HARMONIZED STANDARDS IN SUPPORT OF THE ESSENTIAL HEALTH REQUIREMENTS OF THE MACHINERY DIRECTIVE - REDUCTION OF THE EMISSION OF HAZARDOUS SUBSTANCES FROM MACHINES

In support of the essential health and safety requirements of the mach inery directive concerning the reduction and assessment of dust and ga s emissions from machines, CEN TC 114 WG 15 was given the task of prep aring B1 standards. The first standard EN 626 Part 1 ''Principles for machinery manufacturers'' was published in 1994. Part 2 describes the ''Methodology leading to verification procedures''. Practicable testin g methods for the assessment of emissions of airborne hazardous substa nces from machines are defined in the B standard series EN 1093. For t he assessment the parameters emission rate, concentration, capture deg ree, separation degree and decontamination index are used. Finally, we indicate that first machine safety standards exist, so-called C stand ards, for dust measurements on electrical tools, for testing dust remo ving machines, welding fume separators and chips and dust extraction s ystems for woodworking machines; some include so-called ''achievable v alues'' based on the technical state of the art of these machines.
