National explosion-proof product implementation standards

National explosion-proof product implementation standards

GB 38361-2000
This standard is based on the international standard IEC 60079-0:1998 (Electrical Equipment for Explosive Gas Atmospheres Part 0: General Requirements)
The amendments to GB 3836.1-1983 are equivalent to the IEC 60079-0:1998 in terms of technical content, and the writing rules are equivalent and conform to
GB/T 1. 1-1993.
This standard is divided into the following sections under the general title of "Electrical Equipment for Explosive Gas Environments":
Part 1: General requirements
Part 2: Flameproof "d"
Part 3: increased safety die;
Part 4: Intrinsically Safe 6il)
Part 5: Positive pressure type + p11
Part 6: Oil-filled type 960.9
Part 7: Sand filling type,"
Part 9: encapsulated 66MH
In the case of the revision of GB 3836.1-1983 according to IEC 60079-0; 1998, in order to solve the fire protection of non-metallic materials of Class I electrical equipment
The problem has increased the flame retardant performance requirements for plastic casings. See Appendix E,
This standard also retains part of GB 3836.1-1983:
1) Inspection procedures to meet the needs of China's explosion-proof electrical products inspection, see Appendix A,
2) The moisture-proof requirements of Class I electrical equipment to meet the special requirements of the humid environment conditions of coal mines in China, see Appendix C,
3) Type I hand-held or bracket-type electric drill (and the included plug-in unit), portable instrumentation, and the outer casing of the lamp can be tensile-strengthened
The light alloy is not less than 120 MPa and is qualified according to the friction spark test method specified in GB 13813. Keep this content to
Solve the problem of lightweighting of some special hand-held electrical equipment in China (see 8-3).
Compared with GB 3836.1-1983, this standard has the following important changes:
1) The revision of the standard name, that is, the "explosive environmental electrical equipment for explosive atmospheres" is changed to "electrical equipment for explosive gas atmospheres";
2) Revise the term â€œexplosive gas mixtureâ€ to â€œexplosive gas environmentâ€;
3) The plastic case solves the problem of electrostatic charge buildup, increases the "shell surface area" limit, and "prevents the structure of electrostatic charge accumulation".
"Anti-photoaging regulations", "flame retardant performance regulations", etc.
4) Revised the regulations for the magnesium content of light metals used in the outer casing of Class I electrical equipment.
5) The size of the outer grounding connector is revised to be the same size as the inner grounding connector;
6) The surface resistance measurement method of the plastic case is revised to measure "the distance (10 Â± 0.5) mm, the length (100 Â± 1) m m, the width ((1 Â± 0.2)
The resistance between two parallel straight segments of mm;
7) Added Ex components, fuses, plug-in devices, portable lights and cap lights;
8) In the test part, plastic flame retardant test, plastic light aging test, light alloy friction spark safety test, etc. were added;
9) Class I electrical equipment unprotected transparent parts, in the case of high mechanical hazards, impact test energy from GB 3836.1-1983
10J was reduced to 7J, and the ambient temperature of the impact test was revised from (25 Â± 10) 'C to (20 Â± 5) 'C;
1 canceled the requirement for the impact test of the glass transparent piece with a nylon punch.
11) When the explosion-proof electrical equipment is submitted for review, only the manufacturer is required to send information related to the explosion-proof performance, but the quality of the factory products is increased.
Requirements for documents and documents.
This standard is the basic standard for electrical equipment used in explosive gas environments. When the explosion-proof electrical equipment product standard conflicts with this standard, the standard shall be
Subject to standard.
GB 3836.1-2000
This standard shall replace GB 3836.1-1983 from the date of implementation.
Appendix A, Appendix C, Appendix D, Appendix E, and Appendix F of this standard are appendices to the standard.
Appendix B and Appendix G of this standard are appendices to the tips.
This standard was proposed by the National Machinery Industry Bureau.
This standard is under the jurisdiction of the National Technical Committee for Standardization of Explosion-proof Electrical Equipment.
This standard was drafted: Nanyang Explosion-proof Electric Research Institute of the Ministry of Machinery Industry, Fushun Branch of the Coal Science Research Institute and Chongqing Branch, Shenyang
Electric Drive Research Institute, etc.
The main drafters of this standard: Guo Jiantang, Chen Zaixue, Huang Rongguang, Wan Shaopai, Ji Minghuan, Wang Jun.
This standard was first published in August 1983 and the first revision in January 2000.
This standard is entrusted to the National Explosion-proof Electrical Equipment Standardization Technical Committee for interpretation.

IE C Foreword
1) The International Electrotechnical Commission (IEC) is an international standardization organization that is owned by all National Electrotechnical Commissions (IEC).
National Committees). The purpose of the IEC is to promote the international integration of all issues related to standardization in the electrical field.
Work. For this purpose, in addition to other activities, the IEC publishes international standards. Standards are entrusted to various technical committees. In the preparation
In doing so, any IEC National Committee interested in the topic can participate. In the development of standards, international, government and non-government
Sex and IEC-related organizations can also participate in the work. According to the conditions of negotiation between the two organizations, IEC closely follows international standards.
Organizational Organization (ISO) cooperation.
2) I EC's formal resolutions or agreements on technical issues reflect international consensus as much as possible because of the special feeling of the topic
National committees of interest are represented in the technical committee.
3) They have internationally accepted forms of recommendation, published in the form of standards, technical reports or guides, and in this sense
The committee approved.
4) In order to promote international unification, IEC National Committees agree to the maximum allowable range of national and regional standards.
Adopt IEC international standards. If there is a difference between the IEC standard and the corresponding national or regional standards, the text should be in the national standard.
It is clearly indicated in the middle.
5) The International Electrotechnical Commission (IEC) does not regulate the approval process. Therefore, when it claims that a certain equipment meets certain standards of international standards,
The Electrotechnical Commission does not assume any responsibility.
6) It is worth noting that certain parts of this International Standard may involve patent rights, and the International Electrotechnical Commission is equivalent to some or all
Will not be held responsible.
The international standard IEC 60079-0 was developed by IEC TC 31 "Technical Committee for Electrical Equipment for Explosive Atmospheres".
This third edition will remove and replace the second edition published in 1983 and will be technically revised.
This international standard is based on the European standard EN 50014 (1992) published by CENELEC.
This standard is based on the following documents
Bu/2 F4D8/ISFDIS ten 31R/2*524/%R*VD state
All the conditions approved by this standard can be found in the voting report listed in the above table.
