本国际标准为制冷剂的指定提供了一个明确的系统。它还建立了一个系统，用于根据毒性和可燃性数据对制冷剂进行安全分类，并提供了确定制冷剂浓度限值的方法。表中列出了制冷剂名称、安全分类和制冷剂浓度限值，这些表基于可用数据。包含以下内容:BS ISO 817:2014+A1:2017

This International Standard provides an unambiguous system for assigning designations to refrigerants. It also establishes a system for assigning a safety classification to refrigerants based on toxicity and flammability data, and provides a means of determining the refrigerant concentration limit. Tables listing the refrigerant designations, safety classifications and the refrigerant concentration limits are included based on data made available.Incorporates the following:BS ISO 817:2014+A1:2017
