EMC and Measurement Uncertainty – LAB 34 and CISPR 16-4-2

Two of the more important publications in the area of Electromagnetic Compatibility (EMC) and Measurement Uncertainty (MU) are LAB 34 and CISPR 16-4-2. EMC and Measurement Uncertainty are receiving more attention as other CISPR Product Family Standards begin to adopt MU. LAB 34 is “The Expression of Uncertainty in EMC Testing” and is published by the United Kingdom Accreditation Service (UKAS). CISPR 16-4-2 is published by the International Electrotechnical Commission (IEC) and is titled “Specification for Radio Disturbance and Immunity Measuring Apparatus and Methods – Part 4-2: Uncertainties, Statistics, and Limit Modeling – Uncertainty in EMC Measurements.” This article compares and contrasts the two MU documents.
