Introduction
The design of all electrical and electronic products needs to consider fire risk and potential fire hazards. Component, circuit and equipment design and materials
The purpose of material screening in this regard is to reduce the potential risk of fire accidents to the allowable range, even if foreseeable misuse, failure and loss occur.
The same is true for efficiency and so on. IEC 60695-1-10, IEC 60695-1-11 and IEC 60695-1-12 provide information on how to achieve this
The guidelines.
Fires involving electrical and electronic products may also be caused by external non-electric heat sources. The overall risk assessment should consider this factor.
The purpose of the IEC 60695 series of standards is to save lives and protect property by reducing the number of fires or reducing the consequences of fires. it
able to pass.
● Try to prevent ignition of live parts. If ignition occurs, limit the fire to the enclosure of electrical and electronic products.
● Attempt to minimize the spread of 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.
The heat (heat hazard), toxic and/or corrosive compounds, and blurred vision caused by smoke from a fire are all harmful to life and property.
Cause harm. With the increase of heat release, the risk of fire increases, and it may develop into a fire with flashover phenomenon.
One of the most important measurement methods in a fire test is to measure the amount of heat released, which is an important factor in determining the risk of fire; it is also a fire safety
One of the parameters of the whole project calculation.
Measuring and using heat release and other fire test data can be used to reduce the possibility (or impact) of fire, even if electrical and electronic products
The same is true for the predictable abnormal use, failure or failure of the product.
When a material is heated by an external heat source, it will produce a combustion flow, and when mixed with air, it will ignite and cause a fire. Release during this process
Some of the heat is taken away by the mixture of combustion flow and air, some is lost due to radiation, and some are returned to the solid material, making it more
More high-temperature decomposition products, thereby continuing this process.
Heat may also be transferred to other combustible products nearby, and release increased heat and combustion flow.
The release rate of thermal energy during a fire is defined as the heat release rate. The rate of heat release affects flame spread and secondary ignition, so it is very
important. Other parameters are also important, such as flammability, flame spread and boundary effects of fire, etc. (see GB/T 5169 and IEC 60695
Standard series).
