Pattern Approval

The Weights And Measures Act 1972 provides the legal basis for examining and approving patterns/designs of measuring instruments suitable for use for trade and other legal purposes.

Examination
  1. Assesment of the documentation.
  2. Assesment of the operation of the instrument against requirements (which are usually based on international recommendations published by OIML).
  3. Performance testing to ensure that the instrument performs as intended (i.e to within allowable maximum permissible errors) over a range of environmental and usage conditions specified in the requirements.
