1.1本规程涵盖了橡胶和炭黑制造行业广泛的化学和物理测试操作特征的测试和采样的标准术语和一些基本概念。 1.2除了基本概念和术语外，附录A1中给出了测试测量过程的模型。这是术语和其他测试概念的数学基础。它还可以用于进一步发展这种做法，以解决更复杂的采样操作。 1.3这一一般性主题需要综合处理，对术语进行顺序或层次发展，并进行大量背景讨论。还提供了一些辅助术语，使文档更加完备。术语D 1566无法满足这一要求。 1.4本标准无意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和健康实践，并确定监管限制的适用性。

1.1 This practice covers a standardized terminology and some basic concepts for testing and sampling across the broad range of chemical and physical testing operations characteristic of the rubber and carbon black manufacturing industries. 1.2 In addition to the basic concepts and terminology, a model for the test measurement process is given in Annex A1. This serves as a mathematical foundation for the terms and other testing concepts. It may also find use for further development of this practice to address more complex sampling operations. 1.3 This general topic requires a comprehensive treatment with a sequential or hierarchial development of terms with substantial background discussion. A number of ancillary terms are also given that make for a more self-contained document. This cannot be accommodated in Terminology D 1566. 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 and health practices and determine the applicability of regulatory limitations prior to use.
