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 Chinese documents that are consistent with the normatively referenced
international documents in this Part are as follows.

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.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO
13943.2008 and IEC 60695-4, some of which are reproduced below for the
user’s convenience, as well as the following apply.
4 Principle
A rectangular bar-shaped test specimen is supported horizontally or vertically
by one end and the free end is exposed to a specified test flame. The burning
behaviour of the horizontally supported bar under specific test conditions is
assessed by measuring the linear burning rate.
5 Significance of the fire tests
Results obtained in accordance with this Part shall not be used solely to
describe or appraise the fire hazard presented by a particular material under
actual fire conditions.
6 Apparatus
The laboratory burner shall conform to IEC 60695-11-4.
The measuring scale shall be graduated in millimetres (mm).
The pads shall be made of absorbent cotton designated “100 % cotton” or “pure
cotton”.
7 Test specimens
Bar test specimens shall measure 125 mm ± 5 mm long by 13.0 mm ± 0.5 mm
wide, and shall be provided in at least the minimum and maximum thickness
for which the flame classification is under consideration (see Figure 4).
8 Test method A - Horizontal burning test
Three test specimens shall be tested. Each test specimen shall be marked with
two lines perpendicular to the longitudinal axis of the bar, 25 mm ± 1 mm and
100 mm ± 1 mm from the end that is to be exposed to the test flame.
9 Test method B - Vertical burning test
All test specimens shall be tested in a laboratory atmosphere of 15 °C to 35 °C
and 40 % to 75 % relative humidity.
