Each contribution is a limit ±a with a rectangular distribution; the standard uncertainty is a divided by the square root of 3. The contributions are added in quadrature, the expanded uncertainty uses a coverage factor of 2 (about 95 %). The limits are specifications from the data sheet and the test record and can be changed here.
