Overview
EN IEC 62053-21:2021/A11:2021 is a CLC/CENELEC amendment to the European adoption of IEC 62053‑21. It defines particular requirements for static (electronic) watt‑hour meters used to measure AC active energy in 50 Hz or 60 Hz networks. The amendment applies to type tests only and covers accuracy classes 0,5, 1 and 2. This harmonized document supports conformity with Directive 2014/30/EU (EMC) when cited in the Official Journal, and was prepared by CLC/TC 13 “Electrical energy measurement and control.”
Key Topics and Requirements
- Scope and applicability
- Static watt‑hour meters for AC active energy in 50/60 Hz networks.
- Applies exclusively to type testing of meters in accuracy classes 0.5, 1, 2.
- Accuracy classes
- Requirements reference the defined accuracy classes (0,5; 1; 2) for active energy measurement.
- Electromagnetic compatibility (EMC)
- Includes multiple immunity and disturbance tests referenced in Annex ZZ, providing a route to presume conformity with Directive 2014/30/EU. Notable EMC tests listed in the amendment:
- Radiated radio‑frequency electromagnetic field immunity (including related current tests)
- Electrical fast transient / burst immunity
- Immunity to conducted disturbances induced by radio‑frequency fields
- Conducted differential mode disturbances and signalling (2 kHz–150 kHz)
- Damped oscillatory wave immunity
- External static and power‑frequency magnetic field immunity
- Includes multiple immunity and disturbance tests referenced in Annex ZZ, providing a route to presume conformity with Directive 2014/30/EU. Notable EMC tests listed in the amendment:
- Power‑quality related tests
- Tests for harmonics, interharmonics and non‑sinusoidal waveforms in current and voltage circuits (e.g., 5th harmonic, interharmonics, odd/even harmonic conditions).
- Administrative and adoption details
- Amendment A11 modifies EN IEC 62053‑21:2021 and includes national implementation timelines and conformity notes.
Applications and Who Uses It
- Meter manufacturers - design verification and type approval testing for static AC active energy meters.
- Test laboratories - defining test programs and reporting for type tests and EMC immunity testing.
- Utilities and metering integrators - specifying procurement and ensuring meters meet accuracy and EMC expectations.
- Regulators and conformity assessment bodies - referencing harmonized clauses for presumption of conformity with EU EMC requirements.
- R&D teams - validating meter performance under real‑world distortion, harmonic and magnetic field conditions.
Related Standards
- Part of the IEC/EN 62053 series (electricity metering equipment - particular requirements).
- Linked to Directive 2014/30/EU (EMC) via Annex ZZ for presumption of conformity when cited in the Official Journal.
