Anotation

IEC 60684-3-212:2005 standard gives the requirements for four types of heat-shrinkable polyolefin sleevings suitable for use at temperatures up to 135 °C. Type A: flame retarded, shrink ratio 2:1, Type B: not flame retarded, shrink ratio 2:1, Type C: flame retarded, shrink ratio 3:1, Type D: not flame retarded shrink ratio 3:1. This second edition cancels and replaces the first edition published in 1998, and constitutes a technical revision. This edition includes the following significant changes with regards to the previous edition: Replacement of the thermal endurance test method according to IEC 60216 with a long term ageing test, i.e. 3 000 h at the recommended maximum temperature found suitable for use, to provide safe thermal test data within a workable time scale. Key words: heat-shrinkable polyolefin sleevings LIEC 60684-3-212:2005 donne les exigences pour quatre types de gaines thermoretractables en polyolefine adaptees a une utilisation a des temperatures allant jusqua 135 °C. Type A: retardatrices de flamme, rapport de retreint 2:1, Type B: non retardatrices de flamme, rapport de retreint 2:1, Type C: retardatrices de flamme, rapport de retreint 3:1, Type D: non retardatrices de flamme, rapport de retreint 3:1. Cette deuxieme edition annule et remplace la premiere edition publiee en 1998 et constitue une revision technique. Cette edition comprend les modifications significatives suivantes par rapport a ledition precedente: Remplacement de la methode dessai dendurance thermique conformement a la CEI 60216 par un essai de vieillissement de longue duree, cest-a-dire 3 000 h a la temperature maximale recommandee pour un usage adapte, en vue de fournir des donnees dessai thermiques dans une echelle de temps exploitable.
