EMC Technologies introduces NATA accredited testing

NATA accredited testing is now available from EMC Technologies.

Testing is available to Power Quality standards EN/IEC 61000-3-2 and EN/IEC 61000-3-3, including the AS/NZS equivalents.

Internationally accepted ISO 17025 NATA accreditation is also available for the calibration of Harmonics and Flicker (H&F) compliance test systems used to measure H&F in per IEC/EN/AS/NZS 61000-3-2 and 61000-3-3.

Accredited calibration of H&F test systems was only previously possible in overseas calibration labs. Shipping of these large and heavy H&F test systems is expensive and risky, which has posed difficulties for Australian test labs wishing to obtain NATA accreditation for testing to H&F standards.

There have also been major inconsistencies in the interpretation of the calibration procedures. Many calibration labs ignored the power source of the H&F test system and it was excluded from the calibration. Two new standards (IEC Technical Reports) have been published to standardise the calibration methods.

These include the 'IEC TR 61000-4-37:2016 Calibration and verification protocol for harmonic emission compliance test systems' and the 'IEC TR 61000-4-38:2015 Test, verification and calibration protocol for voltage fluctuation and flicker test systems'.

Compliance with Harmonics and Flicker standards is mandatory for CE Marking and for certification of energy-savings products under various energy regulator schemes in Australia and overseas.
