IEC 60695-2-12 Ed. 2.1 b:2014

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+A1:2014 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.   This consolidated version consists of the second edition (2010)  and its amendment 1 (2014). Therefore, no need to order amendment in addition to this publication.
