IEC 60695-11-10:2013 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. These test methods 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. 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. This second edition cancels and replaces the consolidated version of IEC 60695-11-10 published in 2003 and constitutes a technical revision. The main changes with respect to the first edition are listed below:
- Editorial changes have been made throughout the document for the purpose of aligning IEC 60695-11-10 with IEC 60695-11-20,
- Details on test specimen dimensions have been added to Clause 7,
- New Sublause 9.1.4 Conditioning of the cotton pad has been added,
- New Subclause 9.2.4 Evaluation of "burned to the holding clamp" has been added,
- New Annex C with examples of datasheets has been added,
- The Bibliography has been updated and references added.
This publication is to be read in conjunction with IEC 60695-11-4:2011.
