CISPR 11:2015 is available as CISPR 11:2015 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
CISPR 11:2015 applies to industrial, scientific and medical electrical equipment operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances designed to generate and/or use locally radio-frequency energy. This standard covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. Measurements need only be performed in frequency ranges where limits are specified in Clause 6. For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (see Definition 3.13), this standard covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz. Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this standard. Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this standard. This sixth edition cancels and replaces the fifth edition published in 2009 and its Amendment 1 published in 2010. It constitutes a technical revision. It introduces and permits type testing on components of power electronic equipment, systems and installations. Its emission limits apply now to low voltage (LV) a.c. and d.c. power ports, irrespective of the direction of power transmission. Several limits were adapted to the practical test conditions found at test sites. They are also applicable now to power electronic ISM RF equipment used for wireless power transfer (WPT), for instant power supply and charging purposes. The limits in the range 1 GHz to 18 GHz apply now to CW-type disturbances and to fluctuating disturbances in a similar, uniform and technology-neutral way. For these measurements, two alternative methods of measurement are available, the traditional log-AV method and the new APD method. It has the status of a Product Family EMC standard in accordance with IEC Guide 107, Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications (2014).

Overview
EN 55011:2016 (CISPR 11:2015, modified) is the European adoption of the international EMC product-family standard for industrial, scientific and medical (ISM) equipment. It defines radio‑frequency disturbance characteristics, limits and methods of measurement for equipment that generates or uses RF energy. The standard covers equipment ranges up to 400 GHz, with emission requirements specified for 9 kHz to 400 GHz and ISM RF applications specifically covered to 18 GHz where noted.
Key topics and technical requirements
- Scope and classification: Applies to ISM equipment and domestic/similar appliances designed to generate or use RF energy; equipment already covered by other CISPR product standards is excluded.
- Emission limits: Limits are defined for both conducted emissions (power ports) and radiated emissions (test sites). Measurements are required only in frequency ranges where limits are specified (Clause 6).
- Power ports: Emission limits now apply to low-voltage (LV) a.c. and d.c. power ports irrespective of power direction (inbound/outbound).
- Measurement methods: Radiated limits from 1 GHz to 18 GHz apply uniformly to CW and fluctuating disturbances. Two alternative measurement methods are available - the traditional log‑AV method and the newer APD method.
- Component testing & power electronics: Sixth edition permits type testing on components of power electronic equipment and extends applicability to power‑electronic ISM RF equipment used for wireless power transfer (WPT), instant power supply and charging.
- Test apparatus and references: Measurement apparatus and test-site requirements refer to CISPR/IEC measurement documents (CISPR 16 series) and other related IEC standards cited in the normative annexes.
Applications and who uses it
EN 55011 is essential for:
- EMC engineers and test laboratories performing radiated and conducted emission testing
- Manufacturers of ISM equipment (microwave heating, induction heaters, UV irradiators, welding and medical RF devices) seeking compliance and CE marking

Resolution No. 63 of the ITU Radio Regulations applies.
b
The term “unrestricted” applies to the fundamental and all other frequency components falling within the designated
band. Outside of ITU designated ISM bands the limits for the disturbance voltage and radiation disturbance in this
standard apply.
In some CENELEC countries, different or additional frequencies may be designated for use with
ISM RF applications in the meaning of the definition found in the ITU Radio Regulations, see
definition 3.13. These frequencies are listed in Table ZB.1 (see Annex ZB).
The limits for the disturbance voltage and radiation disturbance defined in this standard do also not
apply to the fundamental ISM frequencies listed in Table ZB.1. If ISM RF applications use fundamental
frequencies other than the ITU or nationally designated frequencies, then the limits for the disturbance
voltage and radiation disturbance of this standard apply also to these fundamental frequencies.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
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.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (includi

