Legal Metrology Rules Amended for High-Capacity Weighing Instruments

Key Details

• For instruments with capacity of one tonne and above, the standard-weight requirement before substitution with constant loads has been reduced from 50% to 20% of maximum capacity, subject to a successful repeatability test.
• The change is intended to lower transport and handling costs while preserving verification accuracy.
• A repeatability test checks whether an instrument gives consistent readings under the same conditions.
