1.1 这些试验方法包括橡胶鉴定，并基于热解产物（热解产物）和薄膜的红外检测。 1.2 这些试验方法适用于处于未加工状态的橡胶，以及在复合时处于固化和未固化状态的橡胶。 1.3 由于在红外分光光度法中通常使用波数（cm −1 )在整个试验方法中，使用的不是国际单位制中的频率单位赫兹（Hz），而是前者。 1.4 本试验方法假设样品和红外光谱由经验丰富的人员制备和分析，并且设备按照制造商的指示进行操作以获得最佳性能。本试验方法不包括红外分光光度计的操作细节。 1.5 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。 具体的预防说明见第节 17 . 1.6 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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 3.1 出于研究、开发和质量控制的目的，确定固化复合产品中橡胶的成分是有利的。 3.2 该测试方法利用红外技术提供这种成分分析。

1.1 These test methods cover rubber identification and are based on infrared examination of pyrolysis products (pyrolyzates) and films. 1.2 These test methods are applicable to rubbers in the raw state and, when compounded, both in the cured and uncured state. 1.3 Since it is customary in infrared spectrophotometry to use wavenumbers (cm −1 ) rather than Hertz (Hz), the unit for frequency in the SI system, the former is employed throughout this test method. 1.4 This test method assumes that specimens and infrared spectra are prepared and analyzed by experienced personnel and that the equipment is operated according to the manufacturer's direction for optimum performance. No details for operation of infrared spectrophotometers are included in this test method. 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. Specific precautionary statements are given in Section 17 . 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 ====== 3.1 For research, development, and quality control purposes, it is advantageous to determine the composition of rubbers in cured, compounded products. 3.2 This test method provides such composition analysis utilizing an infrared technique.
