1.1 This test method measures the ability of a vapor protective ensemble (VPE), including seams, and closures to maintain a fixed, positive pressure.
1.2 This test method measures the integrity of the suit, glove, boot/bootie, and visor materials, as well as the seams, and closures of a VPE. Exhaust valves fitted in the VPE must be sealed or blocked for this test and therefore are not functionally tested.
1.3 The values as stated in inch-pound units are to be regarded as the standard.
1.4 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. For specific hazard statements, see Section 7.
