Annotation of standard text IEC/TS 61244-2-ed.2.0 :

IEC TS 61244-2:2014, which is a technical specification, applies to procedures for predicting ageing of polymeric materials at low dose rates. The object is to present three methods which can be used to extrapolate data obtained from high dose rate experiments to the low dose rates typical of service conditions. The techniques described are methods which have been found to be useful for a range of elastomeric, thermoplastic and thermoset materials. This edition includes the following significant technical changes with respect to the previous edition: a) examples and background information moved to annexes; b) examples updated with more recent references. LIEC TS 61244-2:2014, qui est une specification technique, sapplique aux procedures de prevision du vieillissement des materiaux polymeres a faible debit de dose. Il sagit de presenter trois methodes qui peuvent etre utilisees pour extrapoler, a de faibles debits de dose typiques des conditions de service, des donnees obtenues a partir dexperiences a debit de dose eleve. Les techniques decrites dans les articles suivants sont des methodes qui se sont revelees utiles pour une gamme de materiaux elastomeres et thermoplastiques. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) exemples et informations de fond deplaces dans les annexes; b) exemples mis a jour avec les dernieres references.
