本文件规定了现场安装的密封件的具体要求，密封件安装在包含易燃或可燃工艺流体的加压系统（流）之间，该系统直接或间接连接至电气系统，故障可能导致工艺流体直接进入电气系统。本标准未具体说明电气安全的基本要求。本文件也未涉及工艺系统失控对环境和/或人员健康和安全的影响。

This document provides specific requirements for field installed sealing between a pressurized system (stream) containing flammable or combustible process fluids which is connected directly or indirectly to an electrical system where a failure could allow the migration of process fluids directly into the electrical system. The basic requirements for electrical safety are not specifically addressed by this standard. The effects of the loss of containment of the process system in terms of risk to the environment and/or personnel health and safety are also not addressed by this document.
