introduction
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. How to achieve IEC 60695-1-10 and IEC 60695-1-11 developed by IEC /TC89 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. This section describes the small-scale test methods performed on materials used in electrical equipment. The 50W test flame is used as the ignition source. This section The specified classification method can be used for quality assurance, pre-selection of product parts and materials, or to verify the minimum level of combustion required for the materials used in the finished product. This test method cannot be used alone to describe or assess the risk of fire or fire of materials, products or components under actual fire conditions. However, the results of this test can be used as an element of a fire risk assessment that takes into account all factors, the fire risk assessment and a specific end use The risk assessment of the way is related.
This section may involve hazardous materials, operations, and equipment. Its purpose is not to solve all the security issues related to it. question. Before using this section, users of this section should establish appropriate safety and health measures and determine their applicability and limitations. Electrical and electronic products fire hazard test
Part 16. Test flame
50W horizontal and vertical flame test method
1 Scope
This part of GB/T 5169 specifies small-scale laboratory tests for comparing the combustion properties of different materials used in electrical and electronic products. Procedure, in which the strip sample is placed horizontally or vertically and exposed to a small flame with a nominal power of 50 W. Test method Used to determine the linear burning rate or self-extinguishing property of the material. The test methods in this section are applicable to solid materials and foams having an apparent density of not less than 250 kg/m3 as determined by the method of ISO 845. plastic.
This section gives two test methods. Method A is a horizontal burning test designed to measure the linear combustion of materials under specified test conditions. rate. Method B is a vertical burning test designed to measure the self-extinguishing ability of materials under specified test conditions. Note 1. ISO 9772 describes a test method for measuring the combustion characteristics of materials for materials with an apparent density of less than or equal to 250 kg/m3. ISO 9773 describes a test method for measuring the burning properties of materials, which is suitable for use in the use of method B of this part, because thin will produce distortion and / Or the material that burns to the fixture.
The classification methods specified in the test methods described in this section (see 8.4 and 9.4) can be used for quality assurance, pre-selection of product constituent materials, or Verify the minimum level of combustion required for the material used in the finished product. Note 2. The pre-selection guide can be found in IEC 60695-1-30.
This section is intended to prepare standards for the Product Standards Committee in accordance with the principles set forth in IEC Guide 104 and ISO /IEC Guide 51. One of the tasks of the Product Standards Committee is to use this series of standards wherever applicable. Unless relevant Special mention or list, otherwise the requirements, test methods or test conditions of this section will not apply. 2 Normative references
