EN ISO 12100

Safety of machinery. Basic concepts, general principles for design. Pts 1 & 2

This is an A standard which outlines all the basic principles including risk assessment, guarding, interlocking, emergency stops, trip devices, safety distances, etc. It references to other standards that provide greater levels of detail.

In the near future it is likely that EN ISO 12100 and EN ISO 14121 will be combined into one standard.

EN ISO 14121

Principles for risk assessment.

This principle outlines the fundamentals of assessing the risks during the life of the machinery. It summarizes methods for hazard analysis and risk estimation.

An ISO Technical Report: ISO/TR 14121-2 is also available. It gives practical guidance and examples of methods for risk assessment.
