The new `IEE guidelines for assuring testability´

The author introduces the material given in the guidelines to the NDE community. The guidelines are divided into three parts; general principles; technical considerations; and design rules. The first part, general principles, is for general application and includes much useful material for management on testability. The second part, on technical considerations, is product orientated and considers three areas; software, electronic devices and assemblies and electrical and electromechanical products and complex systems. In the third section, the testability is considered as an important issue in design, manufacture and in service; failure to consider it can have significant and potentially serious economic consequences; not least through product liability legislation
