IEC TS 62586-3:2025 Describes a procedure used for maintenance tests of individual power quality instruments. Users of these instruments need to ensure the conformity of the individual power quality instrument for stationary use with the requirements of IEC 62586‑1. This is achieved by periodic maintenance tests as defined in this document.

Overview

IEC TS 62586-3:2025 - Power quality measurement in power supply systems - Part 3: Maintenance tests, calibration - defines recommended procedures for periodic maintenance tests and the calibration of reference artifacts used when verifying individual power quality instruments. The Technical Specification supports users who must ensure that instruments used for stationary power quality measurement remain conformant with IEC 62586‑1 and with type testing performed under IEC 62586‑2. It also describes a calibration programme that maintains traceability in line with ISO/IEC 17025 and the GUM uncertainty framework.

Key topics

Scope and intent: Procedures are informative suggestions intended to be sufficient for most practical implementations without restricting expert users.

Maintenance tests: Rationale, decision rules, and general test approaches to verify ongoing conformance of an instrument’s metrological performance.

Applicability of type test: Guidance on when type-test results (Classes A and S) can be applied to maintenance testing.

Clock and timing tests: Verifying timebase performance used in power quality measurements (important for interval timing, flicker and disturbance logging).

Analogue front-end tests: Specific focus on the voltage and current analogue front-ends (magnitude, unbalance, harmonics and other influence factors).

Calibration of artifact reference: Requirements for periodic calibration of reference instruments and artefacts, including treatment of measurement uncertainty and a suggested calibration programme.

Uncertainty and traceability: Use of ISO/IEC Guide 98 (GUM) principles to estimate and apply uncertainty for conformity assessments.

Annex A (informative): Practical integrity checks for portable power analyzers and influence-factor studies (e.g., anti-aliasing filter effects, PLL error, duty factor, amplitude flatness) that can affect harmonic and waveform measurements.

Applications

This Technical Specification is practical for:

Utility and industrial power quality teams performing routine verification of installed power quality meters and analyzers.

Calibration and testing laboratories creating maintenance test procedures and calibration schedules that are traceable to ISO/IEC 17025.

Manufacturers and service providers defining post‑deployment maintenance and field verification programmes for power quality instrumentation.

Consultants and integrators validating instrument fitness before harmonic studies, flicker assessments, or compliance audits.
