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.

- 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.

SIST EN 55016-4-2:2011/A1:2014 표준은 전자기 방해와 면역 측정 기구 및 방법에 대한 규격을 제공하며, 특히 측정 기구의 불확실성을 다루는 중요한 부분입니다. 이 표준의 범위는 CISPR 방해 한계 준수를 확인할 때 적용되는 측정 기구 불확실성(MIU)의 적용 방법을 구체적으로 규명하고 있습니다. 또한, 모든 EMC 시험에서 측정 기구의 불확실성이 결과 해석과 결론에 미치는 영향을 고려해야 함을 강조합니다. 이 표준의 강점 중 하나는 CISPR 16-4-2가 IEC 가이드 107에 따라 기본 EMC 표준으로 활용될 수 있다는 점입니다. 제품 위원회는 EMC 표준의 적용 가능성을 결정하는 책임이 있으며, CISPR와 그 하위 위원회는 특정 제품을 위한 이 표준의 적용 가능성 평가에 기술 위원회 및 제품 위원회와 협력할 준비가 되어 있습니다. 이는 사용자와 제조업체가 EMC 현황을 명확히 이해하는 데 기여할 수 있습니다. 또한, 부록에서는 CISPR 값 생성 과정에서 발견된 MIU의 양을 제공하는 배경 자료를 포함하고 있어, MIU에 대한 기초 및 추가 정보를 필요로 하는 이들에게 유용한 리소스를 제공합니다. 그러나 이러한 부록은 교육 자료나 사용자 매뉴얼로 활용될 의도가 아니며, 불확실성 계산을 위한 목적에는 문헌에서 제공되는 참고 문헌이나 기타 널리 인정받는 문서를 사용하는 것이 바람직합니다. 마지막으로, 측정 기구의 규격은 CISPR 16-1 시리즈에서 제공되며, 측정 방법은 CISPR 16-2 시리즈에서 상세히 다루고 있습니다. CISPR 및 무선 방해에 대한 추가 정보는 CISPR 16-3에서 찾을 수 있으며, CISPR 16-4 시리즈의 다른 부분에서는 불확실성, 통계 및 한계 모델링에 대한 더 많은 정보를 제공합니다. 이 표준이 전자기 적합성을 이해하고 보장하는 데 중요한 역할을 한다는 점은 분명합니다.
SIST EN 55016-4-2:2011/A1:2014は、無線妨害および耐性測定装置と方法に関する標準であり、特に測定機器の不確かさ（Measurement Instrumentation Uncertainty: MIU）に焦点を当てています。この標準は、CISPRの妨害限界に対する適合性を評価する際に、MIUの適用方法を明確に指定しています。これは、電磁両立性（EMC）テストにおける結果の解釈と結論に影響を与えるため、非常に重要です。 この標準の強みは、測定機器の不確かさを定量化することにより、テスト結果の信頼性を向上させる点にあります。また、IECガイド107に基づいて、プロダクトコミッティがEMC標準の適用可能性を判断するための基本的な枠組みを提供しています。そのため、業界における様々な製品検討においても広く適用されることが期待されます。 また、付属書には、CISPR値を生成する際のMIUの算出過程に関する背景資料が含まれており、不確かさの計算に関する貴重な情報を提供しています。ただし、付属書はチュートリアルやユーザーマニュアルではないため、不確かさの計算には参考文献を利用することが推奨されています。 SIST EN 55016-4-2:2011/A1:2014は、CISPR 16-1シリーズにおける測定機器の仕様や、CISPR 16-2シリーズによる測定方法とも連携しており、EMCに関する包括的な理解を提供します。これにより、無線妨害の評価や技術的な問題解決に向けた実用的なガイダンスを得ることができます。全体として、この標準はEMC分野における研究および実装の現場での実用性と重要性を兼ね備えています。
The SIST EN 55016-4-2:2011/A1:2014 standard establishes a comprehensive framework for applying Measurement Instrumentation Uncertainty (MIU) in compliance assessments with CISPR disturbance limits. This standard is pivotal within the context of Electromagnetic Compatibility (EMC) testing, as it directly addresses the influence of measurement uncertainties on the interpretation of results, ensuring that evaluations are accurate and reliable. One of the primary strengths of this standard lies in its detailed specification of methodologies for quantifying MIU, which is critical for regulatory compliance across various EMC contexts. By integrating these methodologies, users can better understand and manage the uncertainties associated with measurement instrumentation, leading to enhanced confidence in the compliance verification process. The relevance of this standard extends beyond just compliance; it serves as a fundamental resource for product committees of the IEC, as mentioned in IEC Guide 107. Its guidance on MIU makes it particularly useful for organizations aiming to ensure that their products meet stringent EMC requirements. The standard encourages collaboration among CISPR and its sub-committees with various technical committees, fostering a comprehensive approach to EMC standards application. Furthermore, the annexes of the document offer essential background material that aids in understanding how MIU is derived, though they are not meant to function as manuals for calculating uncertainties. This clarity ensures users can access relevant context and guidance without it becoming overwhelming or prescriptive. Overall, the SIST EN 55016-4-2:2011/A1:2014 standard is a critical document for anyone involved in EMC testing, providing robust methodologies for measurement uncertainty that are directly applicable to achieving compliance with CISPR disturbance limits. Its structured approach to uncertainty management highlights its significance in the field of electromagnetic compatibility, enhancing its relevance in both current and future compliance assessments.
Le document SIST EN 55016-4-2:2011/A1:2014 présente une spécification essentielle pour les appareils et méthodes de mesure de la distorsion radio et de l'immunité, en se concentrant particulièrement sur l'incertitude de l'instrumentation de mesure. Son champ d'application permet de clarifier l'utilisation de l'incertitude d'instrumentation en matière de mesure (MIU) lors de la détermination de la conformité aux limites de perturbation établies par CISPR. Ce cadre est non seulement pertinent pour des mesures de conformité mais aussi pour toute évaluation de tests EMC, où l'interprétation des résultats peut être sensiblement affectée par l'incertitude des outils de mesure employés. Parmi les points forts de cette norme, on trouve la clarté qu'elle apporte sur la manière d'appliquer la MIU, ce qui est crucial pour les comités de produits concernés par les normes EMC. La norme renforce la coopération entre divers comités techniques et de produits pour évaluer l'applicabilité de cette règle à des produits spécifiques. Les annexes incluses fournissent un matériel de référence important quant à l'évaluation de l'incertitude de mesure, même si elles ne sont pas destinées à servir de tutoriels ou de manuels d’utilisation. La structuration de cette norme en relation avec les autres parties de la série CISPR 16 renforce son efficacité; les spécifications d'instrumentation de mesure sont référencées dans la série CISPR 16-1, tandis que les méthodes de mesure sont traitées dans la série CISPR 16-2. Cela garantit que tous les aspects nécessaires à une compréhension complète de l'incertitude de mesure et de son application dans le cadre EMC sont couverts. Ainsi, la norme SIST EN 55016-4-2:2011/A1:2014 constitue un outil précieux pour les professionnels de l’évaluation de la compatibilité électromagnétique, car elle établit des bases solides pour la gestion des incertitudes dans les mesures, contribuant ainsi à une meilleure validité des résultats et à la conformité avec les exigences réglementaires.
