Calibration Procedure
Calibration of Weights: OIML Class
This procedure involves:
- the verification of an OIML weight for its compliance with the metrological and technical requirements of the OIML Recommendation 111; and
- its calibration with results in conventional mass by direct comparison using double substitution weighing. This technique includes the comparison of one weight with another of equal nominal value but with a higher OIML classification.
Calibration of Mass Standards: Free Nominal Values
This procedure applies to mass standards with free nominal values. The free nominal values are present beyond +/- 3 times of the selected class of OIML R111. This procedure involves the calibration of weights with results in conventional mass by direct comparison using double substitution weighing. This technique involves the comparison of one sample weight with a combination of up to four reference weights equal to or near the nominal value of the sample weight.
Calibration of Mass Standards: Non-OIML
This procedure applies to mass standards that are non-OIML and OIML weights but do not comply with the metrological and technical requirements of the OIML R111 It involves calibration with results in conventional mass by direct comparison using double substitution weighing. This technique involves the comparison of one weight with another of equal nominal value.