The article discusses the standard EN 55011:2016, which is related to the radio-frequency disturbance characteristics of industrial, scientific, and medical equipment. The standard applies to equipment operating in the frequency range of 0 Hz to 400 GHz and covers emission requirements for radio-frequency disturbances in the frequency range of 9 kHz to 400 GHz. It also includes requirements for ISM RF lighting equipment and UV irradiators operating within the ISM frequency bands defined by the ITU Radio Regulations. The sixth edition of the standard introduces type testing on components of power electronic equipment and applies emission limits to low voltage a.c. and d.c. power ports. The limits also now include power electronic ISM RF equipment used for wireless power transfer. Additionally, the standard provides two alternative methods of measurement, the log-AV method and the APD method. It is considered a Product Family EMC standard in accordance with IEC Guide 107.
記事タイトル：EN 55011：2016-産業科学医療機器-無線周波数障害特性-制限および測定方法 記事の内容：CISPR 11：2015は、国際標準とその前のバージョンの技術内容の変更をすべて表示するレッドラインバージョンを含んでいます。CISPR 11：2015は、0 Hzから400 GHzの周波数範囲で動作する産業、科学、医療用電気機器およびラジオ周波数（RF）エネルギーを生成および/または使用する家庭用および同様の電気機器に適用されます。この基準は、9 kHzから400 GHzの周波数範囲のRF障害に関連する放射要件をカバーしています。測定は、6節で指定された制限がある周波数範囲でのみ実施する必要があります。 ITU無線規則（ITU Radio Regulations）で定義されているISM RFアプリケーションの意味で、この基準は、9 kHzから18 GHzの周波数範囲のRF障害に関連する放射要件をカバーしています。 ITU無線規則で定義されているISM周波数帯域で使用されるISM RF照明機器およびUV照射装置の要件がこの基準に含まれています。他のCISPR製品および製品ファミリーの放射性規格に該当する機器は、この基準の対象外です。この6th版は、2009年に発行された5th版と、2010年に公開された修正1版を取り消し、置き換え、技術的改定を行っています。この標準では、電力電子機器、システム、および設置の部品に対する型式試験を導入し、許可しています。放射制限は、従来の低電圧（LV）交流および直流電源ポートに向けて、電力伝送の方向に関係なく、適用されるようになりました。一部の制限は、試験場の実際的な試験条件に合わせて適応されました。また、ワイヤレス電力転送（WPT）、インスタント電源供給、および充電目的に使用される電力電子ISM RF機器にも適用されます。1 GHzから18 GHzの範囲の制限は、CWタイプの障害および変動する障害にも同様の一貫したテクノロジーニュートラルな方法で適用されます。これらの測定には、従来のログ-AV方法と新しいAPD方法の2つの代替測定方法が利用可能です。それは、2014年のIECガイド107、「電磁両立性-電磁両立性発行の起草ガイド」に従って、商品ファミリーEMCの標準であるとの地位を持っています。
기사 제목 : EN 55011:2016 - 산업, 과학 및 의학 장비 - 무선 주파수 잡음 특성 - 한도 및 측정 방법 기사 내용: CISPR 11:2015는 국제 표준과 그 이전 판에 대한 기술 내용의 변경 사항을 모두 보여주는 레드라인 버전을 포함한 <a href="https://webstore.iec.ch/publication/22635"> CISPR 11:2015 RLV</a>로 사용 가능합니다. CISPR 11:2015는 0 Hz에서 400 GHz의 주파수 범위에서 작동하는 산업, 과학 및 의학 전기 장비 및 라디오 주파수 에너지를 생성하고/또는 사용하는 가정용 및 비슷한 가전제품에 적용됩니다. 이 표준은 9 kHz에서 400 GHz의 주파수 범위에서의 무선 주파수( RF) 잡음과 관련된 방출 요구 사항을 다룹니다. 측정은 6 절에서 한도가 지정된 주파수 범위에서만 수행해야 합니다. ITU 무선규정(ITU Radio Regulations)의 정의에서 찾을 수 있는 의미의 ISM RF 응용 분야에 대해서는, 이 표준은 9 kHz에서 18 GHz의 주파수 범위에서의 무선 주파수 장애와 관련된 방출 요구 사항을 다룹니다. ITU 무선규정에서 정의한 ISM 주파수대역 내에서 사용된 ISM RF 조명장비 및 UV 조사 장치에 대한 요구 사항이 이 표준에 포함되어 있습니다. 이 표준의 범위를 벗어나는 다른 CISPR 제품 및 제품 군 방출 표준에 해당하는 장비는 이 표준의 범위에서 제외됩니다. 이 6판은 2009년 발행된 5판과 2010년 공개된 1차 수정판을 취소하고 대체하는 기술적인 개정판입니다. 이 표준은 전자파 호환성 기술 시스템 및 설비에서 구성 요소에 대한 유형 시험을 도입하고 허용합니다. 이 전도 표준의 방출 한계는 이제 전력 전송 방향과 상관없이 저전압 (LV) 교류 및 직류 전력 포트에 적용됩니다. 일부 한도는 시험장의 실제 시험 조건에 맞춰 조정되었습니다. 또한 이제 1 GHz에서 18 GHz의 범위에서는 CW 형태의 장애와 불규칙한 장애에 대해서도 유사하고 일관되며 기술 중립적인 방식으로 적용됩니다. 이 측정을 위해 전통적인 로그-AV 방법과 새로운 APD 방법 두 가지 대안적인 측정 방법이 제공됩니다. 이 표준은 2014년에 제정된 IEC 가이드 107, 전자파 호환성- 전자파 호환성 발표작성 가이드에 따라 제품군 EMC 표준으로서의 지위를 가지고 있습니다.
