    1. Scope

    1.1 This document specifies special items of clothing (cleanroom garments) designed to protect aerospace products from electrostatic discharge and from contaminants released by personnel and garments. Special clothing includes low linting coveralls, footwear, and head covers.

    1.2 The function of cleanroom garments is to contain the contaminants generated by people and to minimize contaminants from the garments.

    1.3 Two types of fabrics can be selected for the garments. Both types are inherently static-dissipative materials in order to prevent electrical discharges that can damage sensitive hardware or initiate explosions in the presence of flammable vapors. The material specified for "hazardous environments" is flame resistant and provides additional protection to the wearer. Selection of garment design and fabric should be based on the user's needs with respect to functional and environmental requirements.

    1.4 Additional, background information can be found in SD-TR-91-26 and IES-RP-CC003.2.

    1.5 This standard is intended to be in compliance with the ASTM policy on Fire Standards. Flammability tests specified in this standard should be used to measure and describe the properties of fabrics in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fabrics under actual fire conditions. However, results of the tests may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of operations in controlled environment areas.

    1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    1.7 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information purposes only but are hard conversions.
