ASTM F2733 Standard Specification for Flame Resistant Rainwear for Protection Against Flame Hazards

1. Scope

1.1 This specification establishes applicable test methods,minimum physical and thermal performance criteria, a suggested sizing guide, and suggested purchasing information for
rainwear for use by workers who are potentially exposed to industrial hydrocarbon fires or other petrochemical fire hazards.

1.1.1 This specification does not apply to rainwear used for thermal electric arc flash hazards. Specification of rainwear for these electric arc flash hazards are addressed in Specification
F 1891.

1.2 The objective of this specification is to prescribe function and performance criteria for rainwear that meets a minimum level of thermal and physical performance when exposed
to a laboratory-simulated fire exposure.

1.3 This specification is not intended to serve as a detailed manufacturing or purchasing specification, but can be referenced in purchase contracts to ensure that minimum performance
requirements are met.

1.4 Controlled laboratory tests used to determine compliance with the performance requirements of this specification shall not be deemed as establishing performance levels for all
situations to which wearers of this protective clothing are potentially exposed.

1.5 This specification does not attempt to establish inservice care and use of this flame resistant rainwear.

1.6 The values stated in SI units are to be regarded as standard. The values given in brackets are mathematical conversions to inch-pound or other units that are commonly
used for thermal testing.

1.7 The following safety hazards caveat pertains to Sections 7 and 9 of this specification. 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.
