标准摘要
[中文适用范围]: 本文件提供了易燃工艺流体与电气系统之间的工艺密封的具体要求,此类故障可能导致工艺流体直接迁移至建筑物配线系统。注:一些定义根据闪点区分术语“易燃”和“可燃”。在高压和/或高温条件下,可燃液体可能导致易燃雾状物和气溶胶的形成,这些均属于本技术规范的范围。 本文件包含对单一工艺密封设备、双重工艺密封设备和附加次级工艺密封的评估、制造和测试要求。本文件的要求不适用于 IEC 60079 系列或其他标准中涉及的导管密封装置、电缆格兰头和其他接线密封方法。本文件未涉及基本电气安全和防爆要求,但可能适用于正在调查的设备。本文件未涉及泄漏对环境的影响。 [外文原描述]: IEC TS 60079-40:2015(E) provides specific requirements for process sealing between a flammable process fluid and an electrical system where a failure could allow the migration of the process fluid directly into the premises wiring system. This document contains requirements for evaluation, construction and testing of single process seal equipment, dual process seal equipment, and add-on secondary process seals. The requirements of this document do not apply to conduit sealing devices, cable glands and other wiring sealing methods addressed in the IEC 60079 series or other standards. Requirements for basic electrical safety and explosion protection are not addressed by this document, but may apply to the equipment under investigation. The effects of leakage to the environment are not addressed by this document. Keywords: process sealing between a flammable process fluid and an electrical system
