  3. European EMC Legislation (1) R&TTE Directive - DIRECTIVE 1999/5/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity In force - no revision pending however, the Directive does not explicitly control the conformity of installations, unless these are sold as a complete product. EMC Directive - COUNCIL DIRECTIVE of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility (89/336/EEC)  In force - now being revised – the revised text clarifies the conformity requirement for installations GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  4. European EMC Legislation (2) Automotive EMC Directive - COMMISSION DIRECTIVE 95/54/EC of 31 October 1995 adapting to technical progress Council Directive 72/245/EEC on the approximation of the laws of the Member States relating to the suppression of radio interference produced by spark ignition engines fitted to motor vehicles and amending Directive 70/156/EEC on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers In force - now being revised – the revised text has caused considerable debate between the automotive and telecommunication industries GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  5. European Commission Mandate M/313 The CENELEC/ETSI JOINT WORKING GROUP ON EMC OF CONDUCTED TRANSMISSION NETWORKS is responsible for preparing harmonised standards under mandate M/313 The group is to formulate immunity and emission requirements based on a common approach for CATV, power-line and telecommunications networks The group has established 2 prime tasks A and B to complete its work as described below GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  6. The CENELEC/ETSI joint working group onEMC of conducted transmission networks Task A Prepare a generic network standard to allow the demonstration of conformity of networks to the essential requirements of the EMC Directive using either: the present EN 55022 common-mode current limit up to 30 MHz and radiated limit above 30 MHz. or the common-mode current limit under 30 MHz converted to an agreed equivalent field strength limit The standard should include the measurement methods for common-mode current and for radiated fields GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  7. The CENELEC/ETSI joint working group onEMC of conducted transmission networks Task B A common modification of EN 55022 to separate Part I, product specific requirements from Part II, network specific requirements with all Network aspects moved to a new Part II. Conformance to the standard requires the appropriate connected equipment meeting the requirements of the corresponding network. Conformance may be demonstrated by applying either the generic network standard (A) or EN 55022 Part II (B) for wire-line telecommunications networks or EN 50083-8 for CATV networks GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  16. Emission Limits above 1GHZ Rationale for limit values in EMC standards The rationale for limit values in EMC standards is that they determine a safe level of emissions from radio and non-radio equipment so that radio services are protected from harmful interference The aggregate effect of large numbers of unintentional radiators from radio and non-radio equipments is to raise the ambient noise floor. For radio services an elevated noise floor means a loss of effective range or system capacity, both aspects have a detrimental effect on the quality of the radio services concerned GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  17. Liaison statement to CISPR re.spurious emissions above 1 GHz Liaison statement to CISPR regarding radiated emission limits above 1GHz, as set out in documents CISPR/I/65/CDV and CISPR/I/66/CDV The committee draft for voting CISPR/I/65/CDV specifies limits for emission from IT equipment in the range 1GHz to 6GHz. ETSI is of the opinion that the proposed limits are too relaxed to give adequate protection of current and future radio services in the 2GHz band. The limit in this range should provide the same level of protection as the current limits below 1GHz To achieve this, tighter limits are needed between 1GHz and 3GHz GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  18. ETSI Recommended Limit Values re.spurious emissions above 1 GHz ETSI recommends that the limit values already used for class A and B equipment in the current CISPR 22 standard are used for frequencies between 1GHz and 3GHz (i.e. 47dBuV/@3m for class B) For the frequency range between 3GHz and 6GHz the propagation attenuation can be taken into account. For this range we propose a relaxation of 6dB to the limits (i.e. 53dBuV/@3m for class B) In the same manner as below 1GHz, peak detector limits should be 10dB and 13dB higher for Class B and Class A respectively Above 6GHz radio services are highly directional in nature with a low probability that emissions will cause, therefore ETSI considers that emission limits in this range are not urgently needed GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA

  19. Conclusions ETSI has continued to progress the availability of EMC standards for radio and telecommunications products. In Europe the CENELEC and ETSI mandated harmonised standards offer a presumption of conformity with the relevant EMC Directives ETSI EMC standards use alternative limit values for emissions above 1GHz to those proposed in CISPR22 The free movement of goods requires compatible limit values on a global basis GSC#8 April 2003, DRAFT 0.1 - 030316GSC-8, OTTAWA
