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.

Fire Hazard Testing for Electric and Electronic Products –
Part 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.
The test procedure described in this standard is a common test procedure intended for the small- scale tests in which a standardized electrically heated wire is used as a source of ignition. It is a common part of the test procedures applied to end products and to solid electrical insulating materials or other solid combustible materials.
A detailed description of each particular test procedure is given in the respective standards IEC 60695-2-11, IEC 60695-2-12 and IEC 60695-2-13.
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 104:2010 and ISO/IEC Guide 51:1999.
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.
