AbolishedExplosive atmospheres—Part 5:Equipment protection by pressurized enclosure “p“
爆炸性环境 第5部分: 由正压外壳“p”保护的设备
Application Summary AI generated
This standard specifies the construction, testing, and marking requirements for electrical equipment protected by a pressurized enclosure "p" to prevent ignition of surrounding explosive atmospheres. It is applied in industries such as oil and gas, chemical processing, and mining, where equipment must operate safely in hazardous areas containing flammable gases, vapors, or dusts. The standard ensures that the enclosure maintains a positive internal pressure relative to the external atmosphere, preventing the ingress of explosive mixtures.
