1.1本试验方法测量蒸汽保护装置（VPE）保持固定正压的能力，包括接缝和封盖。 1.2本试验方法测量了防护服、手套、靴/靴和遮阳板材料的完整性，以及VPE的接缝和闭合情况。在本测试中，安装在VPE中的排气阀必须密封或堵塞，因此不进行功能测试。 1.3以英寸-磅为单位的数值应视为标准值。 1.4本标准无意解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。有关具体的危险说明，请参阅第7节。

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.
