(Specification)Standard Specification for Arc and Flame Resistant Rainwear
Standard Specification for Arc and Flame Resistant Rainwear
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 may be exposed to thermal hazards of momentary electric arcs and open flames.
1.1.1 This specification does not apply to the electrical contact hazards or electric shock hazards involved with electric arcs.
1.1.2 This specification does not apply to flash fire hazards such as industrial hydrocarbon flash fires or other petrochemical flash fire hazards. 1.2 The objective of this specification is to prescribe fit, function and performance criteria for rainwear that meets a minimum level of thermal and physical performance when exposed to a laboratory-simulated electric arc or flame 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 may be exposed.
1.5 The in-service care and use of this rainwear is beyond the scope of this specification.
1.6 The values stated in inch-pound units are to be regarded as the standard. The SI units shown in parentheses are for information only.
1.7 The following safety hazards caveat pertains only 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.
