IEC 61515-ed.2.0

Annotation of standard text IEC 61515-ed.2.0 :

IEC 61515:2016 establishes the requirements for simplex, duplex and triplex mineral-insulated metal-sheathed thermocouple cables and thermocouples, which are intended for use in general industrial applications. The abbreviation MIMS (for "mineral-insulated metal-sheathed") will be used hereafter. It covers thermocouple cables and thermocouples with only base-metal conductors of Types T, J, E, K and N. The specifications in this standard apply to new thermocouple cables and thermocouple units as delivered to the user. They do not apply to the product after use. This second edition cancels and replaces the first edition published in 1995. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Duplex and triplex are standardized. - Specification of insulation resistance is revised so that the user can choose the best product to fit for the purpose. - "Table 2 Recommended maximum operating temperatures" in the previous version is expanded significantly including newly developed sheath material and it is moved to Annex C. - Test items and their methods are expanded and a guide table (Table 4) is added for userfriendliness. LIEC 61515:2016 etablit les exigences relatives aux cables et couples thermoelectriques a isolation minerale dits "chemises" de types simplex, duplex et triplex, qui sont destines a des applications industrielles generales. Labreviation MIMS (Mineral Insulated Metal-Sheathed) sera utilisee ci-apres. Elle concerne les cables et couples thermoelectriques a conducteurs a base de metaux usuels de types T, J, E, K et N uniquement. Les specifications definies dans la presente norme sappliquent aux cables et ensembles de couples thermoelectriques neufs livres a lutilisateur. Elles ne sappliquent pas au produit usage. Cette deuxieme edition annule et remplace la premiere edition parue en 1995. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - Les types duplex et triplex ont ete normalises. - La specification de la resistance disolement a ete revisee pour permettre a lutilisateur de choisir le produit le mieux adapte a lemploi. - Le Tableau 2 "Temperatures de fonctionnement maximales recommandees" de la version precedente a ete considerablement developpe et couvre notamment les materiaux de gainage nouvellement developpes. Il a ete deplace a lAnnexe C. - Les types dessai et leurs methodes ont ete developpes, et un tableau indicatif (Tableau 4) a ete ajoute pour faciliter la comprehension de lutilisateur.
