IEC 60695-11-5 Flammability Testing Equipment Needle Flame Test

IEC 60695-11-5 Flammability Testing Equipment Needle Flame Test

Standard:

IEC 60695-11-5 Fire hazard testing - Part 11-5: Test flames - Needle-flame test method - Apparatus, confirmatory test arrangement and guidance

Application:

This part of IEC 60695 specifies a needle-flame test to simulate the effect of a small flame which may result from fault conditions, in order to assess the fire hazard by a simulation technique. The results of this test may be used as elements of a fire hazard assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

Summary of the test method:
The test specimen is arranged in a vertical position over tissue paper. A propane gas flame is applied to the edge as well as to the flat surface. The burning time, flammability and severity (exposure time) are determined for this flame application. The test is usually performed on parts or selected areas of these parts.

Test sample:

It is applicable to electrotechnical equipment, its sub-assemblies and components and to solid electrical insulating materials or other combustible materials.

Parameters:
