Purpose


The increasing cooperation between the participants of the European Schemes including both exchanging thousands of NTRs and mutual recognition of factory inspections and SMT laboratories, can lead to different opinions about the application of the standards as well as a need to wherever possible harmonise Scheme procedures :

  • In certain cases, several test methods are thus specified letting a possible choice, the reproducibility of the results obtained and the equivalence not being assured.
  • Generally, standards do not describe in details the practical procedures to carry out tests and inspections and thus let the way open to a part of freedom for interpretation and application by the testing laboratories. This may result in discrepancy in the results obtained by laboratories of different countries for the same product.
  • The application of the requirements of standards by testing laboratories may lead to the conclusion that some tests could be profitably replaced by others.
  • In many cases, new constructions in the appliances may not be completely covered by the international standards.
  • The regulations for factory inspection, SMT supervision and application of the Scheme documents and procedures need to be monitored and developed to ensure that they keep pace with developing technology. 

These considerations lead to the conclusion that it would be useful to strengthen technical exchanges between laboratory teams in order to assure the equivalence, and the same degree of severity for tests carried out by various laboratories and examine practical procedures or inspections applicable to products within the scope of the marks covered by the Schemes.


These exchanges will take place within ECS Operational Staff Meetings (OSM).

 

Tasks

 

The ECS Operational Staff Meetings are in charge of:

  • examining, in details, the practical procedures to carry out tests of conformity to standards, inspection and practical procedures in application of the CENELEC Certification Agreement so as to assure a good reproducibility of the test results and harmonisation of procedures between Scheme signatories,
  • checking the equivalence of the different testing methods proposed in standards when more than one procedure is given and examining different methods of conducting inspections and supervising manufacturer’s testing,
  • strengthening technical cooperation between testing laboratories,
  • agreeing upon common understanding and application of standards as far as the operation of Schemes is concerned,
  • proposing amendments to existing standards or procedures,
  • exchanging information regarding the provisional test schedules used by the different Certification Bodies in application of CENELEC Memorandum n° 7,
  • providing, upon request, technical advice to the ECS, the ECS Executive Committee and the EEPCA Technical Officer. Depending on the issue at hand, requests for technical advice may be addressed to an OSM collectively, by way of its Chairman, or to individual OSM members.
