scope:

This standard establishes minimum performance and labeling requirements for secondary single-use flame resistant protective clothing. Such clothing is designed for use in industrial settings where flame hazards may exist and such clothing will not negatively impact the thermal performance afforded by the primary flame resistant protective clothing worn underneath. Protective clothing covered by this standard includes items such as, but not limited to, encapsulating suits, coveralls, jackets, pants, lab coats, aprons and sleeves.

NOTE: For single use and multiple use items, the word use is defined as exposure to chemical, flame or laundering.

NOTE: The performance requirements in this standard are not meant to assess garments intended for use as rainwear.

This standard does not specifically address individual testing of components and findings, which include but are not limited to zippers, elastic seam thread, zipper tape, buckles, hook and loop tape and draw cords. This standard does not address multiple use secondary single-use flame resistant protective clothing. This standard does not address protective clothing designed for protection from hot liquids, steam, or electric arc exposure. This standard does not address barrier performance requirements for chemical or biological protection afforded by the garment or ensemble.

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. 

Purpose

This standard is intended to provide manufacturers with minimum requirements for testing and labeling secondary single-use flame resistant protective clothing. The items detailed in this standard are intended for use in multihazard environments where combinations of liquid or solid particulate hazards are accompanied by the potential for exposure to flame hazards. It is not the intent of this standard to address all situations.
