Main content area

Pattern approval is where an impartial body examines the design of an instrument prototype against our national or international standards. This determines the measurement accuracy of the instrument and whether the instrument retains this accuracy under a range of environmental and operating conditions.

If your instrument passes the pattern approval process, we issue a certificate of approval.

How to apply

  1. Read the Approval and Certification Procedures for Measuring Instruments Suitable for Use for Trade and any Other Legal Purpose [630KB PDF] [675KB DOC].
  2. Review the pattern approval requirements and the pattern approval guidelines and procedures relevant to your instrument. 
  3. Collect all documents related to your instrument, including:
  • details of the instrument
  • model number
  • capacities
  • operator manuals
  • technical manuals
  • circuit diagrams
  • board layout diagrams
  • parts lists and mechanical overview (exploded views)
  • proposed sealing methods and nameplate layouts
  1. Complete and submit the Pattern approval application form.
  2. When we receive your application, we will confirm receipt and next steps.

Testing and assessment

After we receive your application, we either:

  • test and assess your instrument pattern
  • assess test results from other ISO 17025 accredited facilities with appropriate scope of accreditation 

See Pattern approval instrument testing and assessment to find out more.

Fees

The fees for pattern approval depends on the type of measuring instrument you need approved.

Our Pattern approval fee guide spreadsheet  provides the base rates for pattern approval.

  • Use the Fee level selection tab to pick your level and class of instrument.
  • Use the Fee estimate tab to see the tests performed and price for your level and class of instrument.

More complex instruments may take more time than the estimate in the guide.
