The design of components, circuits and parts The purpose of material selection is to reduce the potential fire risk to an acceptable level even if foreseeable misuse, malfunction or failure occurs. The purpose of the Fire Hazard Test for Electrical and Electronic Products is to save lives by reducing the number of fires or the severity of fires. life and property. It can be achieved through. ---Prevent ignition of live parts as much as possible. If ignition occurs, limit the scope of the fire to the casing of the electrical and electronic products; --- Minimize the spread of flames to the product enclosure as much as possible, and reduce the risk of combustion including heat, smoke, toxic or corrosive gases. The harmful effects of the product are minimized. The Fire Hazard Test for Electrical and Electronic Products now consists of 40 parts, divided into three major areas. --- Fire hazard test assessment guidelines and terminology standards, including 1 terminology and 8 assessment guidelines, the purpose is to provide a professional field Provide guidance and reference procedures for fire hazard assessment; ---Fire test method standards, including 5 basic glow wire/hot wire test methods, 9 flame test methods, 2 abnormal heat resistance Capability test method, 1 arc ignition test method, the purpose is to introduce suitable for electrical and electronic equipment manufacturers and testing institutions Small-scale test methods using specific heat sources to simulate the heat sources that cause fires; ---Hazard assessment criteria for combustion flow, including 2 items of corrosiveness, 2 items of smoke blurring, 5 items of toxicity, 3 items of heat release, and 2 items of flame surface The purpose is to provide measurement of combustion toxicity, corrosiveness, smoke haze and heat release of electrical and electronic products and their materials. Guidelines and current technical status of test methods. This document describes the tests for the fire hazard of materials ignited by electric arcs. This document cannot be used alone to describe or evaluate materials, products or assemblies. The fire hazard or fire risk of a component under actual fire conditions. However, the results of this test can be used as an estimate of the fire risk taking into account the factors used. Elements of an ignition risk assessment that are relevant to the assessment of the ignition hazard for a specific end use. Fire hazard test for electrical and electronic products Part 49.Arc method Arc ignition test methods for materials1 ScopeThis document specifies the test principles and objectives, general requirements, test equipment, test specimens, State adjustment and test conditions, test procedures, safety technical measures and result determination. This document applies to arc ignition tests of solid materials used in electrical and electronic products. This test method is not applicable to materials that are easily bent or do not ignite when exposed to fire. Materials that curl up and expand when heated.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.
