ISO 15031-2:2010提供了有关排放相关诊断中使用的术语、定义、缩写和首字母缩略词的使用指南，涉及道路车辆和该领域使用的外部设备之间的通信。它还规定了构建新术语的程序。由于它给出了适用于电气/电子系统的诊断术语的推荐用法，它还参考了相关的机械术语、定义、缩写和首字母缩略词。 ISO 15031-2:2010适用于所有轻型汽油和柴油乘用车和卡车，以及重型汽油车。本文件的具体应用包括诊断、维修和维修手册、公告和更新、培训手册、维修数据库、发动机罩下排放标签和排放认证应用。 ISO 15031-2:2010旨在帮助行业提供标准术语、定义、缩写和首字母缩略词，以建立诊断工具和出版物的通用术语。

ISO 15031-2:2010 provides guidance on the usage of terms, definitions, abbreviations and acronyms used in emissions-related diagnostics, with respect to the communication between road vehicles and external equipment used in that field. It also specifies a procedure for constructing new terms. As it gives recommended usage of diagnostic terms applicable to electrical/electronic systems, it also makes reference to related mechanical terms, definitions, abbreviations and acronyms. ISO 15031-2:2010 is applicable to all light-duty gasoline and diesel passenger vehicles and trucks, and to heavy-duty gasoline vehicles. Specific applications of this document include diagnostic, service and repair manuals, bulletins and updates, training manuals, repair databases, underhood emission labels and emission certification applications. ISO 15031-2:2010 is intended to help industry provide standard terms, definitions, abbreviations and acronyms with a view to establishing a common terminology for diagnostic tools and publications.
