  • Changes of relevance to practice or simply cosmetic revisions?

    Experts in safety technology on the updated standard DIN EN ISO 13849-1:2016 – Safety of machinery

    After several years of standardisation work, DIN EN ISO 13849-1:2016 was published at the end of May. Since July it is therefore only this standard that is allowed to be used as the basis for the presumption of conformity. As there are a lot of changes in the standard, there may be new requirements for issuing EC declarations of conformity as a result. The effect these changes have on the practical work of machinery and plant manufacturers is explained by the seven experts in this interview. They also explain which special requirements need to be addressed on the usage of collaborative robots.
