Summary This standard specifies the explosion pressure resistant explosion pressure shock resistant and equipment requirements. This standard applies to the process of resistance to explosive devices and systems. Does not apply to individual parts of equipment such as motors, gearboxes, etc. These parts can be designed to meet the non-electrical equipment for explosive atmospheres flameproof enclosure type "d" requirements for the structure to withstand an internal explosion. This standard applies to the environmental conditions: atmospheric pressure range 0. 08MPa ~ O. 11MPa, a temperature range of -20��C ~ +60��C. This standard environment outside the range of the effective use of the equipment design, manufacture, inspection and marking also help, provided that such equipment is no specific standard requirements. This standard applies to possible deflagration devices and device combinations, does not apply to possible detonation devices and device combinations. This standard can not be used for offshore facilities.

Foreword

This standard is a reference to EN14460.2006 "anti-explosive devices" (in English) to develop, the technical content is equivalent to using the standard. Appendix A of this standard is a normative appendix, Appendix B is an informative annex. The standard proposed by China Electrical Equipment Industrial Association. This standard by the national explosion-proof electrical equipment Standardization Technical Committee (SAC/TC9) centralized and explain. This standard is mainly drafted by. Nanyang Explosion Electric Institute, the national explosion-proof electrical products for Quality Supervision and Inspection Center, coal scientific research General Hospital Shanghai Branch blast Electric Co., Ltd. The main drafters. Zhang Gang, Maqiu Ju, Liu  Yun, Zhang Xian force, Li Bin, Li Shu Dynasty, Liu Sijing.

Introduction

Complete explosion safety measures include the following points principles and manufacturers must be taken. a) prevent the formation of explosive atmospheres; b) to prevent the ignition of explosive environment; and c) If you still exploded, immediately stop and/or explosion flames and explosion pressures to limit the scope of a sufficient level of safety. If the ignition hazard assessment shows that the equipment can not meet the level requirements specified purpose equipment required (for example, adopted in accordance with the "explosive Ignition protection type of ignition source prevention), you need to take c) above method environment with non-electrical equipment "series of standard definition. The standard gauge Given the explosion-resistant equipment. It is a term used in the explosion-resistant housing structure, indicating that it can withstand the expected explosion pressure without rupture. Device has this feature, you can scope explosion flames and explosion pressure limit adequate security levels. This "anti-explosion" feature can be used for equipment, protective systems and components. Explosion resistant equipment

1 Scope

This standard specifies the requirements for explosion pressure resistant and explosion pressure shock resistant device. This standard applies to the process of anti-explosive devices and systems. Not a single part for a device such as motors, gearboxes, etc., which These can be designed as part of the structure in line with non-electrical equipment for explosive atmospheres flameproof enclosure type "d" requirement, it can withstand an internal explosion. This standard applies to the environmental conditions. atmospheric pressure in the range of 0.08MPa ~ 0.11MPa, temperature range of -20 ℃ ~ + 60 ℃. The standard for the design, manufacture, inspection and marking outside of the effective range of the device used in an environment also help, provided that such a set Preparation no specific standards. This standard applies to devices and device combinations may occur knocking does not apply to devices and device combinations may occur detonation. The standard Registration is not available for offshore installations. NOTE. This standard applies only to devices made of a metal material.
