1.1 This test method measures the barrier effectiveness of a specimen of protective clothing upon continuous contact with a liquid.

1.1.1 Procedure A -For use when a value for the cumulative amount of chemical permeated in 1 h is desired.

1.1.2 Procedure B -For use when breakthrough detection time and permeation rate values are desired.

1.2 Although not addressed herein, the effect of the test chemical on the clothing material can be determined by comparing the weight or other physical properties of the specimen before and after the permeation test.

1.3 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.
