Within a scientific collaboration, statistical verification procedures for a qualification procedure in legal metrology are examined. To qualify utility meters for the efficient sampling procedure according to section 35 of the Measures and Verification Ordinance in Germany (see section 4.3 in GM-VA SPV), statistical hypothesis tests are selected and adapted to detect violations of the Normal distribution and of a small limiting failure rate. In addition, sample sizes are recommended for these tests.
