This part of IEC 62058 specifies particular requirements for acceptance inspection of newly manufactured direct connected or transformer operated static meters for active energy (classes 0,2 S, 0,5 S, 1 and 2) delivered in lots in quantities above 50. The method of acceptance of smaller lots should be agreed upon by the manufacturer and the customer. The process described herein is primarily intended for acceptance inspection between the manufacturer and the purchaser. This European standard applies to meters of accuracy classes 0,2 S, 0,5 S, 1 and 2, as well as to meters of class indexes A, B and C.
