Dr. Showers and Mr. Wall Recognized for C63 Service At October Meeting

Project 1-15.7 C63.4 Fully Absorber Lined Room (FAR):

Dennis Camell indicated that the working group was tasked to develop a “white paper” to determine what should be done in C63 on this project that is different from what is being done in CISPR with their joint task force on FAR facilities. There was a draft test plan presented which requires a test “artifact.” This is a floor standing frame with emissions emanating near the base and above to assess any correlation between FARs and OATS or semi-anechoic chambers. The working group plans to use this experiment to determine if there are any technical implementation issues in using these rooms, which includes absorber on all six sides of the chamber and on the top of the turntable. Ken Hall, Michael Foegelle, and Bill Scrivner have FAR chambers that can be used for the A-B comparisons. The Chair noted that this is a joint project with TC-77 for the radiated immunity side of the issue.

Project 1-15.8 Reverberation Chamber Measurement Techniques: Working Group Chair Galen Koepke feels the recently published IEC standard 61000-4-21 is adequate for addressing reverberation chamber test methodology in the USA. SC1 approved suspending this project and recommending to the parent committee that ANSI adopt IEC standard 61000-4-21 with a US Foreword as a C63 standard. The Chair agreed to recommend to the parent committee that C63.022 be retired.

Project 1-15.9 Maintenance of Revision to C63.4-2003: The Chair noted that the C63.4-2003 ballot passed. The ANSI public review process closed in early August without comment. The documentation on voting and resolution is now being reviewed by the ANSI BSR. A new PINS has been submitted to the parent committee that addresses future amendments to this document. GTEMs will be addressed in that revision. Bob Hofmann, Werner Schaefer, Chrys Chrysanthou, Michael Foegelle, Greg Korytkowski, Bill Scrivner, and Mike Windler volunteered to assist Mr. Berger in this effort. This revision is at least two years away as there will be a settling time for using the present version.

Working Group #2 – Howard Bassen – C63.21

Jon Casamento from the FDA gave a brief update on C63.21. This working group is being reorganized. The work effort will take a new direction; the working group will use actual equipment input impedances instead of 50 ohms which was used in the original study.

Working Group #3 – Steve Berger – C63.19

Steve Berger reported on C63.19 – “Methods of Measurement of Compatibility between Wireless Communications Devices and Hearing Aids”. This standard was referenced in a recent FCC Report & Order. Representatives from ATIS, FCC, FDA, the Hearing Aid Industry, cell phone manufacturers and C63 representatives have agreed on a proposed revision to the standard. The revisions are:

Section 4 – RF Emissions – Recommend a validation procedure of the test setup; Change from requirement to test in shielded room to function requirement that environmental ambient be –20 dB to reading; Improved guidance on checking for reflections from test stand and other structures

Section 5 – HA Immunity – Simplify and make more easily automated the movement of the HA; Move annex I (GTEM test alternative) to new section 5.4; GTEM remains a secondary, alternative test; Add an informative annex giving technical justification for the GTEM as an alternative to the dipole illumination test in this application; Make movement the same for dipole and GTEM test methods.

Section 6 – T-Coil Test – Add a new alternative test, section 6.4, for use of broadband signal for T-Coil tests; Recommend mapping of T-Coil signals be performed; Change T-Coil test positions from 5 wireline positions to 3 orthogonal test positions.

Section 7 – Parameters & Categories – Eliminate the requirement to test in analog mode; Add iDEN AWF factor to section 7.1 and information on iDEN to informative annex; Remove note making 7.1 and 7.2 options; Clarify use of AWF with T-Coil tests.

Annexes – Changes in annexes are made supporting changes in body of the document.

A Motion to recommend to the main committee to approve a ballot on the above revisions was unanimously approved.

Unfinished Business:

FDA Report – Jeff Silberberg reported on IEC SC62A Maintenance Team 23 on the International Medical Device EMC standard, IEC 60601-1-2.

*IEC 62A/434/CDV (Amendment 1 to IEC 60601-1-2:2001) out for vote. Voting closes 16 January 2004.

*MT23 met 20-23 May 2003 in Best, Netherlands. Worked on essential performance (immunity compliance criteria): definition and how to identify it (draft informative Annex GGG).

*Essential performance is defined in the draft third edition of IEC 60601-1. The first CDV of this standard was voted down.

*To avoid having a collateral standard define essential performance and to permit better synchronization with the third edition of 60601-1, SC62A Secretary recommended waiting, releasing Annex GGG as Amendment 2 after CDV2 of 60601-1.

