This covers everything from 'machinery', 'hazard' and 'risk' to 'adequate risk reduction', 'common cause failures' and 'common mode failures. Clause 4, 'Hazards to be taken into account when designing machinery,' can be treated as an extensive checklist of hazards, ranging from mechanical, electrical and thermal hazards to hazards generated by noise, vibration and 'neglecting ergonomic principles in machine design. Risk assessment. Clause 5, 'Strategy for risk reduction,' contains what might be termed the real 'meat' of the standard.
Sub-clause 5. Another fundamental concept that is introduced in Clause 5. These three steps are:. Beware, however, that there is a reference to the 'lowest practicable' level of risks from hazards, and the standard does not define this term.

Annex A provides a schematic representation of a machine, though this is likely to be of limited use to most readers, and there are 14 pages of a trilingual English, German and French index of specific terms and expressions used in the standard, which is unlikely to be of use to most machine designers.
The bibliography lists eleven ISO and IEC standards that machine builders may well wish to consult, though the bibliography in Part 2 is far more extensive. Part 2 of the standard Technical principles generally contains practical advice that can be implemented when designing machinery. Clauses 1 and 2 are the scope and normative reference, and Clause 3 'Terms and definitions' simply refers the reader to Part 1.
Clause 4, 'Inherently safe design measures,' gives examples of geometrical factors that should be considered. This goes into considerable detail, such as in Sub-clause 4. Clause 5, 'Safeguarding and complementary protective measures,' contains plenty of information that will be useful to machine designers on a day-to-day basis.
One example of this is Clause 5. However, machine designers should be aware that although Sub-clause 5. Cooperation at DIN.
