INTERNATIONAL STANDARDS ACTIVITY

This issue contains several international standards activity status summaries of possible interest to C63 members. First, a little historical background on the formation of international EMC standards organizations:

CISPR (Comite International Special des Perturbations Radioelectriques) was formed as the result of an ad hoc conference of international organizations held in Paris in 1933. The first meeting of members appointed by their national committees occurred in 1934. No CISPR meetings were held during World War II and work was restarted in 1946. CISPR’s current subcommittees are: “A” – Radio Interference Measurements and Statistical Methods

“B” – Interference Relating to Industrial, Scientific, and Medical (ISM) Radio-Frequency Apparatus, to Other (Heavy) Industrial Equipment, to Overhead Power Lines, to High-Voltage Equipment, and to Electric Traction “D” – Interference Relating to Motor Vehicles and Internal Combustion Engines

“F” – Interference Relating to Household Appliances, Tools, Lighting Equipment, and Similar Apparatus

“H” – Limits for the Protection of Radio Services

“I” – Electromagnetic Compatibility of Information Technology Equipment (ITE), Multimedia Equipment, and Receivers

ANSI ASC C63 is the US Technical Advisory Group for CISPR.

IEC TC 77, “Electromagnetic Compatibility (EMC)” was established in 1973 and held its first meeting at the general IEC meeting in 1974 in Bucharest. The current committee structure is: SC 77A – Low frequency phenomena SC 77B – High frequency phenomena SC 77C – Immunity to high altitude nuclear electromagnetic pulse (HEMP)

CISPR SC A&I

Don Heirman provided the following summary:

CISPR SC A,Radio Interference Measurements and Statistical Techniques”

Recent events of interest:

CISPR/A/467/INF announces the soon to be released reorganization of CISPR 16 on measurement instrumentation, methods and uncertainty into 14 publications. They will be available for purchase in September

CISPR/A/450/DTR was approved and incorporates the general and basic considerations for determining EMC compliance uncertainty. It will be published in September as a technical report

CISPR/A/468/RVD announces successful vote of a document that introduces the site acceptance criteria between 30 and 1000 MHz for test sites to achieve free space or near free space conditions. This comes into play for rooms that are fully absorber lined or the so-called FAR sites. Final FDIS will be released in September.

CISPR/A/460/DA is the draft agenda for the CISPR Subcommittee A agenda for Korea in September. CISPR A is responsible for Pub 16 and all amendments which is the basic pub for the product committees to use.

CISPR SC I, “Electromagnetic Compatibility of Information Technology Equipment, multimedia equipment and receivers”

Recent events of interest:

The limits for information technology equipment for use above 1 GHz failed the national committee voting continuing the problem of no limits above 1 GHz. Proposals are being suggested that are more stringent than the FCC limits in this frequency range.

CISPR/I/75/A announces that the national committees request that the use of ferrite tubes on I/O cables and mains cables for tabletop information technology equipment be removed. Overwhelming support for the removal is shown and that and other test setup changes is about to be released as a committee draft for vote

CISPR/I/77/CDV introduces the use of measurement uncertainty in performing compliance measurements using CISPR Pub 22

CISPR/A/83/DA is the draft agenda for the meeting of CISPR Subcommittee I in Korea in September. Subcommittee I is responsible for Pub 22.

CISPR SC D

Submitted by Poul Andersen

The automotive EMC Immunity Standards Working Group (ISO TC22/SC3/WG3) met June 2-4 in Munich, Germany. Work in progressing on revising and updating the existing published standards. There are presently four documents addressing vehicle RF immunity (ISO 11451-1 thru 4), six documents addressing component RF immunity (ISO 11452-1 thru 5 and –7), one on ESD (ISO 10605) and one on RF probe calibration.(ISO 10305).

A new document in being developed adopting the MIL STD 461E magnetic immunity test. This new document is slated to be called ISO 11452-8.

In the same week (June 4 – 6), CISPR/D/WG1 and WG2 met. In WG1, the decision was made to initiate an amendment to CISPR 12 to clarify the operation of a hybrid vehicle during the RF emissions test.

