Notification
 IS 13779:1999 (AC static watt-hour meters, class 1 & 2) is covered under the Electrical Wires, Cables, Appliances and Protection Devices and Accessories (Quality Control) Order, 2003, notified via S.O. 189(E) dated 17 February 2003, with amendments in 2004, 2005, 2009 and 2010.
Enforcement Timeline
 The QCO became effective on 17 February 2003 (date of publication). All meters in scope must conform to IS 13779 and carry a valid BIS licence from that date.
Overview
 The standard specifies requirements for AC static watt-hour meters of class 1 and class 2 accuracy, intended for billing applications in residential, commercial and industrial networks. It covers meter construction, accuracy, performance testing and safety provisions.
Objective & Scope
 The primary aim is to ensure accurate billing and consumer protection, prevent energy theft/meter tampering, and ensure long-term reliability of static electronic energy meters used by utilities.
Products Covered
 Single-phase and three-phase AC static watt-hour meters of class 1 and 2, including direct connected and CT/VT-operated models.
Exemptions Provided
 Export-only consignments are exempt under the QCO proviso, subject to government approval.
Industries Impacted
 This affects meter manufacturers, DISCOMs, state utilities, EPC contractors, calibration labs, importers and system integrators supplying billing meters.
Mandatory Compliance Requirements
 Manufacturers and importers must obtain a BIS Standard Mark licence under Scheme-I; products must be tested at BIS-recognised labs and carry the ISI mark on the nameplate and packaging.
Next Steps for Stakeholders
 Firms must apply to BIS, arrange type testing, implement QA systems, conduct batch/routine testing, and ensure packaging/marking complies with IS requirements. Procurement agencies should revise tender conditions to accept only ISI-marked meters.
Legal Provisions, Enforcement & Penalties
 The Order is enforced under the BIS Act, 2016. Contraventions (e.g., manufacture/sale of non-conforming or non-marked goods) attract actions including search/seizure and prosecution. Section 29(3) prescribes penalties up to two years’ imprisonment and fines (with specified minimums and escalation for repeat offences).Â
Conclusion
 Since 17 February 2003, IS 13779 static energy meters must be BIS certified. This ensures standardised accuracy, billing reliability, and legal compliance in the Indian market.
