This Part is Part 10 of GB/T 5169.
This Part was drafted as per the rules specified in GB/T 1.1-2009.
This Part replaced GB/T 5169.10-2006 Fire Hazard Testing for Electric and Electronic
Products - Part 10.Glow/Hot-Wire Based Test Methods - Glow-Wire Apparatus and Common
Test Procedure. Compared with GB/T 5169.10-2006, the major technical changes of this Part
are as follows.
--- Move the content of "Summary of Test Equipment and General Test Methods" to the
Scope (see Clause 1 of this Edition; Clause 4 of 2006 Edition);
--- Add some terms and definitions (see Clause 3 of this Edition);
--- Add provisions for new glow wire annealing treatment (see 4.1 of this Edition; 5.1 of
2006 Edition);
--- Revise the description of the provisions of the test chamber (see 4.5 of this Edition; 5.4
of 2006 Edition);
--- Increase requirements for timing devices (see 4.6 of this Edition);
--- Revise the standard for replacing the glow wire; CHANGE FROM when the Dimension-
A "reduces to 90% of the initial reading", it shall be replaced TO. when it "reduces to
97.5% of the reading before the initial test" (see 5.1 of this Edition; 6.1 of 2006 Edition);
--- Add Annex A "Equipment Manufacturers and Suppliers " (see Annex A of this Edition);
--- Add Annex B "Guidance on ‘Ignition’ and ‘Flaming’ Observations" (see Annex B of this
Edition);
--- Add Annex C "Guidance on the Verification Procedure of the Glow-Wire Temperature
Measuring System by the Heating Current" (see Annex C of this Edition).
This Part used translation method to equivalently adopt IEC 60695-2-10.2013 Fire Hazard
Testing – Part 2-10.Glowing/Hot-Wire Based Test Methods – Glow-Wire Apparatus and
Common Test Procedure.

1 Scope
This Part of GB/T 5169 specifies the glow-wire apparatus and common test procedure to
simulate the effects of thermal stresses which may be produced by heat sources such as glowing
elements or overloaded resistors, for short periods, in order to assess the fire hazard by a
simulation technique.
2 Normative References
The following documents are essential to the application of this document. For the dated
documents, only the versions with the dates indicated are applicable to this document; for the
undated documents, only the latest version (including all the amendments) is applicable to this
document.
3 Terms and Definitions
For the purposes of this document, the terms and definitions given in ISO 13943.2008, some
of which are reproduced below for the user’s convenience, as well as the following apply.
Test that measures behavior of a fire or exposes an item to the effects of a fire.
4 Description of the Test Apparatus
The temperature of the tip of the glow-wire shall be measured by a class 1 (see IEC 60584-2)
mineral-insulated metal-sheathed fine-wire thermocouple with an insulated junction.
The apparatus shall be operated in a draught-free environment having sufficient volume such
that.
5 Verification of the Apparatus
The temperature measuring system described in 4.3 shall be verified periodically using the
procedure described below.
6 Conditioning
Before testing, the wooden board and wrapping tissue shall be stored for a minimum of 24 h in
an atmosphere having a temperature between 15 °C and 35 °C and a relative humidity between
45 % and 75 %.
7 Common Test Procedure
The tip of the glow-wire is then brought smoothly into contact with the test specimen for a
duration of 30 s ± 1 s. An approximate rate of approach and withdrawal of 10 mm/s to 25 mm/s
has been found to be satisfactory. However, the rate of approach shall be reduced to near zero
upon contact to avoid impact forces exceeding 1.05 N.
