Introduction

The design of all electrical and electronic products needs to consider the fire risk and potential fire hazard. Design of components, circuits and parts And the purpose of material screening is to reduce the potential fire risk to allowable even if foreseeable misuse, failure and failure occur. Within range. The purpose of GB/T 5169 "Fire Hazard Test for Electrical and Electronic Products" is to reduce the number of fires or reduce the severity of fires. To save lives and protect property. It can be passed. ---Try to prevent live parts from triggering ignition. If ignition occurs, limit the scope of the fire to the enclosure of electrical and electronic products; --- Attempt to minimize the spread of the flame to the product shell, and to reduce combustion products including heat, smoke, toxic or corrosive gases, etc. The harmful effects of materials are minimized. GB/T 5169 is now composed of 33 parts, divided into three sub-fields. ---Fire hazard test evaluation guidelines and terminology standards, including 1 term and 5 evaluation guidelines, aimed at the professional field Provide guidelines and reference procedures for fire hazard assessment; ---Small-scale fire test standards, including 4 glow wire/hot wire basic test methods, 8 flame test methods, and 2 abnormal resistance The thermal capacity test method is intended to introduce the methods suitable for use by electrical and electronic equipment manufacturers and testing institutions, based on specific heat source models. A small-scale test method for the heat source that is intended to cause a fire; ---The hazard evaluation standard of combustion flow, including 2 corrosiveness, 2 smoke blur, 5 toxicity, 2 heat release, 2 flame surface Spread, the purpose is to provide measurement of the combustion flow toxicity, corrosivity, smoke blur and heat release of electrical and electronic products and their materials Guidelines and current technical status of test methods. This document is part 2 of GB/T 5169, the purpose of which is to give general guidelines for assessing fire hazards. The use of fire compartments, and the use of detection and suppression systems are important methods to reduce the risk of fire, but this document is not involved. Involving electricians Electronic product fires may also be caused by external non-electric ignition sources, and this factor should be considered in the overall risk assessment. The fire hazard assessment of electrical and electronic products is completed by conducting a fire hazard test. These fire hazard tests can be divided into two basic categories Type. Qualitative fire test and quantitative fire test. Whenever possible, the fire test of electrical and electronic products should carry out a quantitative fire test with the following characteristics. a) The test needs to consider the use environment of the product, that is, the expected final use conditions and predictable abnormal use conditions. This is Because dangerous fire conditions in some environments may not necessarily pose the same threat in different environments. b) The test may link the test results to the harmful effects of the fire and combustion flow, that is, heat and air-borne combustion products are related Threats to people and/or property in the final use environment. This association avoids obtaining performance levels that are not clearly related to fire safety Other possibilities, these performance levels will have human factors and occasional distortions. c) Considering that the impact of actual fire is usually multiple, the results of the test should be expressed in well-defined terms, and reasonable The scientific unit of the product, so that the effect of the product on the total fire consequences can be quantitatively assessed, and it can also be compared with the effect of other products. Compare. Although quantitative test is the first choice, the characteristic of qualitative fire test is that the test can provide a pass/fail and graded result. exist In some cases, it is appropriate to maintain these qualitative test methods or develop new qualitative test methods. This part of GB/T 5169 is determined Under which circumstances it is appropriate to maintain or develop qualitative tests. Fire hazard test for electric and electronic products Part 2.General rules for fire hazard assessment guidelines

1 Scope

This document provides general guidelines for fire hazard assessment, and the content relates to how to reduce the fire risk and potential impact of electrical and electronic products. To within the allowable range, as a guide for the rest of GB/T 5169. This document does not provide guidance on how to use fire compartments and use detection and suppression systems to reduce fire hazards. This document explains the relationship between fire risk and potential fire The applicability of fire hazard assessment provides guidance for the product standard committee. The calculation of fire risk is outside the scope of this document. This document emphasizes the importance of fire hazards and fire conditions in the risk assessment, and discusses the development of test methods for determining fire hazards. Guidelines. This document also discusses the different types of fire tests, especially the types of qualitative and quantitative fire tests. It also describes what is applicable to the product Maintenance and development of the qualitative fire test by the Standards Committee. This document is intended for product committees to prepare standards based on the principles specified in IEC Guide104 and ISO /IEC Guide51. One of the tasks of the Product Committee is to use this series of standards wherever applicable when compiling standards in this field. Unless relevant The standard specifically mentions or lists, otherwise the requirements, test methods or test conditions of this document will not apply.
