# The Non-automatic Weighing Instruments (EEC Requirements) Regulations 1995, Paragraph 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.
