2007 SACCom/RAC Luncheon and Annual Meeting

The annual joint meeting of the Standards Advisory and Coordination Committee (SACCom) and Representative Advisory Committee (RAC) was held on Monday, July 9 during a luncheon meeting at the Hawaii Convention Center in Honolulu, Hawaii. David Guzman, the SACCom Chair and Fred Heather, the RAC Chair, co-chaired the meeting. David Guzman opened the meeting with a overview of the SACCom including a review of its scope, representative positions, search for Vice-Chair and Secretary of SACCom and plans for 2008. Plans are underway for a web-based tool for the inputting of reports and communication between members. Both SACCom and RAC are inviting and recruiting additional representatives from other organizations involved with EMC standards such as the FCC and FDA, etc., and EMC processes. Opportunities are being sought for bi-directional interactions with EMC Society presentations at liaison organizations.
The remainder of the meeting was a round the table brief by the members of both committees on their respective group’s activities. Some of the highlights were as follows.
American Institute of Aeronautics and Astronautics (AIAA) Committee on Standards (CoS) S-121-200X, Electromagnetic Compatibility Requirements for Space Equipment and Systems is sponsored by the United States Air Force (USAF) Space and Missile Center (SMC). The committee began with Aerospace Corporation report # TOR 2005 (8387)-1, Electromagnetic Compatibility Requirements for Space Equipment and Systems. After much debate and work, the committee voted to abandon the TOR and began anew based upon MIL-STD-461 E and MIL-STD-464 requirements. This effort has been mistakenly referred to as a “1541 B” by some, but it is not a military standard, has no relationship to the MIL-STD process, and is nothing like MIL-STD-1541 A (retired). AIAA is facilitating the effort for SMC, and will publish the final document.

The annual SACCom meeting held during EMC 2007 drew the experts in the industry, including (from left) Werner Schaefer of Cisco Systems, Steve Berger of TEM Consulting, Andy Drozd of Andro Computational Solutions, Don Heirman of Don HEIRMAN Consultants, Elya Joffe of KTM Project Engineering, and Henry Benitez of ElectroMagnetic Investigations.

The meeting room was full at the annual SACCom/RAC meeting and luncheon held during the 2007 IEEE International Symposium on EMC.

CISPR Subcommittee A, Subcommittee I and ANSI ASC C63™ activities were reported by Don Heirman. CISPR Subcommittee A activities include: testing in Full Anechoic Room-FAR, alternate test methods/sites, effect of turntable material, antenna calibration, site validation/measurements > 1 GHz, uncertainty due to test setup + > 1 GHz and use of spectrum analyzers. The CISPR/TC 77 JTF Projects reported on reverberation testing (61000-4-21), TEM testing (61000-4-20), FAR testing (Pub 16-1-4 and 61000-4-22), and uniform test arrangements for emissions already published in Pub 16-2-3. He also covered CISPR I Multimedia Standards with CISPR 32 Emissions, which ultimately replaces CISPR 13, CISPR 22 in 2008 at the earliest, CISPR 35 Immunity that ultimately replaces CISPR 20 and CISPR 24 due in 2009 at the earliest. The ANSI ASC C63™ activity reported was test site acceptability above 1 GHz, immunity of office equipment, wireless device testing, additional help in ESD testing, in-situ medical device immunity testing, measurement uncertainty and EMC of hearing aids with mobile phones.
ICES Organization (SCC39) was reported by representative Dave Baron. Current activities include drafting a recommended practice for low frequency measurement techniques, 0 – 100 kHz (IEEE C95.3.1), IEEE C95.3–2002 (RF Measurement and Computation) up for review, IEEE C95.6-2002 (Safety Levels 0 – 3 kHz) up for review. IEEE C95.4-2002 (Safe Distance from Antennas During Blasting Operations) up for review, and IEEE 1406 (Guide for Measurement of Quasi-static Electric and Magnetic Fields) up for review [likely will be combined with IEEE C95.3.1]. Their next meeting will be November 28 – 30, 2007 in Irving, Texas at the Nokia Facility.
United States Technical Advisory Group ISO TC22/SC3/WG3 (Automotive EMC – Immunity) was reported on by Chair Kin P. Moy. Current activities involve the development of new test methods for components: ISO 11452-11: “Radiated Immunity – Mode Tuned Reverberation Chamber”, ISO 11452 –12: “Radiated Immunity – Tubular Wave Guide” and coordinating activities with two new working groups: WG 13 (Environmental Conditions) and WG 14 (42 Volts Systems). They held their next meeting in Sydney, Australia in September in conjunction with the CISPR meetings there.
IEC 61326 EMC Product Family Standard for Measurement, Control and Laboratory Equipment was reported on by TC66/SC65A Liaison, Henry Benitez. IEC 61326 has changed from a single standard to several parts. The general immunity requirements are updated to parallel those in the generic immunity standard. The radiated immunity requirements added between 1.4 and 2.7 GHz due to expanding data services above 1 GHz (Wi-Fi, PCS/GSM mobile phones). The new structure for IEC 61326 has Part 1 General Requirements, Part 2 Product Specific Requirements and Part 3 Immunity requirements for equipment performing or intended to perform safety related functions (functional safety) in industrial applications.
Both the SACCom and RAC will be collecting status reports from the representatives and liaisons for the EMC Society Board of Directors meetings. These reports will be shared in the EMC Newsletter after their respective meetings. EMC
