ASTM-F1052:2020 Edition(Redline)

1.1 This test method measures the ability of a vapor protective suit, including seams and closures, to maintain a fixed, positive pressure over a specified period of time.

1.2 This test method does not measure vapor protection of suits. This test method measures the integrity of the suit, glove, foot protection, and visor materials, as well as the seams and closures of a vapor protective suit. Exhaust valves fitted in the vapor protective suit must be sealed or blocked for this test and therefore are not functionally tested.

1.3 The values as stated in in.-H₂O (mm-H₂O) 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
