How to ensure that your EMVA1288 equipment is compliant

Up to version 3.1 of the standard, the developers of a test equipment must self-certify. There is no verification of capabilities of the test equipment or the correctness of the results. Even though version 3.1 adds some more requirements regarding the data that must be produced and published and the formatting of the report, there are still no specific requirements on certification.

Version 3.2 of the standard, now under development, will start to change the game, as a strict procedure will be published on how to certify that the software performing the calculations is correct. In order to do so, three published reference sets will need to be processed and compared with the expected results. It will be mandatory to have at least 10 significant digits correct on all measurements.

Version 3.3 will bring even more requirements by defining methods to validate the hardware of the equipment. Of course hardware validation is much more difficult, especially regarding absolute calibration, and also because the validation is not deterministic (measurement noise is always present) and will therefore not require 10 significant digits. The methods proposed will address the correctness of the results, the repeatability of the measurement and the reproduceability of the measurement.

Since validating a test equipment is not an easy task and may require significant experience with EMVA1288, Aphesa now also proposes a system certification service.
