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”.

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.
