Vacuum Measurements and the Community Bureau of References (BCR) By the Council Decision of 18 June 1973", a programme of research has been drawn up for the European Economic Community in the field of reference materials and methods (Community Bureau of References (BCR)) for a period of 3 years starting on 1 January 1973. The object of the Community programme is to support, group, dovetail and supplement the work of the member countries. The programme comprises: (a) operation of a secretariat; (b) - - characterization of materials; - - inventorying and defining requirements for new certified reference materials (CRM); - - establishment of technical specifications of CRM; --

development and assay of CRM;

--

organization of inter-laboratory comparisons;

--

European certification of technical characteristics of CRM;

- - approval of laboratories. The nature of these activities will vary from one sector to another, depending on requirements. They may entail: --

exchanges of information between private and public national organizations about requirements and availabilities of existing CRM;

--

co-ordination of work between these organizations;

--

financing of the cost of the above activities e.g. by placing contracts with participating laboratories in the member countries;

--

utilization of the Commission's Joint Research Center facilities to supplement and expand national activities.
