FCC HAC Meeting3 Copyright 2008 zScope yDevelopment of definitions and methods of measurement of electromagnetic noise and signal strengths (radiated and conducted), determination of levels of signal strength, levels of unwanted sources, limiting ratio of noise (and/or unwanted sources) to signal and development of methods of control of, and guideline for, influence, coupling and immunity. Note: Where subjects deal with overlap with those of other national committees, appropriate liaison will be established. Overview of ASC C63® (EMC) Don Heirman, Chair ASC C63®

FCC HAC Meeting8 Copyright 2008 Subcommittee 8 (Medical) zMaintains C63.18 (in-situ immunity tests) & C63.19 (Hearing Aid Immunity) zThree Working Groups: yRevision of C63.18 yEffect of patient connection yMaintenance of C63.19 zReceives updates on IEC, FDA, and Association for the Advancement of Medical Instrumentation (AAMI) activity zSubcommittee Chair: Joe Morrissey

FCC HAC Meeting9 Copyright 2008 Subcommittee 8 (Medical) zWorking Group 3 (C63.19): y Standard published in 2001, 2006 and 2007 (increased activity as industry needs accelerated) yVersions included ways to make tests easier and more appropriate to accommodate FCC requirements for cell phones to be compatibility with hearing aids y Multiple recirculation ballots—all meeting procedures for acceptance; y Referenced now in FCC Rules

FCC HAC Meeting10 Copyright 2008 Who uses ASC C63® Standards? zManufacturer internal testing groups zIndependent testing organizations zFederal Communications Commission zIndustry affected by or using standard zMembers of US National Committee of the IEC in Technical Advisory Groups as they input to IEC committees for possible harmonization zOthers

FCC HAC Meeting11 Copyright 2008 Advantages to Regulators zReceives industry participation in EMC standardization to meet their needs zRegulators (e.g. FCC): yCan participate in standards process yGet broad input via ANSI public review process yCan cite standard as a reference without repeating in rules or have to do all the work internally yWhere there are voids, agency can (and does) write bulletins and testing procedures with possible adoption/adaptation by ASC C63® yCan rely on proven reputation of ASC C63®

FCC HAC Meeting12 Copyright 2008 ASC C63® publication process zFollows procedures prescribed by the American National Standards Institute z“Approval of standards requires a letter ballot with approval by at least a majority of the balloting group and at least two-thirds of those voting, excluding abstentions” zC63® secretary sends ANSI description of method by which the Standard can be obtained from IEEE zANSI publishes that description in their monthly Standards Action zC63® committee reviews public comments which have been minimal to non-existent

FCC HAC Meeting13 Copyright 2008 Typical standards timeline zProject initiation via ANSI notification zDepending on research/study needed, usually takes 2-3 years to publish (typical of international EMC standards) zIf only simple modifications/improvements needed to existing standard, can be less than a year but more likely a year to 18 months zNext amendment work can start immediately or in parallel with modification underway
