Introduction
This document has been prepared to be a harmonized standard to provide one means of conforming to
the essential health and safety requirements of the Machinery Directive and associated EFTA Regulations.
This document is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.

This document specifies the appropriate technical measures to eliminate or reduce risks arising from the
significant hazards.
This document deals all significant hazards that could occur within the expected lifetime of the machinery
including the phases of transport, assembly, dismantling, disabling and scrapping.
This document does not deal with the significant hazards arising by the use of other facilities/devices not
described in this document, that could be fitted on the machines or that can be used during the work
