GB/T 5169.5-2020 Fire hazard testing for electric and electronic products—Part 5: Test flames—Needle-flame test method—Apparatus, confirmatory test arrangement and guidance English
1 Scope
This part of GB/T 5169 specifies a needle-flame test to simulate the effect of a small flame which may result from fault conditions, in order to assess the fire hazard by a simulation technique. The results of this test may be used as elements of a fire hazard assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.
This part is applicable to electrotechnical equipment, its sub-assemblies and components and to solid electrical insulating materials or other combustible materials.
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.

3.1
combustible (adj)
capable of being ignited and burned
[ISO 13943:2008, definition 4.43]
3.2
draught-free environment
space in which the results of experiments are not significantly affected by the local air speed
Note: A qualitative example is a space in which a wax candle flame remains essentially undisturbed. Quantitative examples are small-scale fire tests in which a maximum air speed of 0.1m/s or 0.2m/s is sometimes specified.
[ISO 13943:2008, definition 4.70]
3.3
fire
(general) process of combustion characterized by the emission of heat and fire effluent and usually accompanied by smoke, flame, glowing or a combination thereof
Note: In the English language the term “fire” is used to designate three concepts, two of which, fire (3.4) and fire (3.5), relate to specific types of self-supporting combustion with different meanings and two of them are designated using two different terms in both French and German.
[ISO 13943:2008, definition 4.96]
3.4
fire
(controlled) self-supporting combustion that has been deliberately arranged to provide useful effects and is limited in its extent in time and space
[ISO 13943:2008, definition 4.97]
