Fire hazard testing - Part 11-10: Test flames - 50 W horizontal and vertical flame test methods

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.

It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. This International Standard is to be used in conjunction with IEC 60695-11-4.

Key words: Test flames, Fire hazard, Fire test
