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)
This part of IEC 60695 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.
NOTE As an outcome of conducting a fire hazard assessment, an appropriate series of preselection flammability and ignition tests can allow a reduction of end product testing.
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.

Die Norm SIST EN IEC 60695-2-12:2022 behandelt die Brandgefahrprüfung und spezifiziert die Glow-Wire-Flammability-Index (GWFI) Testmethode für Materialien. Der Schwerpunkt dieser Norm liegt auf der Erprobung der Entflammbarkeit von festen elektrischen Isoliermaterialien oder anderen festen Materialien. Die vorliegende Norm ist von großer Bedeutung für die Sicherheitsbewertung, da sie detaillierte Vorgaben zur Durchführung des Glow-Wire-Tests enthält, der entscheidend für die Bestimmung des GWFI ist. Ein herausragendes Merkmal dieser Norm ist die klare Definition der Testprozedur. Der GWFI stellt die höchste Temperatur dar, bei der das getestete Material nicht entzündet oder, falls es dennoch zu einer Entzündung kommt, innerhalb von 30 Sekunden nach Entfernen des Glow-Wires erlischt und nicht vollständig verbrannt wird. Des Weiteren wird sichergestellt, dass eventuelle schmelzenden Tropfen, falls vorhanden, das umgebende Material nicht entzünden. Diese präzisen Vorgaben tragen wesentlich zur Sicherheit und Verlässlichkeit von Materialien bei, die im elektrischen und elektronischen Bereich verwendet werden. Die Norm bietet auch eine wertvolle Grundlage für die vorherige Auswahl von Materialien in Übereinstimmung mit der IEC-Norm 60695-1-30. Durch die Kombination der Ergebnisse des GWFI-Tests mit den Daten des Glow-Wire-Zündtemperatur-Tests (GWIT) gemäß IEC 60695-2-13 ermöglicht der eingesetzte Testansatz eine effektive Reduzierung der Prüfanforderungen für Endprodukte, was sowohl Zeit als auch Kosten spart. Die SIST EN IEC 60695-2-12:2022 Norm richtet sich primär an technische Ausschüsse, die Sicherheitsveröffentlichungen vorbereiten und dabei die im IEC Guide 104 und ISO/IEC Guide 51 festgelegten Prinzipien berücksichtigen. Das Engagement der technischen Ausschüsse, grundlegende Sicherheitsveröffentlichungen in der Erstellung ihrer Dokumente zu nutzen, hebt die Relevanz dieser Norm in der Sicherheitsprüfungslandschaft weiter hervor.
