Anotation

IEC 60372:2020 is applicable to locking devices used with ball and socket couplings of string insulator units and used with the corresponding metal fittings standardized in IEC 60120, when they are supplied separately.The object of this document is - to define the shapes and some standard dimensions for locking devices, - to define the test methods for locking devices, - to state the acceptance conditions for supply, - to give other dimensions for guidance of manufacturing only. This fourth edition cancels and replaces the third edition published in 1984. This edition includes the following significant technical changes with respect to the previous edition: a. Two new designated size of couplings, 36 and 40, were introduced; b. the relevant content of the 28B W-clip was deleted; c. Annex A is informative, Annex B is normative, Annex C is informative. l’IEC 60372:2020 est applicable aux dispositifs de verrouillage utilises avec les assemblages a rotule des elements de chaines disolateurs et utilises avec les accessoires metalliques correspondants normalises dans l’IEC 60120, lorsquils sont livres separement. Le present document a pour objet: - de definir les formes et certaines dimensions normalisees des dispositifs de verrouillage, - de definir les methodes dessai des dispositifs de verrouillage, - de fixer les conditions dacceptation dune fourniture, - de donner dautres dimensions, uniquement a titre de recommandation pour la fabrication. Cette quatrieme edition annule et remplace la troisieme edition parue en 1984. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a. Deux nouvelles tailles d’assemblages normalisees, 36 et 40, sont presentees; b. le contenu concernant lagrafe 28B a ete supprime; c.
