1.1 本试验方法允许评估用于要求耐室外风化应用的橡胶化合物的相对能力。 1.2 本试验方法不适用于通常归类为硬橡胶的材料，但适用于模制或挤压软橡胶材料和海绵橡胶，用于车窗挡风雨条以及类似的汽车应用。 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、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（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====== 4.1 模制或挤压橡胶产品必须能够承受臭氧开裂和室外风化的影响，才能正常使用。该试验能够在室外试验的规定试验条件下对性能进行简单比较。 由于服务条件的广泛性，测试性能和服务性能之间没有直接的相关性。

1.1 This test method permits the estimation of the relative ability of rubber compounds used for applications requiring resistance to outdoor weathering. 1.2 This test method is not applicable to materials ordinarily classed as hard rubber, but is adaptable to molded or extruded soft rubber materials and sponge rubber for use in window weatherstripping as well as similar automotive applications. 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 Molded or extruded rubber products must withstand the effects of ozone cracking and outdoor weathering for satisfactory use. This test enables a simple comparison of performance to be made under specified test conditions in an outdoor test. No direct correlation between test performance and service performance can be claimed due to the wide range of service conditions.
