EN 15061:2007 (E) 8 Introduction This European Standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. Where for clarity an example of a preventive measure is given in this standard, this should not been considered as the only possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent level of safety is achieved. SIST EN 15061:2008
