1.1 本规程描述了当需要作为其他试验方法的准备步骤时，安全气囊织物加速老化的程序。 1.1.1 在节中 7. ，本规程列出了四种加速老化的方法，这些方法与安全气囊的设计和制造有关。具体如下: 描述 部分 循环老化（选项“A”或“B”） 8.4 热老化（选项“A”或“B”） 8.4.3.1 湿度老化（选项“A”或“B”） 8.7 臭氧老化 8.8 1.2 当需要对老化织物试样进行后续物理性能测试时，本规程可与其他ASTM测试方法结合使用。 1.3 买方和供应商可通过协议使用本实施规程中规定以外的程序和仪器，并在报告中确认与标准实施规程的具体偏差。 1.4 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不是精确的等价物；因此，每个系统必须相互独立使用。 1.5 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。 1.6 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====== 5.1 对于安全气囊，进行加速老化的实践旨在确定暴露于热、湿度或臭氧或其组合对织物的加剧影响。这些环境条件也可以组合循环。安全气囊设计和制造中涉及的四种加速老化程序被称为循环老化、热老化、湿度老化和臭氧老化。 5.2 本规程中描述的环境条件旨在允许限制，以便在不同织物和不同实验室之间进行可靠比较。 5.3 为了精确可靠地比较不同织物的物理性能，有必要准确控制织物所处的湿度、温度、臭氧和循环条件。 5.4 织物试样按照加速老化后对试样进行的试验方法的要求进行配置。 5.5 除非买方和供应商之间的协议另有规定，否则本规程应构成调节和老化安全气囊织物的条件、程序和设备。它旨在作为制定书面材料规范的指南。当（基于经验）考虑到织物性能、材料处理设备或安全气囊系统设计另有规定时，买方和供应商的规范或协议可能会偏离本文所述惯例。

1.1 This practice describes the procedures for the accelerated aging of inflatable restraint fabrics when required as a preparatory step for other test methods. 1.1.1 In Section 7 , this practice lists four methods for conducting accelerated aging that are of concern to the design and manufacture of inflatable restraints. They are as follows: Description Section Cycle aging (Option “A” or “B”) 8.4 Heat aging (Option “A” or “B”) 8.4.3.1 Humidity aging (Option “A” or “B”) 8.7 Ozone aging 8.8 1.2 This practice may be used in conjunction with other ASTM test methods when subsequent tests of physical properties are required of aged fabric specimens. 1.3 Procedures and apparatus other than those stated in this practice may be used by agreement between the purchaser and the supplier with the specific deviations from the standard practice acknowledged in the report. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. 1.5 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. 1.6 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 ====== 5.1 For inflatable restraints, practices for conducting accelerated aging are designed to determine the aggravated effects on a fabric from exposures to heat, humidity, or ozone, or a combination thereof. These environmental conditions may also be cycled in combination. The four accelerated aging procedures of concern to the design and manufacture of inflatable restraints are referred to as cycle aging, heat aging, humidity aging, and ozone aging. 5.2 The environmental conditions described in this practice are designed to allow restraints so that reliable comparisons may be made between different fabrics and different laboratories. 5.3 In order to achieve precise and reliable physical property comparisons of different fabrics, it is necessary to control accurately the humidity, temperature, ozone, and cycling conditions to which the fabric is subjected. 5.4 Fabric specimens are configured in accordance with the requirements of test methods to be conducted on the specimens subsequent to accelerated aging. 5.5 Unless otherwise specified by agreement between the purchaser and the supplier, this practice shall constitute the conditions, procedures, and equipment by which inflatable restraint fabrics are conditioned and aged. It is intended to be used as a guideline in establishing a written material specification. The specification or agreement of the purchaser and the supplier may deviate from the practices described herein when (based on experience) considerations of fabric properties, material handling equipment, or inflatable restraint system design dictate otherwise.
