Yuanqin, Zheng Shaofeng:IntroductionThe 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 an acceptable level, even if foreseeable abnormal use occurs: The same is true for conditions such as use, failure and failure: IEC 60695-1-10 and IEC 60695-1-11 together provide information on how to achieve this guide: Fires involving electrical and electronic products may also be caused by non-electric external ignition sources: The overall risk assessment should consider this factor: The purpose of the IEC 60695 series of standards is to protect life and 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 the flame to the outside of the product, and to include heat, smoke, toxic or corrosive combustion products The harm impact is minimized: This section applies to the measurement and description of the non-contact flame source heat of materials used for electrical products and their components under controlled laboratory conditions: It is not suitable for describing or evaluating the fire hazard or fire risk of materials, products or components under actual fire conditions: Of course However, its test results can be used as elements of fire hazard assessment, which takes into account all relevant aspects of assessing the fire hazard of a specific end use: factor: Samples cut from finished products or components can be tested in this way: This section may involve hazardous materials, operations and equipment: It cannot solve all security issues related to its use: User is responsible Establish appropriate safety and health practices and determine the applicability of regulatory restrictions before use: Test methods for determining flammability through flame contact have been developed and standardized, such as IEC 60695-11-10[1] and IEC 60695- 11-20[2] and ISO 4589-2[3]: This method is the first to measure the characteristic heat flux (CHFI) of ignition in non-contact flame sources of electrical and electronic products and their component materials experiment method: CHFI investigates the ignition characteristics from the perspective of incident heat flux: This test method simulates materials used in electrical and electronic products The burning behavior of the material when the flame source is close to but not in contact with it: For example, candle flames are close to electrical and electronic products: Fire hazard test for electric and electronic products Part 46: Test flame in non-contact flame source Determination of characteristic heat flux during light-off1 ScopeThis part of GB/T 5169 gives the materials used to determine when electrical and electronic products and their components ignite in a non-contact flame source: The characteristic heat flux (CHFI) test method gives the relationship between light-off time and incident heat flux: Samples used in this test method Taken from finished products or components: This part is intended for product committees to compile 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 writing its own standards: Unless relevant Standard specifically mentioned or listed does not apply, otherwise the requirements, test methods or test conditions of this section are applicable:2 Normative referencesThe following documents are
