Annotation of standard text IEC 60212-ed.3.0 :
IEC 60212:2010 gives the accepted conditions of exposure time, temperature, atmospheric humidity and liquid immersion for use in testing solid electrical insulating materials. The range is sufficiently wide to enable suitable conditions to be selected so that either of the primary objects, set out below as a) and b), of conditioning can be achieved. These objectives aim to obtain greater reproducibility of test results by: a) partly counteracting the variations of the properties of the material due to the past history of the test specimens (often known as "normalizing", here called preconditioning), and b) ensuring uniformity of conditions during the testing. This standard is not intended to be applied for determining the influence of exposure to certain temperatures and humidity or immersions in liquids, on the properties of a material. Procedures pertaining to the effect of an environment on a material are given in various parts of IEC 60068. The significant technical changes with respect to the previous edition are as follows: - the scope and normative references have been updated and terms and definitions completely reviewed; - technical details in Table 2 have been aligned to todays usage. La CEI 60212:2010 indique les conditions normales de duree dexposition, de temperature, dhumidite atmospherique et dimmersion dans un liquide a observer pour les essais des materiaux isolants electriques solides. La gamme en est suffisamment etendue pour pouvoir satisfaire aux conditions a determiner pour atteindre soit lun soit lautre des buts premiers du conditionnement (voir a) et b) ci-dessous). Ces objectifs visent a obtenir une reproductibilite plus etendue des resultats dessai: a) en neutralisant partiellement les differences constatees sur les proprietes du materiau dues aux influences subies anterieurement par les eprouvettes (traitement souvent connu sous le nom "normalizing" en anglais et appele ici preconditionnement), et b) en assurant luniformite des conditions au cours des essais. La presente norme nest pas destinee a etre appliquee pour determiner linfluence de lexposition a un certain nombre de temperatures, de taux dhumidite ou dimmersions dans des liquides, sur les proprietes dun materiau. Les modalites concernant les effets dun environnement sur un materiau sont donnees dans les differentes parties de la CEI 60068. Les modifications techniques majeures par rapport a ledition precedente sont enumerees comme suit: - le domaine dapplication et les references normatives ont ete mises a jour et les termes et definitions completement revus; - les details techniques du Tableau 2 ont ete alignes sur lusage quil en est fait de nos jours.
