This Part is Part 16 of GB/T 5169. This Part was drafted in accordance with the rules given in GB/T 1.1-2009. This Part replaces GB/T 5169.16-2008 “Fire hazard testing for electric and electronic products - Part 16: Test flames - 50 W horizontal and vertical flame test methods”. Compared with GB/T 5169.16-2008, the main technical changes are as follows: - MODIFY the clause of normative references (see Clause 2 of this Part, Clause 2 of 2008 edition); - MODIFY part contents of terms and definitions (see Clause 3 of this Part, Clause 3 of 2008 edition); - MODIFY the arrangement of “Test specimens” “Test method A” and “Test method B” clauses to make the structure clearer (see Clause 7, Clause 8 and Clause 9 of this Part, Clause 7, Clause 8 and Clause 9 of 2008 edition); - ADD the criteria for “burned to the holding clamp” (see 9.2.4); - DELETE the figure of “Burner/operator/test specimen orientation” (Figure 6 of 2008 edition); - ADD 7 figures, i.e. “Clearance gauge”, “Flame application”, “Flame application when there are molten drops”, “HB specimen gauge (example)”, “V specimen gauge (example)”, “Flame front position not classified as ‘burned to the holding clamp’”, “Flame front position classified as ‘burned to the holding clamp’” (Figures 6, 7, 8, 9, 9, 10, 11 and 12). This Part uses the translation method to identical to IEC 60695-11-10:2013 “Fire hazard testing - Part 11-10: Test flames - 50 W horizontal and vertical flame test methods”.

The previous released versions replaced by this Part are as follows: - GB/T 5169.16-002, GB/T 5169.16-2008. Fire hazard testing for electric and electronic products - Part 16: Test flames - 50 W horizontal and vertical flame test methods 1 Scope This Part of GB/T 5169 specifies small-scale laboratory test procedures intended to compare the burning behaviour of different materials used in electrotechnical products when vertically or horizontally oriented test bar specimens are exposed to a small flame ignition source with a nominal thermal power of 50 W. These test methods determine either the linear burning rate or the self-extinguishing properties of materials. The test methods of this Part are applicable to solid and cellular materials that have an apparent density of more than 250 kg/m3, determined in accordance with ISO 845. Two test methods are described in this Part. Method A is a horizontal burning test and is intended to determine the linear burning rate of materials under specific test conditions. Method B is a vertical burning test and is intended to determine whether materials self-extinguish under specific test conditions. NOTE 1: ISO 9772 describes a test method for the determination of the burning characteristics to be used for materials with an apparent density of 250 kg/m3 or less. ISO 9773 describes a test method for the determination of the burning behaviour to be used for materials that due to their thinness, either distort and/or are burned up to the holding clamp using Method B of this Part. The test methods described in this Part provide classifications (see 8.4 and 9.4), which may be used for quality assurance, the pre-selection of component materials of products, or to verify the required minimum flammability classification of materials used in end products. NOTE 2: Guidance on pre-selection is given in IEC 60695-1-30. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications. 2 Normative references The following referenced documents are indispensable for the application of this document.
