Description

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 standard is to be used in conjunction with IEC 60695-2-10 and IEC 60695-2-13. 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 standard has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51.

This publication is to be read in conjunction with IEC 60695-2-10:2000 and IEC 60695-2-13:2010.
