Full title and description

IEST-RP-CC003.5-2023 — Garment System Considerations for Cleanrooms and Other Controlled Environments. This Recommended Practice (RP) provides non‑mandatory guidance for selection, specification, maintenance, testing, and quality control of cleanroom garments and accessories used in non‑aseptic and aseptic controlled environments. It addresses garment system configuration, fabric types and properties, construction and measurement, laundering and processing, testing methods, and special considerations such as flame/arc protection and automated tracking of garment service life.

Abstract

IEST‑RP‑CC003.5 gives practical, non‑prescriptive recommendations to limit human‑generated contamination through appropriate gowning systems. The document summarizes factors that influence garment performance (fabric, construction, fit, and accessories), provides testing and acceptance approaches, describes laundering/maintenance and tracking practices, and includes appendices with recommended garment configurations, measurement guidance, flame/arc flash considerations, testing recommendations, and a bibliography. The RP is intended to support specification, procurement, validation, and ongoing quality programs for garment systems in controlled environments.

General information

• Status: Current (active Recommended Practice).
• Publication date: March 20, 2023.
• Publisher: Institute of Environmental Sciences and Technology (IEST).
• ICS / categories: 13.040.35 — Cleanrooms and associated controlled environments.
• Edition / version: IEST‑RP‑CC003.5 (5th edition / revision 3.5).
• Number of pages: 84 pages.

Scope

The RP covers gowning systems used to control particulate and molecular contamination generated by personnel in cleanrooms and other controlled environments. It is applicable to end users, facility designers, garment suppliers, launderers/processors, and quality personnel for non‑mandated guidance on garment selection, performance attributes, testing, maintenance, measurement, and documentation. The RP does not itself impose regulatory requirements nor replace facility‑ or process‑specific safety and occupational health obligations.

Key topics and requirements

• Gowning system concepts and recommended configurations for different air cleanliness classes (single‑piece, two‑piece, coveralls, hoods, boots, etc.).
• Fabric categories and material properties relevant to contamination control (particle shedding, filtration efficiency, permeability, durability, and electrostatic behavior).
• Design, fit and measurement guidance for garment construction and interfaces between garment components (appendix with measuring guide included).
• Laundering, processing, inspection, repair, and life‑cycle considerations for reusable garments.
• Tests and test methods to evaluate garment and fabric performance, and recommended acceptance/monitoring approaches.
• Considerations for flame‑ and arc‑protective garments adapted for cleanroom use (short‑duration hazards appendix).
• Use of tracking technologies (barcodes, RFID) to manage service life and traceability of garment inventories.

Typical use and users

Used by contamination‑control engineers, cleanroom operations managers, procurement/specification teams, garment manufacturers and launderers, validation and quality teams, and designers of controlled environments. Typical applications include semiconductor, pharmaceutical, biotechnology, medical device manufacturing, aerospace, and any facility requiring controlled airborne particulate or molecular contamination control.

Related standards

IEST‑RP‑CC003.5 is commonly used alongside other cleanroom and contamination control standards and guidance such as the ISO 14644 series (cleanroom classification and testing), relevant ASTM standards for cleanroom materials and test methods, GMP/Annex 1 guidance for aseptic pharmaceutical operations, and other IEST recommended practices addressing wiping materials, gloves, and testing of cleanrooms. Users typically reference these documents together when developing facility gowning and contamination control programs.
