A Specification for Electronic Equipment for use in Heavy Industry

In the past inadequate attention has been paid to the mechanical design of electronic equipment for heavy industrial environments, resulting in poor life. A specification has therefore been produced which sets out the conditions the equipment will have to endure. The specification discusses general design considerations, advocating unit construction and other points which have been found of value, and insisting on adequate handbooks and circuit diagrams. Mechanical design requirements are similar to Government specifications. Typical environmental characteristics are listed and a series of proposed tests for the equipment is given. Mains supply voltage specifications are also covered.
