IEC 60695-2-10-2000 pdf free.Fire hazard testing – Part 2-10: Glowing/hot-wire based test methods – Glow-wire apparatus and common test procedure.
This part of IEC 60695 specifies the glow-wire apparatus and common test procedure to simulate the effect 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 described in this standard is applicable to electrotechnical equipment, its subassemblies and components, and may also be applied to solid electrical insulating materials or other solid combustible materials.
One of the responsibilities of a technical committee is. wherever applicable, to make use of basic safety publications in the preparation of its publications.

3 Definitions
For the purposes of this part of IEC 60695. the definitions given in ISO/IEC 13943, as well as the following definition, apply.
test temperature and temperature of the glow-wire
temperature to which the tip of the glow-wire is heated and stabilized prior to any contact with the test specimen
4 Outline of the test apparatus and common test procedure
This part of IEC 60695 specifies the glow-wire apparatus and common test procedure as a fire test using a non-flame ignition source.
The glow-wire is a specified loop of resistance wire, which is electrically heated to a specified temperature. The tip of the glow-wire is brought into contact with a test specimen for a specific period of time and a range of observations and measurements made. dependant upon the particular test procedure.
A detailed description of each test procedure is given in IEC 60695-2-11, lEG 60695-2-12 and lEG 60695-2-13.
5 Description of the test apparatus
5.1 Glow-wIre
The glow-wire is made from nickel/chromium (80/20) wire, with an overall nominal diameter of 4 mm. The wire is formed into a loop as detailed in figure 1.
The glow-wire is heated by a simple electric circuit as shown in figure 2. There shall be no feedback mechanism or circuit to maintain the temperature.
Due to the high currents involved, it is essential that the electrical connections for the glow-wire are capable of carrying the current without affecting the performance or long-term stability of the circuit.IEC 60695-2-10 pdf download.
