However, this does not prevent compliance with relevant parts of EN 61508 being used to support a declaration of conformity with an EC product directive, if that is appropriate. But because EN 61508 is not a harmonised European standard, there is no presumption of conformity with any directive. Therefore it would be necessary to explain in the technical file how compliance with EN 61508 is being used to support compliance with specific essential requirements of the particular directive.
There are also no plans to harmonize IEC 61511 or IEC 61513 under any EC Directive, and no decision concerning IEC 61800-5-2 has yet been made. However, IEC 62061, published as EN 62061, is a transposed harmonised European standard under the Machinery Directive (an EC product directive). This has been made possible by restricting the scope of IEC 62061 to include product requirements only. Harmonization will grant a presumption of conformity with some of the essential requirements of the Machinery Directive, but will not preclude the use of other ways (eg other standards) of meeting those requirements.
