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 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.

Essais relatifs aux risques du feu - Partie 2-12: Essais au fil incandescent/chauffant - Méthode d'essai d'indice d'inflammabilité au fil incandescent (GWFI) pour matériaux
La CEI 60695-2-12:2010 spécifie les détails de l'essai au fil incandescent quand il est appliqué à des éprouvettes d'essai de matériaux isolants électriques solides ou autres matériaux solides pour les essais d'inflammabilité dans le but de déterminer l'indice d'inflammabilité au fil incandescent (GWFI, glow-wire flammability index). Le GWFI est la température la plus élevée, déterminée durant cette procédure normalisée, à laquelle le matériau essayé; ne s'enflamme pas ou s'il s'enflamme, s'éteint dans les 30 s qui suivent le retrait du fil incandescent et n'est pas entièrement consumé, et gouttes en fusion, s'il y a lieu, n'enflamme pas le papier mousseline. Cette norme doit être utilisée conjointement avec la CEI 60695-2-10 et la CEI 60695-2-13. Cette deuxième édition inclut les prochains changements techniques significatifs par rapport à l'édition précédente: - modification du titre; - ajout d'une Introduction; - clarification du Domaine d'application; - extension de l'Article 2: Références normatives; - définitions ajoutées à l'Article 3; - révision de l'Article 4 pour alignement avec la série CEI 60695-11 afin d'introduire des lignes directrices concernant les programmes d'essai pour les variations des matériaux; - clarification de l'Article 8: Conditionnement (désormais Article 7); - suppression de l'Article 9 'Mesures initiales'; - extension de l'Article 10: Méthodes d'essai (désormais Article 8); - extension de l'Article 11: Observations et mesures (désormais Article 9); - clarification de l'Article 12: Evaluation des résultats de l'essai (désormais Article 10); - extension de l'Article 13: Rapport d'essai (désormais Article 11). Cette norme a le statut de publication fondamentale de sécurité, conformément au Guide CEI 104 et au Guide ISO/CEI 51.
Preskušanje požarne ogroženosti - 2-12. del: Preskusne metode z žarilno žico - Preskusna metoda za materiale: indeks vnetljivosti z žarilno žico (GWFI) (IEC 60695-2-12:2010)
Ta del IEC 60695 določa podrobnosti preskusa z žarilno žico, ki se uporablja za preskus vzorca trdnih električnih izolacijskih materialov ali trdnih materialov za preskušanje vnetljivosti, da se ugotovi indeks vnetljivosti z žarilno žico (GWFI). GWFI je najvišja temperatura, ugotovljena med tem standardiziranim postopkom, pri kateri se preskušani material:
a) ne vname ali, če se, ugasne v 30 sekundah po umiku žarilne žice ter se
ali ne v celoti porabi in
b) če se pojavi kapljajoča talina, se ovojno blago ne vname.
Ta preskusna metoda je preskus materialov, izveden na seriji standardnih preskusnih vzorcev. Pridobljeni podatki, skupaj s podatki preskusne metode temperature vžiga žarilne žice (GWIT) za materiale, IEC 60695-2-13, se lahko uporabijo v predizbirnem postopku v skladu z IEC 60695-1-30, da se presodi, ali materiali lahko izpolnjujejo zahteve iz IEC 60695-2-11. OPOMBA Kot posledica izvajanja ocene požarne ogroženosti primerno zaporedje predizbirnih preskusov vnetljivosti in vžiga lahko omogoči zmanjševanje preskušanja končnega proizvoda. Ta osnovna varnostna publikacija je namenjena temu, da jo uporabljajo tehnični odbori pri pripravi standardov v skladu z načeli, opredeljenimi v IEC Guide 104 in ISO/IEC Guide 51. Ena od odgovornosti tehničnega odbora je, če je to primerno, uporabiti temeljne varnostne publikacije pri pripravi svojih publikacij. Zahteve, preskusne metode ali preskusni pogoji te temeljne varnostne publikacije se ne uporabljajo, razen če se ustrezne publikacije nanje izrecno sklicujejo ali jih vključujejo.

Glow-wire flammability index (GWFI) test method for materials
FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No l
