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.
This publication is to be read in conjunction with IEC 60695-11-4:2011.

IEC 60695-11-20:2015(Main)
Fire hazard testing - Part 11-20: Test flames - 500 W flame test method

IEC 60695-11-20:2015 describes a test method consisting of two small-scale laboratory test procedures which is intended to compare the burning behaviour of different materials used in electrotechnical products. Vertically oriented bar specimens or horizontally oriented plate test specimens are exposed to a small flame ignition source with a nominal thermal power of 500 W. The test method uses two test specimen configurations to classify material performance. Rectangular bar-shaped test specimens are used to assess ignitability and burning behaviour, and square plate test specimens are used to assess the resistance of the test specimen to burn-through, as defined in 8.3.3. This test method only applies to materials that have been classified as V-0 or V-1 according to IEC 60695-11-10. This test method is only applicable to solid and cellular materials that have an apparent density of more than 250 kg/m3, determined in accordance with ISO 845. The method does not apply to materials that shrink away from the applied flame without igniting due to their thinness. The test method described provides classifications which may be used for quality assurance, the pre-selection of component materials of products, or to verify the required minimum flammability classification of materials used in end products. If used for pre-selection, then positive results shall be obtained at a test specimen thickness which equals the smallest thickness used in the product application. The results obtained provide some information about the behaviour of materials in service, but cannot by themselves assure safe performance in service. This second edition cancels and replaces the consolidated version of IEC 60695-11-20 published in 2003. This edition constitutes a technical revision. The main changes with respect to the first edition are as follows:
- The Part title has been modified to the singular - 500 W flame test method;
- Editorial changes have been made throughout the document for the purpose of aligning IEC 60695-11-10 with IEC 60695-11-20;
- The Introduction has been modified to clarify the description of the test method;
- The Scope has been modified for clarification;
- All occurrences of the term "fixture" have been deleted from the document;
- Preferred thickness values have been added to 7.2 and 7.3;
- 7.4.4: 'Thickness measurement' is now numbered 7.5 to which a new Table 1 - Thickness tolerances has been added;
- New Subclause 8.1.4 'Conditioning of the cotton pad' has been added;
- 8.2.3 clarifies the application of the test flame to distorted specimens;
- Explanatory notes have been added to Figures 5 and 6 and the Bibliography has been updated and references added. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with IEC Guide 104 and ISO/IEC Guide 51.
