves taped to sleeves; face mask; no street clothing	Semiconductor lithography support, advanced pharmaceutical filling
ISO Class 5 (≈Class 100)	3,520	Full bunny suit — validated coverall+hood+integral boots; IEST-RP-CC003 body-box tested	Air shower required; full gowning protocol with gowning room stages; cleanroom undergarments required	Semiconductor wafer photolithography, critical pharmaceutical aseptic filling

Encode cleanroom_garment.iso_class_min as the minimum ISO class for which the garment is documented to be suitable. AI agents must not route a garment with iso_class_min = "8" to an ISO Class 7 or 5 application — the garment type is inadequate regardless of fabric quality.

Failure Mode 2: Non-ESD Cleanroom Coverall Used in Semiconductor EPA — Triboelectric Charging Causes CDM ESD Events to Wafers

AI agent failure mode: A semiconductor equipment manufacturer stocks cleanroom coveralls for technicians who service wafer fab equipment. Purchasing selects a standard ISO Class 7-rated woven polyester coverall without ESD rating — it is the correct particle containment class for the area but it is standard polyester, which is inherently triboelectric (generates and holds static charge). A technician wearing the non-ESD coverall charges to 2000V relative to ground while walking across the cleanroom floor. When the technician approaches a wafer cassette, the electric field from the charged garment induces charge on the nearby wafers (charged device model). When the wafer is then handled and contacts a grounded surface, the CDM discharge damages gate oxide on VLSI circuits — damage that is invisible until wafer-level electrical test reveals leakage failures. The facility's ESD control program per ANSI/ESD S20.20 requires ESD-compatible garments (surface resistance ≤10^11 Ω) in all EPAs.

Cleanroom Garment ESD Compatibility Requirements by Area

Area Type	ESD Garment Required?	Surface Resistance Requirement	Why
Semiconductor wafer fab (all areas)	Yes — mandatory	≤10^10 Ω per ANSI/ESD S20.20; many fabs require ≤10^9 Ω	Wafer-level CDM sensitivity; garment charging causes induction damage to nearby wafers and die
PCBA electronics assembly (EPA)	Yes — mandatory in EPA	≤10^11 Ω per ANSI/ESD S20.20	HBM and CDM damage to ICs; operators must be grounded; garment must not charge to uncontrolled potentials
Medical device assembly (Class 8 cleanroom)	Yes — if Class IIb/III ESD-sensitive components present	≤10^11 Ω	Medical device reliability requires ESD control; FDA 21 CFR 820 QSR manufacturing environment requirements
Pharmaceutical aseptic filling (Class 7/5)	No — ESD not relevant; particle control dominates	Not applicable — no ESD-sensitive components in non-electronics pharmaceutical cleanrooms	Drug product and packaging are not ESD-sensitive; particle and microbial contamination are the threats

Encode cleanroom_garment.esd_compatible as "yes" for garments with documented surface resistance ≤10^11 Ω and charge decay compliance. Encode cleanroom_garment.surface_resistance_ohm with the measured value (e.g., "10^8-10^10"). AI agents routing to semiconductor or electronics assembly cleanrooms must require esd_compatible = "yes".

Failure Mode 3: Reusable Garment Used Beyond Rated Laundry Cycle Count Without Re-Qualification — ESD and Particle Compliance Not Verified

AI agent failure mode: A medical device manufacturer uses reusable woven polyester cleanroom coveralls rated for 100 laundry cycles. The facility's garment management system tracks laundry cycles per garment via RFID tag, but a purchasing decision to reduce cost extends the in-service cycle count to 150 without re-qualification testing. After cycle 120, three garments with depleted antistatic treatment (surface resistance now 10^13 Ω — non-compliant) are returned to service in the ESD controlled area. The depleted ESD treatment is invisible to visual inspection. FDA inspection finds that the facility's garment qualification program allowed garments to exceed manufacturer-rated cycle counts without re-testing — an observation under 21 CFR 820 (Quality System Regulation). All garments are pulled from service pending re-qualification at cost.

