Specification for radio disturbance and immunity measuring apparatus and methods - Part 4-2: Uncertainties, statistics and limit modelling - Measurement instrumentation uncertainty
This part of CISPR 16-4 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. NOTE In accordance with IEC Guide 107, CISPR 16-4-2 is a basic EMC standard for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of the EMC standard. CISPR and its sub-committees are prepared to co-operate with technical committees and product committees in the evaluation of the applicability of this standard for specific products. The annexes contain the background material used in providing the amount of MIU found in generating the CISPR values shown in Clauses 4 through 8 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. The annexes, however, are not intended to be a tutorial or user manual or to be copied when making uncertainty calculations. For that purpose, the references shown in the bibliography, or other widely
recognized documents, may be used. Measurement instrumentation specifications are given in the CISPR 16-1 series, while the methods of measurement are covered in the CISPR 16-2 series. Further information and background on CISPR and radio disturbances is given in CISPR 16-3. The other parts of the
CISPR 16-4 series contain further information on uncertainties in general, statistics and limit modelling. See the introduction of this part for more information on the background and on the content of the CISPR 16-4 series.

Ta del CISPR 16-4 določa metodo za uporabo negotovosti merilnih instrumentov (MIU) pri določanju skladnosti z mejami motenj po CISPR. Gradivo je pomembno tudi za vse preskuse EMC, pri katerih na razlago rezultatov in zaključke vpliva negotovost merilnih instrumentov, uporabljenih med preskušanjem.
OPOMBA: V skladu z Vodilom IEC 107 je CISPR 16-4-2 osnovni standard EMC, ki ga uporabljajo odbori za proizvode IEC. Kot je navedeno v Vodilu 107, so odbori za proizvode odgovorni za določevanje uporabe tega standarda EMC. CISPR in njegovi pododbori so pripravljeni sodelovati s tehničnimi odbori in odbori za proizvode pri ocenjevanju uporabnosti tega standarda za določene proizvode. Dodatki vsebujejo temeljno gradivo, ki se uporablja pri podajanju velikosti MIU, ugotovljene pri nastajanju vrednosti CISPR, prikazanih v točkah od 4 do 8, in so zato koristno temeljno gradivo za tiste, ki potrebujejo začetne in nadaljnje informacije o MIU in informacije o tem, kako v verigi meritev upoštevati posamezne negotovosti. Dodatki niso mišljeni kot priročniki za vajo ali uporabo ali za kopiranje pri izračunavanju negotovosti. V ta namen se lahko uporabljajo reference, navedene v bibliografiji, ali drugi splošno priznani dokumenti.
Specifikacije merilnih instrumentov so podane v seriji CISPR 16-1, merilne metode pa zajema serija CISPR 16-2. Nadaljnje informacije in ozadje o CISPR in radijskih motnjah so navedeni v CISPR 16-3. Drugi deli serije CISPR 16-4 vsebujejo več informacij o negotovosti na splošno, statistiki in modeliranju mejnih vrednosti.

Overview
EN 55016-4-2:2011/A1:2014 (CISPR 16-4-2:2011/A1:2014) is a CLC/CENELEC amendment that specifies how to quantify measurement instrumentation uncertainty for radio disturbance and immunity measuring apparatus and methods. It is part of the CISPR 16 series addressing uncertainties, statistics and limit modelling for electromagnetic compatibility (EMC) measurements. Amendment A1 (2014) adds method-specific guidance - notably for conducted disturbance measurements using a coupling/decoupling network for emission (CDNE) - and expands uncertainty budgets and rationale for input quantities.
Key topics and technical requirements
- Scope: Measurement instrumentation uncertainty for radio disturbance and immunity apparatus (aligned with CISPR 16-4-2).
- New abbreviation: CDNE - coupling decoupling network for emission measurement.
- Measurand (CDNE, 30–300 MHz): asymmetric (common‑mode) disturbance voltage referred to reference ground, expressed in dB(µV).
- Input quantities to consider (examples listed explicitly):
- Receiver reading and related receiver corrections (sine‑wave voltage accuracy, pulse amplitude and repetition response, noise-floor proximity)
- Cable attenuation between CDNE and receiver
- CDNE Voltage Division Factor (VDF) and VDF frequency interpolation error
- CDNE impedance and mismatch effects (CDNE‑receiver)
- Effects of ambient disturbances, grounding, and environment
- Uncertainty budget: Amendment provides a worked uncertainty budget (Table B.7) for conducted measurements with assigned distributions and standard uncertainties; example result: expanded uncertainty U(V) = 2 u(V) = 3.79 dB for the given case.
- Rationale and modelling: Detailed explanations (B.8) justify assumed distributions (normal, triangular, rectangular, U-shaped) and numerical estimates based on calibration reports and component tolerances.
Practical applications
- Ensures repeatable, traceable EMC test results for compliance with regulatory and product standards.
- Used by:
- EMC test laboratories and accreditation bodies preparing uncertainty budgets
- Compliance engineers and product manufacturers performing conducted emissions testing (30–300 MHz)
- Test-equipment and CDNE manufacturers documenting calibration and VDF uncertainty
- Standards committees and auditors assessing measurement quality and reporting consistency
Benefits and SEO keywords
This amendment helps laboratories produce robust measurement uncertainty estimates for conducted disturbance testing using CDNE, improving comparability of EMC test reports and compliance decisions. Keywords: EN 55016-4-2, CISPR 16-4-2, measurement instrumentation uncertainty, EMC measurement uncertainty, CDNE, conducted emissions, uncertainty budget, calibration, receiver corrections.
