1.1 本试验方法描述了用一面或两面涂有橡胶的织物测定空气保持力的方法。 1.2 以国际单位制或英磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；因此，每个系统应独立使用。组合两个系统的值可能导致不符合标准。 1.3 本标准并不旨在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、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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====== 4.1 本试验方法描述了一种评估用于制造气动物品的橡胶织物（即必须保持空气以在预期应用中令人满意的织物）的程序。这类物品的例子有应急筏、救生圈、海上娱乐设备、浮筒、浮筒和警告或探测装置，如浮标或气象气球。

1.1 This test method describes the determination of the retention of air by fabrics coated on one or both sides with rubber. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 ====== 4.1 This test method describes a procedure for evaluating rubberized fabrics that are used to manufacture pneumatic articles (that is, those that must retain air in order to perform satisfactorily in an intended application). Examples of such articles are emergency rafts, life preservers, marine recreational equipment, floats, pontons, and warning or detection devices, such as buoys or weather balloons.
