I’ve already assured my meter or display, do I have to test it again?

Once a device has been assured and registered on the Device Assurance Register (DAR), then it does not need to be tested again unless in the follow scenarios:

• The testing or technical baselines have been updated and the manufacturer chooses to re-test against the changes;
• A device has been mistakenly added onto the DAR, for example: it is found that the assurance process was not followed correctly or if the information provided during testing was incorrect;
• The device has been Partially Assured and further testing is required to become Fully Assured; or
• The device has been awarded Partial Assurance with tolerated issues, following which an exemption form can be submitted to the Test House for retesting.
