This standard is equivalent to the International Electrotechnical Commission standard IHC695-4 (1993-10 2nd edition) Campfire risk test Part 4A: Fire test term 3. The original English reference is the main text of the standard, but for the sake of Chinese users, Appendix A (for reference) is added to the text, Chinese version. In this way, By making the product fire hazard test terms of our country equivalent to those of China, both sides can adapt to the needs of China's information technology and economic exchanges as soon as possible.
The main difference between this standard and the previous standard GR5T69.T-85 is that in addition to expanding the original scope of fire hazard, it also adds safety-related terms. A total of 49 new terms are added;
Added Chinese index
This standard replaces B5165.1-Fire Hazard Test Terms for Electrical and Electronic Products.

IEC Foreword
1) The International Electrotechnical Commission (IEC) is a world-class standardization organization formed by the International Electrotechnical Commission (IFC). Its purpose is to promote international cooperation in various standardization issues in the field of electrical products. For this purpose, in addition to organizing In addition to other activities of the organization, it also publishes various international standards and entrusts the formulation of official international standards to technical committees. The national committees responsible for the issues discussed can participate in this formulation work. At the same time, government organizations and single government organizations such as international standard organizations that are related to the document can also participate in this plan. IEC works closely with it under the conditions stipulated in the agreement reached with other international organizations (150). In essence, the formal decisions or agreements on technical issues are formulated by the national committees with the support of the representatives of the national committees interested in the issue. It tries its best to achieve international consensus on the issue. ) These agreements or recommendations are published in the form of standards, technical reports or other specifications and are recommended for international use. The significance of this meeting is: 1. Considering the preparations received by the national committee,
) In order to promote international coordination, the American National Committee has committed to using the corresponding standards or regional standards as much as possible. If there are any inconsistencies between the standards and the corresponding national standards or regional standards, the national standards or regional standards should be clarified as much as possible.
International Standard C5-4 is IE:89, the first fire hazard test technical requirements were formulated by the Committee. The second edition of this technical standard replaces the first edition written in 1989. It is composed of a small number of revisions and the addition of new terms and definitions in the first edition.
The provisions of this standard are based on the first edition and are compiled in accordance with the following documents: International Standard Non-Draft
