4.  Accuracy

4.1. On implementation of the procedures laid down in Article 8, the error of indication shall not exceed the maximum permissible error of indication as shown in Table 3. In case of digital indication the error of indication shall be corrected for the rounding error.

• The maximum permissible errors apply to the net and tare value for all possible loads, excluded preset tare values.

  Maximum permissible errors

  Load				Maximum permissible error
  Class I	Class II	Class III	Class IIII
  0 ≤m≤ 50 000 e	0 ≤m≤ 5 000 e	0 ≤m≤ 500 e	0 ≤m≤ 50 e	± 0,5 e
  50 000 e <m≤ 200 000 e	5 00 e <m≤ 20 000 e	500 e <m≤ 2 000 e	50 e <m≤ 200 e	± 1,0 e
  200 00 e <m	20 000 e <m≤ 100 000 e	2 000 e <m≤ 10 000 e	200 e <m≤ 1 00 e	± 1,5 e

4.2. The maximum permissible errors in service are twice the maximum permissible errors fixed in section 4.1.
