How ISO 12100 relates to type-B and type-C standardsSteve Allen, a Member of BSI's MCE/3 committee and National Sales Manager for Procter Machine Safety, has written a review of PD CEN ISO/TR 22100-1:2017, Safety of machinery – Relationship with ISO 12100 – Part 1: How ISO 12100 relates to type-B and type-C standards. This BSI Published Document is the UK implementation of European Technical Report CEN ISO/TR 22100-1:2017 and is identical to International Technical Report ISO/TR 22100-1:2015.

Steve Allen's review highlights how the term 'tolerable risk' in PD CEN ISO/TR 22100-1:2017 should be read as 'residual risk' as defined in ISO 12100-1 so as to provide compliance with EU legislation.

Other areas covered by the review include the definitions of type-A, type-B and type-C machinery safety standards, and a flow diagram showing the recommended steps for using ISO 12100 and type-B and type-C standards. Steve Allen says this diagram will be particularly helpful when all or some of the hazards present on the machine are addressed by a type-C standard.

The review refers to the fact that PD CEN ISO/TR 22100-1:2017 contains no guidance on how or where to search for appropriate type-C standards, but it does provide a helpful overview of the type-B standards, grouped into hazard categories, aspects and technologies (eg noise, safety devices, dimensions and distances, etc).
