Detail specifications for printed circuits using various base materials, with holes either plated through or not, are in preparation. However, this standard provides general rules for drafting detail specifications by BSI Technical Committees or by component manufacturers. Although printed circuit boards are made in considerable quantities there are numerous variations in patterns with the consequent tendency to purchase only small quantities of any particular pattern. This calls for different approval procedures from those applied to most components dealt with in the BS 9000 series BS 9760 specifies tests and procedures for visual, electrical, mechanical and environmental conditions.

Part 2 Guide to the construction and installation of clean rooms, work stations and clean air devices offers advice on the selection of the various classes of clean room, pointing out that in some cases it may be more cost effective to use unidirectional flow clean work cabinets within an existing or planned clean room of a lower class rather than to build a clean room to the higher standard. General requirements for construction and fitting out are outlined, including information on layout, entryways, lighting, windows, ventillation work benches, contained work stations, fire precautions, services, vacuum cleaning equipment, furniture and anterooms. Part 3 Guide to operational procedures to clean rooms, work stations and clean procedures necessary to ensure that the environmental cleanliness are achieved clean room is in operation.

BS 5295 Environmental cleanliness in enclosed spaces is published in 3 parts by the British Standards Institution. Part 1 Specification for controlled environment clean rooms, work stations and clean air devices sets out in detail, the requirements to which clean rooms, work stations and clean air devices are to conform in order to be certain of achieving the necessary standard of cleanliness. Methods of test and of monitoring to demonstrate these levels are given, together with details of procedures and methods of working which will enable the levels to be maintained.

The NDT Centre was established at Harwell in 1967 as a ‘national centre’. It aims, with the support and encouragement of the Mechanical Engineering and Machine Tools Requirements Board (MEMTRB) to promote the wider use of NDT techniques throughout industry as an aid to improved quality assurance.
