All electrical and electronic products must be designed with fire risk and potential fire hazard in mind. Design of components, circuits and products, and The purpose of the screening of materials is to understand potential fires under normal operating conditions and in the case of reasonably foreseeable abnormal use, failure and failure. The risk is reduced to an acceptable level. IEC 60695-1-10 and IEC 60695-1-11 developed by IEC /TC89, how to achieve This purpose provides guidance. The primary purpose of IEC 60695-1-10 and IEC 60695-1-11 is to provide guidance for the following actions. a) prevent the ignition of live parts; b) If ignition occurs, the fire is confined to the electrical and electronic product enclosure. The secondary purpose is to minimize the extent to which the flame spreads outside the product, as well as to the combustion stream such as heat, smoke, toxicity and/or corrosive Harmful effects are minimized. Fires involving electrical and electronic products may also be caused by non-electric external sources of ignition. This factor should be considered in the overall risk assessment. In electrical equipment, superheated metal parts can be used as an ignition source. In the glow wire test, it is simulated with a hot glow wire. Source. IEC 60695-2-10 describes a glow wire test device and a general test method, IEC 60695-2-12 describes the glow wire of the material. The flammability index (GWFI) test method, IEC 60695-2-13, describes the glow wire light-off temperature (GWIT) test method for materials. This section is used to assess the response of a finished product to heat when it is in contact with a heating wire under controlled laboratory conditions. This facilitates exposure to overheating stress Evaluation of finished products in (eg, fault current through wires, overload of components, and/or poor contact). This section cannot be used alone for description or review. Estimate the risk of fire or fire of a product or component under actual fire conditions. However, the results of this test can be taken into account for all factors The element of the fire risk assessment, which is related to the ignition risk assessment for a particular end use. This section may involve hazardous materials, operations, and equipment. Its purpose is not to solve all the security issues related to it. question. Users of this section should take appropriate safety and health measures and determine their applicability and limitations before using this section.

In addition, this test method does not apply to small parts (see 4.4) test. 4.2 Complete finished product The specimen should be a complete finished product rather than a finished part (see 4.3). The choice of sample should consider shape, ventilation, thermal stress The effects of burning or burning particles, which ultimately drip from the sample, ensure that these test conditions are not significantly different from those in normal use. 4.3 Finished parts (optional) If the test does not use a complete finished product, the following methods can be selected unless otherwise specified in the relevant product standard. a) cut a piece from the part of the finished or assembled product that needs to be inspected; b) opening a small hole in the finished product to allow the glow wire to pass through; or c) Remove the parts to be inspected from the finished product and conduct separate tests. The product standardization committee shall specify in which the relevant product standard can be tested. Whenever possible, these product standards should be exhausted It is possible to reproduce the actual use environment and conditions. 4.4 Test Considerations and Limitations Related to Specimen Shape During the opening process, if the hole is too small, the test knot may be affected by the light-off of the surrounding object and/or the temperature of the top of the glow wire. fruit. Therefore, the holes should be large enough to have sufficient air supply for combustion. During the test, if any part of the equipment containing the sample is ignited by heat other than the glow wire, which affects the heating condition of the sample, This test is invalid. The glow flammability test method for finished products should not be used to test small parts. This is because small parts are not effective in avoiding heat loss (see IEC 60695-2-10) also does not meet the requirements for glow wire penetration. The following parts are considered widgets. a) each surface can be covered by a circle of 15mm diameter; or b) even if there are surfaces of a certain size (length, width, height) greater than 15 mm, these surfaces cannot cover the diameter at the same time. 8mm round. see picture 1. When checking a surface. a) ignore the protruding part of the surface; b) Ignore any holes or depressions up to 2 mm in size. Figure 1 widget 5 test device The test device is described in IEC 60695-2-10. In order to assess the possibility of flame spread, such as the possibility of flame spread due to burning or burning particles falling from the sample, The underlay specified in IEC 60695-2-10 is placed under the specimen, or the material or component normally placed around or under the specimen is placed in the test. Below the sample. The distance between the specimen and the layup representing the surrounding material or component should be equal to the actual distance at the end of use.
