BIS IS:13779 Certification - What It Is and Why You Should Only Buy Certified Meters

IS:13779 is the Indian Standard for Static Electricity Meters - mandatory for all energy meters sold in India for sub-metering. BIS certification means the manufacturer's specific meter models have been tested at a NABL-accredited laboratory and found compliant.

Why Uncertified Meters Are a Risk

Accuracy risk: uncertified meters often run 3-8% fast or slow - significant over-billing in a large society. Legal risk: uncertified meters are indefensible in a regulatory audit. Warranty risk: no meaningful warranty coverage.

How to Verify
