STANDARDS Typical standard scopes: • standard time • standard bed size • A 4 paper size, the reference for printers, folders, envelopes and many publications • bank credit cards • business cards 3

document established by consensus approved by a recognised body for common and repeated use rules, guidelines or characteristics for activities or their results aimed at achieving optimum degree of order 4

NEED for STANDARDS 5

STANDARDS -CATEGORIES • BASIC STANDARDS • GENERIC STANDARDS • PRODUCT SPECIFIC STANDARDS 7

BASIC STANDARDS • general information / description related to the disturbing phenomena • detailed test and measurement methods • test instrumentation and basic test set up • ranges of immunity test levels • reference documents for the product committees and Generic Standards. 8

BASIC STANDARDS • specialised terminology • environment description and classification • compatibility level ranges basis for emission limits immunity test levels 9

GENERIC STANDARDS • define a set of precise EMC requirements • include limits • indicate applicable standardised tests 10

REQUIREMENTS • legal requirements control amount of EM pollution mandated by government agencies • customer satisfaction reliability imposed by product manufacturer 11

STANDARD CONTENTS OBJECTIVES measurement and test methods instrumentation test set-up ranges of test levels (immunity) NO limits NO performance criteria reference documents NO conformance testing of products GENERIC precise and essential requirements (limits) for all products intended for use in each environment residential : commercial light industry : industry refer to basic standards for test and measurement methods (no repetition) general performance criteria conformance testing of products basis for product (family) standards PRODUCT FAMILY EMC requirements for product-families specific test set-up refer to basic standards for test and measurements (no repetition) more detailed performance criteria conformance testing of products precedence over Generic Standards but co-ordinated with Generic Standards same as product-family but more specific same as specific BASIC DEDICATED PRODUCT product-family but more 22

NON-HARMONISED STANDARDS example – American Standards (UL, CSA, ANSI, Mil) Ø are NOT published in the official European Journal Ø have NOT been Adopted by European Committee for Standardisation European Committee for Electrotechnical Standardisation Ø May Require the use of a 3 rd party (Notified Body) and possibly some additional documentation between testing and placing the CE marking normally there additional costs involved Ø 39
