1.1 本试验方法用于验证特定材料设计特性。一些柔性阻隔材料的设计可以抵抗空气通过膜结构。这些材料的特点是无孔。本试验方法提供了一种方法，通过在特定时间段内用给定体积的空气在压力下挑战材料来验证该特性。 1.2 本试验方法的目的不是测量材料的扩散特性，也不是识别或量化可能导致泄漏的设计针孔损伤的存在。 1.3 单位- 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 该材料挑战在ISO-11607-1附录C中提出，作为一种规范性测试方法，以证明材料无孔且满足微生物屏障要求。

1.1 This test method is to be used to verify a specific material design property. Some flexible barrier materials are designed to have a resistance to the passage of air through the membrane structure. These materials are characterized as nonporous. This test method provides a means to verify this property by challenging a material with a given volume of air under pressure over a specific time period. 1.2 This test method is not intended to measure the diffusion properties of a material nor to identify or quantify the presence of pinhole damage to the design that may result in leaks. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. 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. ====== Significance And Use ====== 3.1 This material challenge is presented in ISO-11607-1 Annex C as a normative test method to demonstrate that a material is nonporous and satisfies the microbial barrier requirements.
