Significance and Use
This test method is normally used to evaluate the barrier effectiveness against liquids of materials used for protective clothing and specimens from finished items of protective clothing.
Finished items of protective clothing include gloves, arm shields, aprons, suits, hoods, boots, and the like.
The phrase “specimens from finished items” encompasses seamed and other discontinuous regions as well as the usual continuous regions of protective clothing items.
A substitute challenge liquid (for example, water) is appropriate in some cases. However, it is possible that differences in chemical and molecular properties (for example, surface tension) lead to different results.
1.1 This test method is used to test specimens of protective clothing and candidate materials and constructions to be used in protective clothing. The resistance to visible penetration of the test liquid is determined with the liquid in continuous contact with the normally outside surface of the test specimen.
1.2 In some cases, significant amounts of hazardous materials will permeate specimens that pass the penetration tests. For more sensitive analysis use Test Method F739 to determine permeation.
1.3 This test method is not applicable to finger tips or crotch areas of gloves, which are possible failure points.
1.4 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
1.5 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. Specific hazards are given in Section 7.
