Fire hazard testing - Part 2-12: Glowing/hot-wire based test methods - Glow-wire flammability index (GWFI) test method for materials

IEC 60695-2-12:2021 specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for flammability testing to determine the glow-wire flammability index (GWFI). GWFI is the highest temperature, determined during this standardized procedure, at which the tested material does not ignite or, if it does, extinguishes within 30 s after removal of the glow-wire and is not totally consumed; and molten drips, if they occur, do not ignite the wrapping tissue. This test method is a materials test carried out on a series of standard test specimens. The data obtained, along with data from the glow-wire ignition temperature (GWIT) test method for materials, IEC 60695-2-13, can then be used in a preselection process in accordance with IEC 60695-1-30 [4] to judge the ability of materials to meet the requirements of IEC 60695-2-11. This basic safety publication focusing on safety test method(s) is primarily intended for use by technical committees in the preparation of safety publications in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. This publication is to be read in conjunction with IEC 60695-2-10. This third edition cancels and replaces the second edition published in 2010 and Amendment 1:2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) New terms and definitions with regards to times and durations have been added to Clause 3, with an effect on the application of the test method.

Fire hazard testing - Part 2-12: Glowing/hot-wire based test methods - Glow-wire flammability index (GWFI) test method for materials

IEC 60695-2-12:2010 specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for flammability testing to determine the glow-wire flammability index (GWFI). GWFI is the highest temperature, determined during this standardized procedure, at which the tested material; does not ignite or, if it does, extinguishes within 30 s after removal of the glow-wire and is not totally consumed, and molten drips, if they occur, do not ignite the wrapping tissue. This second edition includes the following significant technical changes from the previous edition: - modified title; - addition of an Introduction; - clarification of Scope; - expansion of Clause 2: Normative references; - definitions added to Clause 3; - revision of Clause 4 to alignment with the IEC 60695-11 series to introduce guidance on test programs for material variations; - clarification of Clause 8: Conditioning (now Clause 7); - deletion of Clause 9 "Initial measurements"; - expansion of Clause 10: Test procedures (now Clause 8); - expansion of Clause 11: Observation and measurement (now Clause 9); - clarification of Clause 12: Evaluation of test results (now Clause 10); - expansion of Clause 13: Test report (now Clause 11). This publication is to be read in conjunction with IEC 60695-2-10:2000 and IEC 60695-2-13:2010.
