Annotation of standard text IEC 60120-ed.4.0 :
IEC 60120:2020 define the dimensions of a series of standard ball and socket couplings using the standard locking devices (see IEC 60372) in order to permit the assembly of insulators or metal fittings supplied by different manufacturers. This document applies to string insulator units of the cap and pin and long rod types and their associated metal fittings. For the pin ball and the socket, dimensions apply to the finished product after any surface treatment. Extreme positions of the pin ball in the socket are given in annex. Typical examples of gauges for checking the dimensions of pin balls and sockets are given in annex. l’IEC 60120:2020 definir les dimensions d’une serie d’assemblages a rotule normalises utilisant les dispositifs de verrouillage normalises (voir l’IEC 60372) afin de permettre l’assemblage d’isolateurs ou d’accessoires metalliques fournis par differents fabricants. Le present document s’applique aux elements de chaines d’isolateurs du type a capot, et tige et du type a long fut et aux accessoires metalliques qui leur sont associes. Les dimensions de la tige a rotule et du logement s’appliquent au produit fini apres tout traitement de surface. Les positions extremes de la tige a rotule dans le logement sont presentees en annexe. Des exemples types de calibres utilises pour verifier les dimensions des tiges a rotules et des logements sont presentes en annexe.