*MT23 met 22-24 September 2003 in Frankfurt, Germany. Discussed essential performance in MT and with SC62A Chariman Advisory Group. Decided to replace “essential performance” with defined term “function.” *SC62A presented a seminar on the draft third edition of 60601-1 in Frankfurt on 25-26 September 2003. It is a standard for safety and essential performance of medical electrical equipment and systems, and is based on risk management.

*SC62A met in Frankfurt on 29 September 2003. Discussed, among other topics, that collateral standards should be normative in the third edition of 60601-1. *SC62A Chairman Advisory Group met in Frankfurt on 30 September 2003. Decided that Chairman would recommend that MT23 leave A1 as is, using but not defining “essential performance”. *MT23 members will be submitting comments on 62A/434/CDV, recommending that “essential performance” be replaced with defined term “function.” Also, collateral standards would be normative in the third edition, but only collaterals harmonized with the third edition.

AAMI/EMC Committee Report: Jeff Silberberg reported that the AAMI EMC Committee met 18 June 2003 in Long Beach, California and decided to revise AAMI TIR 18. A task group was set up to develop a proposal for the revision for presentation to the Committee.

FDA Report: Jon Casamento from the FDA reported the following: *FAA/metal detector project(s) is ongoing *Added EMC statement to FDA rule for bar coding of drugs and biologics *Don Witters participating in IEEE Study Group on evaluation of wireless performance *JCAHO - Working on a draft article on EMC/EMI in hospitals. *Preparing comments on ISO TC215 draft technical report, The Use of Mobile Wireless Equipment in the Hospital for Communication and Health Informatics: Recommendations for the Management of EMI with Life Critical Medical Devices *Seminar 15 September on EMI in Hospitals –Radio Advisory Board Canada (advisory group to Industry Canada). Decided to support Medical Devices Bureau in holding a second Canadian/US Roundtable, in 2004.

Mobile Healthcare Alliance (MoHCA) Report: A task group is working on recommendations for EMC/EMI in healthcare facilities.

CISPR SC A: Radio Interference Measurements and Statistical Techniques Representative:Don Heirman

Recent events of interest: CISPR SC A held its annual meeting in Jeju Korea on 22 September 2003. There were 75 participants from 20 countries. Major decisions and actions were:

1. Activity continues to be high for site validation, measurement methods and measurement instrumentation for emission testing above 1 GHz: *New procedure for site validation using a VSWR technique using an omnidirectional transmit antenna has moved to the committee draft for vote (CDV) stage *New measurement method for performing radiated emission measurements using a planar receive antenna scan with details on height scan increments and antenna performance requirements. *Effect of turntable, table tops and antenna towers on EUT emissions moved to a second committee draft (CD) stage to include the effect of the test setup as well as the support structures *A technique using amplitude probability distribution for mea ruing discontinuous emissions moved to a second CD stage to include background information so that users will have this to introduce the APD technique *The possible addition of a weighting function for the detector when measuring interference according to its effect on digital communication services
2. Decision was made to accept the E-field approach for emission measurements which includes as reference antennas, the commonly used biconical and log periodic antennas for their respective ranges in the 30-1000 MHz range.
3. The publication date for the 14 parts of CISPR 16 was moved back to the end of October to include more of the French translations. This is important as CENELEC has indicated that they want to harmonize all CISPR 16 publications and hence enter into the parallel voting procedures with CISPR.

CISPR B: Interference Relating to Industrial, Scientific, and Medical Radio Frequency Apparatus Representative:Daniel D. Hoolihan

Current Activities: There was a Working Group 1 meeting of CISPR B in Zurich on February 17 and 18. Highlights of his trip report are as follows: *The WG is performing maintenance cycle work on CISPR

11. Arc welders will remain in Group 2 for the present time. Resistance welders will be in Group 1. *Micro-wave UV irradiator standard is to be published as an FDIS. Danish and Swedish comments and objections were disapproved. *Comments for Digital Radio Detector were distributed to CISPR/A. CISPR/A comments:

Distribute a second CDV Do a round-robin test to validate new detector

*CISPR/B will not adopt the ITU definition of ISM equipment. The ITU definition is for the use of the equipment. The CISPR definition is for the products. *Measurement uncertainty and the application within CISPR 11 was referred to WG1 to be added to the Maintenance Cycle changes. *The WG is performing maintenance cycle work on CISPR