WG2, which is responsible for CISPR 25, continues to address revisions to the present published document. Specific changes under discussion are related to current probe emissions measurement set-up and test levels.

More controversial is the insistence of the German delegation to include strip line emissions in the international standard. The presentations have been more hype than technical. The decision was made that technical data is needed and will be the basis for making a decision to include or exclude the test method. The US delegation strongly opposes the test method based on data taken here and also the inconsistencies in the data this far presented from the German delegation.

ISO/TC22/SC3/WG3 and CISPR/D/WG1 and WG2 are scheduled to meet in March 2004 in Troy, Michigan.

UPDATE on IEC TC 77 and ACEC ACTIVITIES

By Dr. William A. Radasky, Ph.D., P.E. Chairman IEC SC 77C and ACEC

As an active member of the IEC 77 Chairman’s Advisory Group (CAG) and as the Chairman of the IEC Advisory Committee on EMC (ACEC), I would like to update those interested in the activities of the EMC committees in the IEC (TC 77, SC 77A, SC 77B, and SC 77C). In addition, there are several ongoing activities involving coordination of EMC activities inside and outside of the IEC that may be of general interest.

With regard to TC 77 and its subcommittees, the current activities involved are mainly those of updating and improving existing standards, most of which deal with EMC immunity.

In SC 77B (EMC – high frequency), the famous 61000-4-2, 3, 4, 5, and 6 standards are being improved to provide more accurate calibration techniques and setups for the test equipment, better repeatability, and to introduce efficiency into the test processes (in order to reduce test time and costs). In addition, in the case of 61000-4-3, efforts are being made to deal with the need to test equipment at frequencies above 1 GHz due to the proliferation of emitters in the higher frequency range.

In SC 77C (EMC – high power transients), the work on the nuclear high-altitude EMP (HEMP) is nearly complete with the completion of the 14th IEC publication dealing with this subject. It should be noted that there is great interest in the high-altitude EMP again due to the work of the Congressionally-mandated EMP Commission that is focusing on the threat of HEMP produced by terrorists to the U.S. infrastructure. Attention is being focused on the work of IEC 77C as it has addressed the impacts of HEMP on civil equipment. In addition, SC 77C has started new work dealing with the protection of civil systems and the infrastructure from “RF Weapons”. Three new publications are under development in this area.

In SC 77A (EMC – low frequency), substantial work has been accomplished both on immunity standards and the emission limits for the power network. Their main focus has been on power dips and harmonics. There continues to be some controversy on the emission limits for harmonics for specific types of equipment. This subject is expected to be discussed at the upcoming SC 77A meeting in South Korea in late September.

With regard to coordination between TC 77 and CISPR, work has continued with regard to Joint Task Forces (JTFs) with two projects successfully completed in the past few months – 61000-4-20 (TEM Cells) and 61000-4-21 (Reverberation Chambers). Both of these standards have been developed to describe new basic test techniques with the intention that both emission and immunity testing could be performed in an efficient and cost-effective manner. CISPR/A and SC 77B were both responsible for initiating these projects, and work is beginning on two new JTFs dealing with fully-anechoic room (FAR) testing and uniform test setups for emission and immunity testing.

Finally ACEC has been active with regard to coordinating the application of basic EMC standards with the IEC product committees. A new procedure is underway that involves the review of draft product standards to ensure that the applicable basic EMC standards from CISPR and TC 77 are considered for application. In addition, ACEC has been involved in sponsoring several IEC EMC workshops with presentations in 2002 in Cuba, Iran, and two in China (Shanghai and Beijing). In 2003 workshops are currently being planned for Brazil and Canada (at the Montreal General Meeting). Efforts are also being made to encourage the ISO to apply IEC basic EMC standards in order to avoid the need for duplicate testing to nearly identical (but different) test standards.

Clearly the IEC EMC community is making efforts to maintain and improve existing standards where necessary and to coordinate better with IEC product committees and other international bodies working on EMC standardization. The IEC is also actively looking for contributions from industry in this work; please contact Bill Radasky at wradasky@aol.com if you are interested in participating.
