1.1 这些实践提供了涵盖获取内反射光谱常用的各种技术的一般建议。 2. , 3. 讨论仅限于电磁光谱的红外区域，包括基本理论概述、确定获得结果的参数描述、最广泛使用的仪器、采样和获得有用光谱的实用指南，以及特定于内反射的解释特征。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 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 这些实践为内反射红外光谱学的良好实践提供了一般指南。

1.1 These practices provide general recommendations covering the various techniques commonly used in obtaining internal reflection spectra. 2 , 3 Discussion is limited to the infrared region of the electromagnetic spectrum and includes a summary of fundamental theory, a description of parameters that determine the results obtained, instrumentation most widely used, practical guidelines for sampling and obtaining useful spectra, and interpretation features specific for internal reflection. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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 These practices provide general guidelines for the good practice of internal reflection infrared spectroscopy.
