New Edition of CISPR 16-4-2 Published

A new edition of CISPR 16-4-2 has been published by the International Electrotechnical Committee. CISPR 16-4-2 applies to “Specification for radio disturbance and immunity measuring apparatus and methods – Part 4-2: Uncertainties, statistics and limit modelling – Measurement instrumentation uncertainty.” The new edition is available for purchase on the IEC’s website.

Description*

CISPR 16-4-2:2011+A1:2014 is a basic EMC publication. It specifies the method of applying Measurement Instrumentation Uncertainty (MIU) when determining compliance with CISPR disturbance limits. The material is also relevant to any EMC test when interpretation of the results and conclusions reached will be impacted by the uncertainty of the measurement instrumentation used during testing. This second edition includes significant technical additions about methods of conducted disturbance measurements on mains and communication ports and about methods of radiated disturbance measurements using a FAR in the ranges of 30 MHz to 1 000 MHz and of 1 GHz to 18 GHz. The annexes contain the background material used in providing the amount of MIU found in generating the CISPR values shown in the main document and hence provide valuable background material for those needing both initial and further information on MIU and how to take individual uncertainties in the measurement chain into account.”