11. Arc welders will remain in Group 2 for the present time. Resistance welders will be in Group 1. *Micro-wave UV irradiator standard is to be published as an FDIS. Danish and Swedish comments and objections were disapproved. *Comments for Digital Radio Detector were distributed to CISPR/A. CISPR/A comments:

Distribute a second CDV

Do a round-robin test to validate new detector *CISPR/B will not adopt the ITU definition of ISM equipment. The ITU definition is for the use of the equipment. The CISPR definition is for the products. Measurement uncertainty and the application within CISPR 11 was referred to WG1 to be added to the Maintenance Cycle changes. *CISPR/A has decided to leave the text that Linear Average detector is preferred but due to use of log average detector in CISPR/B, the use of log average detector will be allowed. *CISPR/B is asking for better technical justification for the statement about use of Class A equipment in Class B environments. *CISPR/B Maintenance Cycle will be delayed by 1 year due to large volume of comments in regard to new classification and new power based conducted emissions limits. New proposed publication date is 3/2005. *CISPR 18 has been set to Stage 0 for all 3 parts due to lack of technical input. *CISPR 26 is being withdrawn from the CISPR/B program of work *CISPR 210 is being referred to ITU since it is an ITU issue, not a CISPR issue. *The decision to require further justification for the installation and use of Class A equipment in Class B environments is a significant issue for the manufacturers of medical devices. The failure is due to accurate assessment of the difference between residential, commercial, and industrial environments. Guide 107 lists all 3 environments. CISPR only recognizes 2 environments by placing commercial and light industrial environments in the residential category. *Further work and justification for power related relaxation for conducted emissions for high power systems is required.

CISPR H Title:Limits for the protection of radio services Representative:Werner Schaefer

Current Activities: The subcommittee met on September 24 and 25, 2003, in Jeju/Korea. The following issues and documents were discussed:

1. Committee Draft on 61000-6-3 and 61000-6-4 *The two separate generic emission standards will not be merged into a single document; *The definition of environments shall be coordinated with

the TC77 work on the generic immunity standards.

*Two new CDs are to be issued

*As far as the emissions requirements below 9 kHz is concerned, the chairman of CISPR/H will contact SC77A for the appropriate requirements and accompanying text to be included eventually in the generic emission standards. This text will also be included in the next CDs.

*The proposal to have both Class A and Class B limits in 61000-6-3 was not accepted. *The proposal to have both Class A and Class B limits in 61000-6-4 was not accepted. *The proposal to allow alternative measurements in Fully Anechoic Rooms was accepted. *The proposal to allow in-situ measurements was accepted.

1. Document for Comments on limits above 1 GHz: To address numerous concerns in regard to cooperation between CISPR/I and CISPR/H on the subject, the Chairman proposed to take the decisions of CISPR/I into consideration, as follows:
2. *If CISPR/I issues a CD after its Jeju Meeting, CISPR/H will temporarily put its work on limits above 1 GHz in the generic standards on hold and concentrate solely on the rationale for limits until the CISPR/I decisions and conclusions are known. *If CISPR/I does not issue a CD immediately CISPR/H will offer collaboration in order to organize a joint meeting. *The subcommittee accepted this proposal.
1. Rationale for the setting of emission limits:

*The document for comments (CIS/H/62A/DC) on the influence factors was reviewed in detail and the following decisions were made

*CISPR 23: it was agreed that the intention is to update CISPR 23 to include this new material. Some relevant parts from CISPR 16-3 are proposed to be transferred to CISPR 23.

*3558 Frequency range: The rationale should cover the whole frequency range up to 18 GHz.

*It was agreed ti issue a CD to replace CISPR 23 in total. The CD may be supplemented with one or more DC(s) to solicit further input on specific subjects.

1. Archive for justifications for product limits that exceed the generic limits: The comments on CIS/H/59/DC were reviewed and most comments were accepted. The Ch airman will present a revised proposal to CISPR/S for approval before submission to other Committees. Received comments form other subcommittees will be collected and presented by CISPR/H.
2. Database on the characteristics of radio services 936: The Chairman introduced the work and the positive voting result, as documented in CIS/H/66/RVCMr. Baillif from the IEC Central Office indicated that CISPR 31, Edition 1 will be published on 10 October 2003. The Convener explained the

ongoing work to implement the database in the IEC web site. It is the intention to have it implemented by the end of 2003. It will be announced to encourage data on radio services throughout the world to be submitted.

