STEPS to STANDARDISATION 1933 CISPR Comité International Spécial des Perturbations Radioélectriques International Special Committee on Radio Interference Prof R T Kennedy EMC & COMPLIANCE ENGINEERING 13

IEC COMMITTEE of ACTION NATIONAL organisations ACEC MS BSI VDE SEV FCC ANSI CISPR TC 77 CIGRE UNIPEDE ITU ISO PRODUCT COMMITTEES CENELEC REGIONAL organisations OIML OTHERS PROFESSIONAL organisations International organisations Prof R T Kennedy EMC & COMPLIANCE ENGINEERING 14

Role of ACEC • provides advice to the Standardization Management Board (SMB) • coordinates the EMC work of IEC committees • coordinates the EMC work of the IEC with other organizations ( ITU ISO OIML ) • identifies market needs in EMC • publicises the EMC work in the IEC Prof R T Kennedy EMC & COMPLIANCE ENGINEERING 15

TC 77 – Structure and Phenomena • conducted low-frequency SC 77 A • radiated low-frequency SC 77 A • conducted high-frequency SC 77 B • radiated high-frequency SC 77 B • electrostatic discharge (ESD) SC 77 B • high power transients SC 77 C Prof R T Kennedy EMC & COMPLIANCE ENGINEERING 16

TC 77 SCOPE GENERAL EMPHASIS on EMC SC 77 A: LF Emission exclusively § Test methods as basic EMC publications § Limits for Generic & Product (Family) Standards as “horizontal publications” Prof R T Kennedy EMC & COMPLIANCE ENGINEERING 17

TC 77 SCOPE IMMUNITY: FULL FREQUENCY RANGE v SC 77 A: Low Frequency v SC 77 B: High Frequency v SC 77 C: High Power § Test Methods as basic EMC publications § Limits for Generic Standards as “horizontal publications” Prof R T Kennedy EMC & COMPLIANCE ENGINEERING 18

TC 77 SCOPE • Fundamental concepts in EMC as basic EMC publications – EM environment – Mitigation, protection, installation guides, (informative documents) • Product (family) immunity standards if required by product committees (coordinated by ACEC) • EMC Safety Prof R T Kennedy as a Horizontal Function EMC & COMPLIANCE ENGINEERING 19

CISPR • IEC Special Committee protecting radio services Why Protect Radio? • Radio is a key industry • Radio Spectrum is a limited natural resource • we all benefit from radio Prof R T Kennedy EMC & COMPLIANCE ENGINEERING 20