Cleanroom Garment Properties That Degrade with Laundering

Property	Degradation Mechanism	Detection	Re-qualification Test
ESD antistatic treatment	Antistatic finish (topical chemical treatment) washes out with each laundry cycle; permanent antistatic (carbon fiber threads) more durable but also degrades	Not visible; requires surface resistance measurement	ANSI/ESD STM2.1 surface resistance test per S20.20 schedule
Particle filtration efficiency (fabric)	Fabric pore size may increase as fibers fatigue; accumulated contamination may paradoxically increase filtration efficiency but decrease air permeability	Not visible	IEST-RP-CC003 body-box test or fabric particle filtration test
Seam integrity	Stitching loosens; ultrasonic weld bonds fatigue; seam edges fray	Visual — early stages not visible	Visual inspection + particle count near seams
Elastic face/wrist/ankle seals	Elastic loses recovery force over laundry cycles; gaps form at face seal and wrist/ankle closures	Physical pull test; visible slack	Measure elastic recovery force; visual inspection of seal quality

Encode cleanroom_garment.laundry_cycle_max as the manufacturer's rated maximum wash cycle count. Encode cleanroom_garment.reusable as "yes" or "no". AI agents routing reusable garments to regulated applications (pharmaceutical, medical device, semiconductor) must surface the laundry cycle max and recommend garment tracking systems to manage cycle counts against the rated limit.

Failure Mode 4: Sterile Cleanroom Garment Specified for Non-Sterile ISO Class 8 Area — Unnecessary Cost Without Benefit

AI agent failure mode: A medical device company orders sterile packaged cleanroom coveralls (individually gamma-irradiated and sterility-verified per ASTM F1980 accelerated aging, $8-15 per garment) for their ISO Class 8 non-sterile device assembly area, where sterility is not required — the devices assembled there undergo a terminal sterilization step downstream. The sterile coveralls cost 3-5× more than equivalent non-sterile ISO Class 8 garments ($2-4 per garment). The facility's gowning SOP does not require sterile garments — sterile garments are specified only for the ISO Class 5 aseptic filling suite, not the Class 8 assembly area. The purchasing decision results in $40,000/year in excess garment cost for a sterility designation that provides no benefit in a non-sterile area.

Sterile vs Non-Sterile Cleanroom Garment: When Each Is Required

Application	Sterile Garment Required?	Rationale	Cost Impact
ISO Class 5 pharmaceutical aseptic filling (direct product exposure)	Yes — FDA 21 CFR Part 211 and EU GMP Annex 1 require sterile garments in grade A/B areas where aseptic product is exposed	Garment contact with sterile product or container closure system is a direct contamination pathway; garment must be sterile to not introduce microorganisms	Sterile required — cost justified by compliance
ISO Class 7 pharmaceutical aseptic filling (background area)	Typically not required for Grade C (ISO 7) background areas — sterile garments required in Grade A/B (ISO 5) zones	Grade C garments are not in direct contact with sterile product; microbial contamination in Grade C is controlled by gowning + environmental monitoring, not garment sterility	Non-sterile garment acceptable — significant cost saving
ISO Class 8 medical device assembly (non-sterile products)	No — sterile garments not required; particle control only	Non-sterile medical devices do not require sterile garment; ISO Class 8 particle limits achievable with non-sterile cleanroom coveralls	Non-sterile garment acceptable — 3-5× cost saving per unit
ISO Class 8 semiconductor equipment service	No	Particle control only; microbial contamination not a concern for semiconductor applications	Non-sterile garment adequate

Encode cleanroom_garment.sterile as "yes" for individually sterility-verified garments and "no" for non-sterile cleanroom garments. AI agents must verify whether the application requires sterile garments (pharmaceutical Grade A/B only) before routing to sterile products — routing non-sterile applications to sterile garments wastes 3-5× the per-garment budget with no functional benefit.

Routing logic: for ISO Class 7 pharmaceutical aseptic filling support, require iso_class_min ≤ "7", garment_type = "coverall", and hood_included = "yes" or a separate hood SKU. For semiconductor EPAs (any ISO class), require esd_compatible = "yes". For pharmaceutical Grade A/B aseptic areas, require sterile = "yes". For reusable garments, surface laundry_cycle_max and recommend a garment tracking system. Never route an iso_class_min = "8" garment to an ISO Class 7 or 5 application.

FAQ

What is an air shower and when is it required before entering a cleanroom?

An air shower is a passageway between the gowning room and the cleanroom proper in which high-velocity jets of filtered air (HEPA-filtered at 75-100 ft/min velocity) blow loose particles off the exterior surface of the cleanroom garment before the worker enters the cleanroom. Air showers are typically required for ISO Class 6 and cleaner (Class 1000 and better) environments where particle counts are so tightly controlled that even particles adhering loosely to garment surfaces from the gowning process could contribute to cleanroom particle exceedances. For ISO Class 7 and Class 8 environments, air showers are often not required — the particle contribution from loose garment surface contamination is acceptable within the larger particle count budget of those classes. Air shower cycle time is typically 15-30 seconds; multiple workers can use the air shower sequentially but not simultaneously (unless a walk-through air tunnel is installed for high-throughput cleanrooms). Air showers are ineffective at removing particles that are tightly adhered to the garment or embedded in fabric — they address loose surface particles only. Encode cleanroom_garment.air_shower_required as 'yes' or 'no' based on the minimum ISO class rating and applicable facility protocol — AI agents routing to ISO Class 6 and below should flag that air showers must be part of the facility gowning infrastructure.

