Annotation of standard text IEC/TS 60349-3-ed.2.0 :

IEC/TS 60349-3:2010 applies to machines complying with IEC 60349-2. The losses supplied at the fundamental frequency cannot be measured directly and so are derived from measurement of the fundamental frequency load current and the fundamental frequency no-load power input. The main technical changes with regard to the previous edition are corrections in some formulas in 3.2.1.2 and in Table A.2. La CEI/TS 60349-3:2010 sapplique aux machines satisfaisant a la CEI 60349-2. Les pertes fournies a la frequence fondamentale ne peuvent pas etre mesurees directement et par suite elles sont deduites des mesures du courant en charge et de la puissance dentree a vide a la frequence fondamentale. Les principaux changements techniques par rapport a ledition precedente sont des corrections dans certaines formules de 3.2.1.2 et dans le Tableau A.2.
