CHAPTER V

Instruments are divided into three accuracy classes as follows: 0,5; 1; 2. The manufacturer shall specify the measurement range, the ratio between the minimum net load on the weighing unit and the maximum capacity, and the minimum totalised load. The minimum totalised load Σ_(min) shall not be less than 800 d for class 0.5, 400 d for class 1, 200 d for class 2. Where d is the totalisation scale interval of the general totalisation device. Table 8 Accuracy class MPE for totalised load 0,5 ± 0,25 % 1 ± 0,5 % 2 ± 1,0 % The speed of the belt shall be specified by the manufacturer. For single-speed beltweighers, and variable-speed beltweighers having a manual speed setting control, the speed shall not vary by more than 5 % of the nominal value. The product shall not have a different speed than the speed of the belt. It shall not be possible to reset the general totalisation device to zero. The MPE due to influence factor, for a load not less than the Σ_(min), shall be 0,7 times the appropriate value specified in Table 8, rounded to the nearest totalisation scale interval (d). The critical change value due to a disturbance shall be 0,7 times the appropriate value specified in Table 8, for a load equal to Σ_(min), for the designated class of the beltweigher; rounded up to the next higher totalisation scale interval (d).
