Annex A - Tolerances for Test Equipment
Tolerances for Test Equipment
Weights used for the calibration of equipment covered by this code shall be adjusted to the tolerances specified for Class M3 weights as defined in OIML Recommendation R111. This is equivalent to weights known as “traders weights” under the current UK Weights and Measures legislation. The use of such weights will ensure that the maximum error on the weights used for the calibration does not exceed 0.25% of the applied load.
Test equipment used for calibration purposes (e.g. hydraulic loading devices) shall be calibrated and adjusted such that the maximum error on the equipment does not exceed 1 scale division or 0.25% of the applied load, whichever is the greater.
