This European Standard defines technical principles and specifications, to help designers and manufacturers in achieving safety in the design of machinery (see 3.1 in EN 292-1) for professional and non-professional purposes. It may also be used for other technical products having similar hazards. Part 1 and 2 should be used together when considering the solution to a specific problem. They can be used independently of other documents, or as a basis for the preparation of other type A standards or type B and C standards. EN 292-2 in conjunction with part 1 would also assist in a preliminary assessment of machines with regard to their safety, where there is no relevant type C standard available. It is recommended that this standard is incorporated in training courses or in manuals to convey technical principles and specifications to designers, etc.
