1.1本试验方法描述了测定单面或双面涂有橡胶的织物的空气保持力。 1.2以国际单位制或英寸-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是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.3 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法描述了一种用于评估用于制造气动物品的橡胶织物（即那些必须保持空气以在预期应用中令人满意地运行的织物）的程序。这类物品的例子有应急救生筏、救生圈、海上娱乐设备、浮标、浮桥和警告或探测装置，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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 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.