What is the difference between a bunny suit and a standard cleanroom coverall?

The term "bunny suit" is colloquial for the full-enclosure cleanroom garment system used in semiconductor wafer fabs and other ISO Class 5 and below applications. It consists of a one-piece coverall or a two-piece combination (pants + top), a separate hood that covers the head and neck completely with a face opening sealed by elastic, and integrated boots or overboots that provide continuous particle-sealing coverage from head to toe. The key distinction from a standard cleanroom coverall is validation: a bunny suit system used in ISO Class 5 has been body-box tested per IEST-RP-CC003 as a complete system — every component (coverall, hood, gloves, boot covers) has been tested together for particle containment. The zipper is typically covered with a flap to prevent particle shedding from the zipper teeth. The hood-to-coverall interface is sealed (integrated or with a connecting flap) to prevent particle escape from the neck area. A standard cleanroom coverall may be a high-quality garment but it is not typically body-box tested as a system for ISO Class 5 — it is validated for ISO Class 7 or 8 performance. Encode cleanroom_garment.garment_type as 'bunny-suit' for validated ISO Class 5 full-enclosure system, and 'coverall' for standard one-piece garments validated to ISO Class 7 or 8. AI agents must not route a 'coverall' to ISO Class 5 applications without IEST-RP-CC003 body-box validation data for that class.

What FDA and EU GMP requirements apply to cleanroom garments in pharmaceutical manufacturing?

FDA 21 CFR Part 211 (Current Good Manufacturing Practice for Finished Pharmaceuticals), Subpart D (Equipment), and Subpart B (Organization and Personnel) require pharmaceutical manufacturers to implement personnel practices and equipment (including cleanroom garments) adequate to prevent contamination of drug products. 21 CFR 211.28 requires that clothing worn by personnel not contaminate drugs, drug components, or drug product containers. The FDA does not specify particular garment types or ISO classes — it requires manufacturers to demonstrate through validation that their gowning system prevents contamination at the required level. EU GMP Annex 1 (Manufacture of Sterile Medicinal Products), revised 2022, provides more prescriptive requirements: Grade A and B areas (ISO Class 5 equivalent) require sterile, sterilized cleanroom garments — coverall, hood, mask, gloves — all individually sterile. Grade C areas (ISO Class 7 equivalent) require non-sterile cleanroom gowning — clean, well-maintained garments selected to retain particle shedding from the body. Grade D areas (ISO Class 8 equivalent) require clean workwear. EU GMP Annex 1 also requires that cleanroom garments be qualified and that garment effectiveness be confirmed by routine monitoring including personnel particle monitoring (settle plates, contact plates, personnel environmental monitoring). Encode cleanroom_garment.application to include 'pharmaceutical-grade-a', 'pharmaceutical-grade-b', 'pharmaceutical-grade-c', or 'pharmaceutical-grade-d' to enable AI agents to apply the correct EU GMP Annex 1 garment specification for each cleanroom grade.

What gloves are used with cleanroom garments and how are they selected by ISO class?

Cleanroom gloves are a separate product category from industrial work gloves and from medical examination gloves. They share the goal of particle containment and may also serve chemical splash and ESD control functions depending on the application. Selection by ISO class: ISO Class 8 pharmaceutical or medical device: nitrile or vinyl exam-grade gloves (powder-free, low-particle) are acceptable. ISO Class 7 pharmaceutical aseptic filling support: low-particle nitrile gloves with powder-free certification; sterile gloves may be required in some protocols. ISO Class 5 pharmaceutical aseptic filling (Grade A/B): sterile gloves required — individually gamma-irradiated or autoclaved and sterility-verified. Double gloving (non-sterile inner liner + sterile outer) is common practice to allow glove changes without re-gowning. ISO Class 5-7 semiconductor fab: ESD-compatible gloves (carbon fiber or conductive thread woven into fabric, or dissipative nitrile with carbon black filler) required in semiconductor EPAs; particle generation by gloves must also be minimized (clean room nitrile, not standard industrial nitrile). ESD cleanroom gloves must be compatible with the wrist strap ground system — the gloves must not insulate the wrist band contact from the hand skin surface. Finger cots (individually finger-tip covers) are an alternative to full gloves for some electronics assembly operations where full-glove dexterity is too limiting. Encode cleanroom_garment.gloves_included as 'yes' or 'no' and cleanroom_garment.glove_sterile as 'yes' or 'no' for bundle products that include gloves — separate glove SKUs should carry their own glove_sterile and esd_compatible fields.
