Specification for radio disturbance and immunity measuring apparatus and methods - Part 4-2: Uncertainties, statistics and limit modelling - Measurement instrumentation uncertainty

CISPR 16-4-2:2011 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. 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. The contents of the corrigendum of April 2013 have been included in this copy.

Spécifications des méthodes et des appareils de mesure des perturbations radioélectriques et de l'immunité aux perturbations radioélectriques - Partie 4-2: Incertitudes, statistiques et modélisation des limites - Incertitudes de mesure de l'instrumentation

La CISPR 16-4-2:2011 est une publication fondamentale en CEM. Elle spécifie la méthode d'application de l'incertitude de mesure de l'instrumentation (MIU) à la détermination de la conformité aux limites de perturbation du CISPR. Cela s'applique également à tous les essais CEM lorsque l'interprétation des résultats et les conclusions peuvent être influencées par l'incertitude de l'instrumentation de mesure utilisée pendant les essais. Cette deuxième édition constitue une révision technique. Elle inclut les modifications techniques majeures concernant les méthodes de mesure des perturbations conduites via les accès secteur et les accès télécommunication, ainsi que concernant les méthodes de mesure des perturbations rayonnées au moyen d'une FAR, dans la gamme de fréquences de 30 MHz à 1 000 MHz et de 1 GHz à 18 GHz. Les annexes contiennent les éléments de référence utilisés pour fournir la quantité de MIU trouvée dans l'élaboration des valeurs CISPR indiquées dans le document principal, et en conséquence, fournissent également des informations importantes pour ceux qui ont besoin à la fois d'informations initiales et complémentaires sur les MIU et sur la façon de prendre en compte les incertitudes individuelles dans la chaîne de mesure. Toutefois, les annexes ne sont pas destinées à être un modèle didactique ou un manuel d'utilisateur ou encore à être reproduites pour effectuer des calculs d'incertitude. A cet effet, il est possible d'utiliser les références fournies dans la bibliographie ou dans d'autres documents de fiabilité reconnue. Les spécifications des instruments de mesure sont données dans la série CISPR 16-1 et les méthodes de mesure sont couvertes par la série CISPR 16-2. Des informations complémentaires et références contextuelles sur les perturbations CISPR et radioélectriques sont données dans la CISPR 16-3. Les autres parties de la série CISPR 16-4 contiennent des informations complémentaires sur l'incertitude en général, les statistiques et la modélisation des limites. Le contenu du corrigendum d'avril 2013 a été pris en considération dans cet exemplaire.

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

INTRODUCTION

The CISPR 16-4 series, Specification for radio disturbance and immunity measuring

apparatus and methods – Uncertainties, statistics and limit modelling, contains information

related to uncertainties, statistics and limit modelling, and consists of the following five parts:

• Part 4-1: Uncertainties in standardized EMC tests,
• Part 4-2: Measurement instrumentation uncertainty,

• Part 4-3: Statistical considerations in the determination of EMC compliance of mass-

produced products,

• Part 4-4: Statistics of complaints and a model for the calculation of limits for the protection

of radio services, and
• Part 4-5: Conditions for the use of alternative test methods.

For practical reasons, standardized electromagnetic compatibility (EMC) tests are simplified

representations of possible electromagnetic interference (EMI) scenarios that a product may

encounter in practice. Consequently, in an EMC standard, the measurand, the limit,

measurement instruments, measurement set-up, measurement procedure and measurement

conditions are simplified but are still meaningful (representative). Here meaningful means that

there is a statistical correlation between compliance of the product with a limit, based on a

standardized EMC test using standardized test equipment, and a high probability of actual

EMC of the same product during its life cycle. Part 4-4 provides methods based on statistics

to derive meaningful disturbance limits to protect radio services.

In general, a standardized EMC test should be developed such that reproducible results are

obtained if different parties perform the same test with the same EUT. However, various

uncertainty sources limit the reproducibility of a standardized EMC.

Part 4-1 is a technical report that consists of a collection of informative reports that address

all relevant uncertainty sources that may be encountered during EMC compliance tests.

Typical examples of uncertainty sources are the EUT itself, the measurement instrumentation,

the set-up of the EUT, the test procedures and the environmental conditions.

Part 4-2 describes a specific category of uncertainties, i.e. measurement instrumentation

uncertainties. In this part, examples of MIU budgets are given for most of the CISPR

measurement methods. Also in this part, normative requirements are given on how to apply

the MIU when determining compliance of an EUT with a disturbance limit (i.e. conformity

assessment decision).

Part 4-3 is a technical report that describes the statistical treatment of test results when

compliance tests are performed on samples of mass-produced products. This treatment is

known as the 80 %/80 % rule.

Part 4-4 is a technical report that contains CISPR recommendations for the collation of

statistical data on interference complaints and for the classification of interference sources.

Also, models for the calculation of limits for various modes of interference coupling are given.

Part 4-5 is a technical report describing a method to enable product committees to develop

limits for alternative test methods, using conversions from established limits.

Measurement instrumentation uncertainty
1 Scope

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.
