1.1本指南为乙烯产品的分析提供了方向，使分析员能够了解可能的测试方法、测量单位和可能成分的潜在浓度范围，从而提高分析测量的一致性。本指南不打算作为乙烯产品的一套规范使用，也不以任何方式解释。 1.2以国际单位制表示的数值应视为标准。 1.3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 guide provides direction for the analysis of ethylene product in a way that allows the analyst to know the possible test methods, the units of measure, and the potential concentrations range of possible components, so that the consistency of the analytical measurements is improved. This guide is not intended to be used, nor to be construed in any way, as a set of specifications for ethylene product. 1.2 The values stated in SI units are to be regarded as the standard. 1.3 This standard does not purport to address all of the safety problems, 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.
