1.1 本规程描述了一种主要用于包装的压敏胶带暴露于实验室加速风化环境的环境。 1.2 本规程描述了样品制备及其应暴露的加速环境。它没有规定暴露的时间长度，也没有规定暴露后应对材料进行什么测试。 1.3 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。 1.4 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====== 4.1 本规程描述了一种主要用于包装的压敏胶带加速老化的方法。它不用于评估长期户外暴露条件下使用的压敏胶带的风化特性（见规程 D5105 ). 4.2 这种做法不一定提供自然暴露的直接模拟。 4.3 在确定相关材料的令人满意的相关性之前，不得将使用本规程的结果表示为等同于任何自然风化试验的结果。 4.4 当操作条件在实践中规定的仪器的可接受范围内变化时，结果可能会发生变化 G151页 和 G155页 .

1.1 This practice describes one environment for the exposure of pressure-sensitive tape, used primarily for packaging, to a laboratory accelerated weathering environment. 1.2 This practice describes sample preparation and the accelerated environment to which it shall be exposed. It does not specify the length of time of the exposure nor what tests shall be performed on the material following the exposure. 1.3 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. 1.4 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 ====== 4.1 This practice describes one method for accelerated weathering of pressure-sensitive tapes used primarily for packaging. It is not intended for evaluation the weathering characteristics of pressure-sensitive tapes used in long-term outdoor exposure conditions (see Practice D5105 ). 4.2 This practice does not necessarily provide direct simulation of natural exposure. 4.3 Results from use of this practice shall not be represented as being equivalent to those of any natural weathering test until a satisfactory degree of correlation has been established for the material in question. 4.4 Variation in results are possible when operating conditions vary within accepted limits for the instrument specified in Practices G151 and G155 .
