The Centre has amended legal metrology rules to allow government-approved testing centres to verify hydrogen, LPG, LNG, and CNG fuel dispensers. The move aims to improve efficiency and support the growing adoption of cleaner fuels. Verification fees have been set at ₹5,000 per nozzle for petrol and diesel dispensers, and ₹10,000 per nozzle for CNG, LPG, LNG, and hydrogen dispensers.
