Annotation of standard text IEC 60317-71-ed.2.0 :
IEC 60317-71:2020 specifies the requirements of polyester glass-fibre wound resin/varnish impregnated, bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 180. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified. The nominal conductor diameters are specified in IEC 60317-0-10:2017, Clause 4. This second edition cancels and replaces the first edition published in 2017. The document 55/1767/CDV, circulated to the National Committees as Amendment 1, led to the publication of this new edition. This edition includes the following significant technical changes with respect to the previous edition: - modification of the title; - revision to the Scope; - revision to 3.2.2. IEC 60317-71:2020 specifie les exigences relatives au fil de bobinage de section circulaire en cuivre nu ou emaille de grade 1 ou de grade 2, guipe de fibres de verre polyester impregnees de vernis ou de resine, dindice de temperature 180. NOTE Pour ce type de fil, lessai de choc thermique nest pas approprie et cest la raison pour laquelle il nest pas possible detablir une temperature de choc thermique. Par consequent, il n’est pas possible de specifier une classe fondee sur les exigences dindice de temperature et de temperature de choc thermique. Les diametres nominaux du conducteur sont specifies a lArticle 4 de lIEC 60317-0-10:2017. Cette deuxieme edition de lIEC 60317-71 annule et remplace la premiere edition parue en 2017. Le document 55/1767/CDV, circule comme Amendement 1 aupres des Comites nationaux de lIEC, a conduit a la publication de cette nouvelle edition. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - modification du titre; - revision du Domaine dapplication; - revision du 3.2.2.
