1.1 二元化学相容性图也称为相互反应性图，记录了与成对材料混合相关的危险。本指南为编制这些图表提供了帮助。它回顾了在编制此类图表中至关重要的一些问题:准确评估化学相容性、收集相容性信息的合适实验技术、结合用户友好性以及提供修订。 1.2 本标准概述了化学相容性图表的使用。 1.3 本指南还回顾了现有的公共域兼容性图表、其中的差异及其优缺点。 1.4 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。 1.5 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====== 5.1 各种美国政府法规禁止将不相容材料一起运输，并要求在过程危险和风险分析中考虑化学反应性。化学相容性图表是用于满足这些法规的工具之一。二元相容性图在普通教育、化工厂或实验室以及通常执行的任务可能导致化学混合物（例如在化学反应期间）的区域和操作中是有用的教学工具- 用分隔容器装运，储存在公共区域或合成废物。兼容性信息在过程危险评审（例如HAZOP）期间至关重要。这些图表可为DOT HM-183上的码头操作员提供指导，该图要求多室罐车相邻隔间上的材料兼容。它们提供的文件表明，在确定泄压装置的尺寸时，考虑了无意混合作为化学反应产生热量和气体的潜在来源的可能性。兼容性图表用作过程危险审查期间使用的检查表，图表本身的编制通常会引起人们对以前未知的潜在危险的注意。 5.2 二元图只考虑材料对，因此不涵盖操作中材料的所有可能组合。 常见的第三种成分，例如酸性或碱性催化剂，可以通过记录其他相容材料之间反应的催化潜力来涵盖，但图表的形式不能确保这一点。在二元图表中，可能会有反应性三元系统无法检测到。 5.3 AIChE化学过程安全组织中心（CCPS）在其最近的一本专著中建议使用该标准 ( 1. ) . 5. 该作品目前可从以下网站免费下载:http://www.osha.gov/SLTC/reactivechemicals/index.html.

1.1 A binary chemical compatibility chart also called inter-reactivity chart, documents the hazards associated with the mixing of pairs of materials. This guide provides an aid for the preparation these charts. It reviews a number of issues that are critical in the preparation of such charts: accurate assessment of chemical compatibility, suitable experimental techniques for gathering compatibility information, incorporation of user-friendliness, and provision for revisions. 1.2 The uses of chemical compatibility charts are summarized in this standard. 1.3 This guide also reviews existing public domain compatibility charts, the differences therein, and their advantages and disadvantages. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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 ====== 5.1 Various United States governmental regulations forbid incompatible materials to be transported together and require that chemical reactivity be considered in process hazard and risk analysis. A chemical compatibility chart is one tool to be used to satisfy these regulations. Binary compatibility charts are useful teaching tools in general education, in the chemical plant or laboratory, and for areas and operations where commonly performed tasks might lead to chemical mixtures such as might occur during co-shipment in compartmentalized containers, storage in a common area or compositing waste. Compatibility information is essential during process hazard reviews (for example, HAZOP). These charts may provide guidance to terminal operators on DOT HM-183 that requires that materials on adjacent compartments of multicompartment tank trucks are compatible. They provide documentation that the potential for inadvertent mixing as a potential source of heat and gas evolution from chemical reactions has been considered in sizing relief devices. Compatibility charts serve as check lists for use during process hazard reviews, and the preparation of the chart itself often brings attention to potential hazards that were previously unknown. 5.2 A binary chart only considers pairs of materials and therefore does not cover all possible combinations of materials in an operation. A common third component, for example, acidic or basic catalysts, may be covered by footnoting the potential for catalysis of a reaction between otherwise compatible materials, but the form of the chart does not ensure this. There may be reactive ternary systems that will escape detection in a binary chart. 5.3 The AIChE organization Center for Chemical Process Safety (CCPS) has recommended the use of this standard in one of their recent monographs ( 1 ) . 5 This work is currently available for free download from: http://www.osha.gov/SLTC/reactivechemicals/index.html.
