Folks, The Machinery Directive MD 2006/42/EC ANNEX I states
1.4. REQUIRED CHARACTERISTICS OF GUARDS AND PROTECTIVE DEVICES 1.4.1. General requirements Guards and protective devices must: - be of robust construction, - be securely held in place, - not give rise to any additional hazard, We normally use EN 60204-1 Safety of machinery - Electrical equipment of machines - Part 1: General requirements to certify paper and mail handling machinery to the Machinery Directive. I don't really see anything in there that addressed the first and third bullets above. The OJ for MD harmonized standards lists EN 953:1997+A1:2009 Safety of machinery - Guards - General requirements for the design and construction of fixed and movable guards. I don't currently have a copy. Does anyone know if this standard addresses the above requirements? Sounds like it should. Is there any other harmonized standard to apply to meet these requirements? EN 60950-1 has requirements for flammability and mechanical strength of guards well defined but EN 60950-1 itself is not in the list of harmonized standards for the MD. It is applicable to the Low Voltage Directive and the MD does state that the requirements of the LVD apply. I'm wondering if the EN 953 standard has the same requirements in the same level of detail or if they are at least consistent. Thanks -Dave David P.
