In a major Ease of Doing Business (EoDB) initiative, the Department of Consumer Affairs has amended the Legal Metrology (General) Rules, 2011 to simplify the verification process for high-capacity weighing instruments such as weighbridges and industrial scales.
The amendment introduces a scientific, repeatability-based verification method. It significantly reduces the quantity of standard reference weights required during verification while maintaining accuracy and reliability.
What Has Changed?
Previously, weighing instruments with a maximum capacity of 1 tonne or more had to be verified using standard reference weights equal to at least 50% of the instrument’s maximum capacity, or 1 tonne, whichever was greater.
≥ 50%
Standard weights of at least 50% of maximum capacity, or 1 tonne, whichever is greater.
20%
Standard weights of 20% of maximum capacity before substitution with constant loads, if the instrument passes the repeatability test.
Example: verifying a 50-tonne weighbridge earlier meant transporting 25 tonnes of calibrated standard weights, which was time-consuming and expensive.
Under the amended rules, a weighing instrument that passes a repeatability test, which confirms that it consistently produces accurate readings, needs standard weights equal to only 20% of its maximum capacity.
Why This Matters
The amendment is expected to benefit:
- Logistics companies and warehouses operating weighbridges
- Manufacturing and industrial facilities using high-capacity weighing instruments
- Weighbridge operators conducting periodic Legal Metrology verification
By reducing the quantity of standard weights required, businesses can expect:
- Lower transportation and handling costs
- Faster verification processes
- Reduced operational downtime
- Lower overall compliance costs
The Department has stated that the revised procedure maintains the prescribed standards of verification accuracy while making the process more efficient and practical.
A Step Towards Ease of Doing Business
The reform rests on internationally accepted metrological principles, under which the repeatability test establishes the consistency and stability of the weighing instrument before the requirement for standard weights is reduced.
The amendment reflects the Government’s continued effort to modernise India’s Legal Metrology framework through science-based, evidence-driven reforms that reduce regulatory burden while maintaining consumer protection and measurement accuracy.
