GB/T 5169.17-2017Fire hazard testing for electric and electronic products -- Part 17: Test flames--500 W flame test method (English PDF)

GB/T 5169.17-2017 is the English-translated version of 电工电子产品着火危险试验 第17部分：试验火焰 500W火焰试验方法.

GB/T 5169.17-2017 is the Chinese standard "Fire hazard testing for electric and electronic products -- Part 17: Test flames--500 W flame test method".

Its scope clause reads: This part of GB/T 5169 describes a test method consisting of two small-scale test procedures aimed at comparing electrical and electronic The combustion characteristics of different materials in the product.

Expose vertically placed strips or horizontally placed slabs to nominal power 500W The small flame ignition source. The test method is to classify the material properties with two shapes of specimens.

Rectangular strips for evaluation The ignitability and flammability of the test specimens are determined, and square shaped test specimens are used to evaluate the burnthrough resistance of the test specimens, as described in 8.3.3.

This test The method is only applicable to materials that comply with IEC 60695-11-10 V-0 or V-1. This test method is only applicable to solid/microporous materials with an apparent density greater than 250kg/m3 determined according to ISO 845; not applicable The material that collapses because it is too thin to catch fire and does not ignite.

The grading method specified in this test method can be used for quality assurance, pre-selection of product part materials, or verification of the materials used in finished products.

Minimum combustion rating. If used for preselection, the thickness of the test specimen should be the same as the minimum thickness used for the application in order to obtain a true result.

Although the test results provide some properties of the plastic when it is used, it cannot be used to determine the safety performance of the material when it is used.

Note 1. See IEC 60695-1-30 for preselection guidelines. NOTE 2 The test results are influenced by the material additives and properties such as colorants, fillers and flame retardants, the latter being anisotropic in direction and molecular weight.

This section is intended to be prepared by the product standard committee in accordance with the principles laid down in IEC Guide 104.2010 and ISO /IEC Guide 51.1999. standard.

One of the tasks of the Product Standards Committee is to use this series of standards where applicable. Unless relevant It is specifically mentioned or listed, otherwise the requirements, test methods or test conditions of this part will not apply.