Recently Published Standards: CISPR 31 will be published in October 2003

Scheduled Future Projects: *CISPR 32 will be changed to CISPR 23. Next CD due June 2004 *CISPR 33 will be deleted *CISPR 34 will be put to stage 0 *IEC 61000-6-3 as planned *IEC 61000-6-4 as planned

CISPR SC I :Electromagnetic Compatibility of Information Technology Equipment, multimedia equipment and receivers Representative: Don Heirman

Recent events of interest:

1. The annual CISPR I meeting was held in Jeju Korea on 1 October 2003. Items of interest included: 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 were suggested as a compromise and two new CDVs will be issued by the end of the year to cover 1-6 GHz and 6 to 18 GHz. The limits will be 50 dBuV/m (average) for class B at 3 meters for 1-3 GHz; 54 dBuV/m (average) for class B at 3 meters for 3 to 18 GHz which is the same as the FCC limits in the USA. There will be a 6 dB relaxation for Class A products. The peak to average ratio has to be less than 20 dB. Finally the measurement procedure will be that being produced by CISPR SC A as noted above in the CISPR A report.
2. Improvements to CISPR 22 contained in CISPR/I/71/CDV on telecom measurements passed and will be issued as a final draft international standard (FDIS) as soon as the CISPR/A/431/CDV FDIS passes in Subcommittee A
3. A CD for non-invasive telecom cable testing was approved
4. Work on the method to assess the power line impedance for powerline communications (PLC) systems compliance measurements moves to the CD stage by the first of November.
5. There was a new work item (NP) proposing the consolidation of CISPR 13/22 and 20/24 on emission and immunity measurements into one document met with objections since text was appended to the NP went too far and was not reviewed by the ad hoc team writing the document. A suggestion to withdraw, recast, etc. was made.

1. A CD will be circulated to include the CENELEC common modifications to CISPR 22 into the next edition of CISPR 22. Two modifications were to remove the “2 dB rule” on when to stop maximizing (and presumably continue to maximize for a very long time) and to increase the height of floor standing equipment abover the ground plane to 15 cm instead of the present 12 mm (to make it possible to keep such eqauipment on transporting skids due to not safely being able to remove heavy equipment from the skid).
2. Finally, the work was reorganized and the following WG

assignments were made *WG1: Maintenance of CISPR 13 and 20 (receivers) *WG2: Multimedia emissions (new publication?) *WG3: Maintenance of CISPR 22 and 24 *WG4: Multimedia immunity (new publication?)

National Committees will be asked to re-appoint their experts for each WG.

IEC TC77 & ACECTitle:“Standardization in the field of EMC” Representatives:Prof. Michel Ianoz

Current Activities:

1. SC77B: SC77B held a meeting (as usual each two years) in Jeju (South Korea) on October 1, 2003. The meeting was attended by 30 delegates and 5 observers. The 30 delegates came from the following 13 P members : CA, CN, FI, FR, DE, IT, JP, KR, NL, ZA, CH, UK, USA. The following decisions were taken :

*The project IEC 61000-4-2 Edition 2.0 will be put at stage 0 *The WG9 will be disbanded and a new maintenance team created *The maintenance dates for the next version of each basic standards have been established *The WGs are requested to take over the uncertainty issue in a limited time (no more than two years).

The rationale for putting the project IEC 61000-4-2 Edition

2.0 at stage zero is that the time limit of 6 years imposed by the Central Office of IEC for a new document can not be respected.

The proposed changed will be discussed in the maintenance teem for this standard.

Concerning Annex C of 61000-4-12, which was prepared by a JTF 77B/77C, a certain number of comments have been received. These comments are positive about the document, they ask for a few technical or editorial improvements. An answer to these comments will be prepared and the next step of the amended 61000-4-12 will be a CDV, after the WG11 meeting on December 8, in Erlangen, Germany.

SC77C: SC77C held a meeting (as usual each two years) in Jeju (South Korea) on September 29, 2003. The Swedish Secretariat will stop at the end of 2004. The Secretariat will probably be taken over by the UK NC.

Work in progress pertains to three standards:

*61000-1-5, High power EM (HPEM) effects on civil systems.

*61000-2-13, HPE environments – radiated and conducted. *61000-4-33, Measurement methods for high power transient parameters.

Recently Published Standards:

*61000-1-3, The effects of HEMP on civil equipment and systems (Technical Report).

*61000-4-25, HEMP immunity test methods for equipment and systems.

*61000-4-32, HEMP simulator compendium (Technical Report).

*61000-5-6, Mitigation of external EM influences (Technical Report).

*61000-6-6, HEMP immunity for indoor equipment.
