Introduction

Fire is a threat to life and property due to heat (heat hazard), as well as the generation of toxic combustion streams, corrosive combustion streams and smoke (non-thermal hazards) create a threat. The fire started to ignite, and in some cases it could develop into a flash and a complete fire. Therefore, resistance to ignition in the assessment of the risk of fire Aspect is considered one of the most important characteristics of materials. If there is no light, there is no fire. For most materials (except for metals and some other elements), light-off occurs in the gaseous state. Combustible when mixed with air When the vapor temperature is high and the exothermic oxidation reaction rapidly spreads, the light-off begins to occur. The ease of ignition and the chemical nature of the vapor, the fuel / Air ratio and temperature are closely related. For liquids, flammable vapors result from the evaporation of the liquid, and the evaporation process depends on the temperature and chemical composition of the liquid. For solids, the flammable vapors result from pyrolysis when the solid temperature is sufficiently high. The evaporation process depends on the temperature and chemical composition of the solid, too Depending on the solid thickness, density, specific heat capacity and thermal conductivity. The ease of ignition of a sample depends on many variables. There are several factors to consider when evaluating ignitability. a) the geometry of the specimen, including the thickness, and the presence of edges, corners or joints; b) Surface direction; c) air velocity and direction; d) the nature and location of the light source; e) the size and location of the external heat flux; f) combustible material is liquid or solid. All electrical and electronic product design should consider the risk of fire and potential fire hazard. Design of components, circuits and equipment as well The purpose of the screening of materials is to reduce the potential risk of fire to the extent possible even in the event of foreseeable abnormal use, failure and failure Accepted level. IEC 60695-1-10 and IEC 60695-1-11 provide guidance on how this can be done. The primary purpose is to prevent live parts from causing ignition, and in the event of a fire, the fire must be limited to the housing of the electrical and electronic product. Second, it is also important to minimize the extent of flame spread outside the product and to include heat, smoke, toxicity and corrosive combustion products Minimize the harmful effects. Fires involving electrical and electronic products may also be caused by non-electrical external ignition sources. The overall risk assessment should take this factor into account. This section gives an overview of the ignitability of electrical and electronic products and their relevance to the risk of fire. Fire hazard testing for electric and electronic products Part 33.
