Introduction

When designing any electrical and electronic product, consider the risk of fire and potential hazards. Components, Circuit and Device Design, and Material Screening The goal in this regard is to reduce the potential risk of fire accidents to an acceptable level even in the event of foreseeable abnormal use, failure And failure and other conditions as well. IEC 60695-1-10 and IEC 60695-1-11 provide guidance on how to achieve this goal. The main purpose is to prevent the ignition caused by live parts, and to limit the scope of ignition within the housing of the electric and electronic product if ignition occurs. The secondary purpose is to reduce the flame spread beyond the product envelope and to reduce the harmful effects of combustion products, including heat, smoke, toxic or corrosive gases influences. Fires involving electrical and electronic products may also be caused by external non-electrical sources. The overall risk assessment should take this factor into account. Fire heat (heat hazard), toxic and/or corrosive compounds, as well as smoke-induced visual blurring, are vital to life and property Cause harm. As the amount of heat released increases, the risk of fire increases and it may develop into a fire with a flashover phenomenon. One of the most important measurements of fire tests is the measurement of heat release, which is an important factor in determining the danger of fire; it is also a fire safety measure One of the parameters calculated by the whole project. Measurement and use of heat release and other ignition test data can be used to reduce the probability of fire (or impact), even though the electrotechnical Predictable non-normal product use, failure or failure of the situation as well. When a material is heated by an external heat source, a combustion flow is generated, which, combined with the air, ignites and ignites. This process is released Some of the calories and the mixture was burned and air away, and some because of radiation loss, and some return to the solid material to make it more Many pyrolysis, so as to continue this process. Heat may also be passed on to other nearby combustible products, releasing additional heat and burning flow. The rate of heat release during ignition is defined as the rate of heat release. The rate of heat release affects the spread of the flame and causes a secondary fire due to This is important. Other parameters are also important, such as flammability, flame spread and fire boundary effects (see GB/T 5169 and IEC 60695 standard series). This section is based on the use of taper calorimeters to measure the rate of heat release and also to measure other valid fire hazard parameters such as smoke output, Room and quality loss. In IEC 60695-1-40 reference is made to the heat release data required for the combustion of insulating liquids. This section provides the measurement of such material heat release The method of release, also applies to other flammable liquids. Conical calorimeters are given in ISO 5660-3 and IEC 60695-8-2 Guidelines. Fire hazard testing for electric and electronic products Part 32. Heat release of thermally released insulating liquid

1 Scope

GB/T 5169 provisions of this part of the insulating liquid used in electrical and electronic products are exposed to the provisions of a spark ignition heat flux, the test Quantitative insulation test method for heat release from insulating liquid combustion. And can determine the amount of smoke, light-off time and quality loss. This section is also suitable For other liquid samples. DANGER WARNING Explosions may occur when testing volatile liquids with this unit and should therefore be checked according to the initial test procedure set out in 8.1 liquid.
