1.1 本指南涵盖并提供了乙烯产品分析的方向，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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1 当乙烯产品的各个生产商和用户处理分析测试中获得的结果时，单元和测试方法的不一致可能会导致重大错误。 本指南概述了乙烯产品中可能成分的典型浓度、分析中使用的方法和测量单位。本概述旨在提高方法和报告单元的一致性，从而将错误降至最低。乙烯产品的每个生产商和用户应立即审查本指南，以提高其对所用各种分析方法、测量单位和可能成分浓度水平的认识。 4.2 虽然本指南不适用于规范，但它可以为各方提供一个起点，以制定符合各自要求的相互商定的规范。它也可以作为寻找乙烯组分合适测试方法的起点。

1.1 This guide covers and 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 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. ====== Significance And Use ====== 4.1 When the various producers and users of ethylene product deal with the results obtained in analytical testing, inconsistency of units and test methods may cause major errors. This guide provides an overview of the typical concentrations of the possible components found in ethylene product, the methods used in analysis, and the units of measure. This overview is intended to be used to improve the consistency of methods and the units reported so that errors are minimized. Each producer and user of ethylene product should immediately review this guide to improve their awareness of the various analytical methods in use, the units of measure, and concentration levels of the possible components. 4.2 Although this guide is not to be used for specifications, it can provide a starting point for the various parties to develop mutually agreed upon specifications that meet their respective requirements. It can also be used as a starting point in finding suitable test methods for ethylene components.
