Approval for measuring certification

Telecommunications

Each jurisdiction that regulates communications requires all types of equipment, and especially radio communications equipment, that are not specifically exempted (by reason of low power output, for instance) to be tested for conformance to local regulations before it is approved for use in that jurisdiction. Such conformance might include power and noise characteristics, use of permitted frequencies only, frequency stability, and various other electrical parameters.

Certificates of conformity, conformance or compliance

American commerce

A certificate of conformance is defined in American commerce as a document certified by a competent authority that the supplied good or service meets the required specifications. A certificate of conformance is a lot/datecode specific certification that provides traceability of the goods back to the point of manufacture.

American nuclear business

A certificate of conformity may be required of vendors of goods to nuclear generating stations to get the vendor to legally commit to stating compliance with applicable laws and regulations.

European commerce

A CoC or EC Certificate of Conformity is equal to a declaration of the conformity with the type approval of EC. It is produced to ensure the free movement of equipment within the European Union, specifically for equipment that is subject to homologation or registration.

A CoC is a producer’s declaration that equipment, e.g. a car or motorcycles comply with the given approved type. This document contains information about the equipment and its producer’s identification, type approval number, other technical specifications. The content of a CoC is defined by the European regulation (Amendment IX, Regulation 92/53). Equipment which do not comply with the EU specification (e.g. vehicle manufactured for the U.S. or Japanese market) and older equipment that have not been given the type approval of the EC yet, cannot have an existing CoC. Similarly, it is not possible to issue a CoC for converted vehicles; in this case another technical document might help register your car. Only car and motorcycles are eligible.

History and legislation

Certificates of conformity have been defined in EU’s Single Internal Market and Type Approval Directive (EC-92). EU’s single internal market became official on 1 January 1993. Part of the “EC-92” effort was to remove the technical barriers preventing the free movement of products within the EU market. The greatest impact of this effort has been in the area of standards in the automotive sector. The EU Commission is seeking to harmonise the automotive, technical and environmental standards between all the member states. EU legislation defines the standards in the areas of noise, particle emissions and safety. In addition, the EU’s Directive on Type Approval (EU Council Directive 92/53) eliminates the need for national type approval requirements by establishing one set of rules for automobiles and their components throughout the EU. This directive aims at the clarification of the type approval procedure for motor vehicles, separate technical units (i.e., trailers), and components.
