Annotation of standard text IEC 60695-2-12-ed.3.0 :
IEC 60695-2-12:2021 is available as IEC 60695-2-12:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. 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. IEC 60695-2-12:2021 est disponible sous forme de IEC 60695-2-12:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente. IEC 60695-2-12:2021 decrit les informations detaillees de l’essai au fil incandescent destine a etre applique a des eprouvettes d’essai de materiaux isolants electriques solides ou autres materiaux solides pour les essais d’inflammabilite dans le but de determiner l’indice d’inflammabilite au fil incandescent (GWFI, glow-wire flammability index). Le GWFI est la temperature la plus elevee, determinee durant cette procedure normalisee, a laquelle le materiau en essai ne s’enflamme pas ou s’il s’enflamme, s’eteint dans les 30 s qui suivent le retrait du fil incandescent et n’est pas entierement consume; et des gouttes en fusion, s’il y a lieu, n’enflamment pas le papier mousseline. Cette methode d’essai est un essai de materiaux execute sur une serie d’eprouvettes dessai normalisees. Les donnees obtenues, ainsi que les donnees issues de la methode d’essai de temperature d’allumabilite au fil incandescent (GWIT, glow-wire ignition temperature) pour materiaux, IEC 60695-2-13, peuvent alors etre utilisees dans un processus de preselection conformement a l’IEC 60695 1 30 [4] pour estimer laptitude des materiaux a satisfaire aux exigences de l’IEC 60695 2 11. La presente publication fondamentale de securite, fondee sur la ou les methodes dessai de securite, est essentiellement destinee a etre utilisee par les comites d’etudes dans le cadre de l’elaboration de publications de securite conformement aux principes etablis dans le Guide IEC 104 et le Guide ISO/IEC 51. L’une des responsabilites d’un comite d’etudes consiste, le cas echeant, a utiliser les publications fondamentales de securite dans le cadre de l’elaboration de ses publications. Cette norme doit etre utilisee conjointement avec l’IEC 60695-2-10. Cette troisieme edition annule et remplace la deuxieme edition parue en 2010 et lAmendement 1:2014. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) ajout a l’Article 3 de nouveaux termes et definitions, ayant rapport aux moments et durees, applicables a la methode dessai.
