This document (EN 131-7:2013) has been prepared by Technical Committee CEN/TC 93
5、“Ladders” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Holzwirtschaft und Mbel (Timber and Furniture Standards Committee), Working Committee NA 042-04-20 AA Spiegelausschuss zu CEN/TC 93 Leitern. Where this standard has been identified
6、by the Ausschuss fr Produktsicherheit (German Committee for Product Safety) and reference to it has been published in the Gemeinsames Ministerialblatt (German Joint Ministerial Gazette) by the Bundesanstalt fr Arbeitsschutz und Arbeitsmedizin (BAuA) (German Federal Institute for Occupational Safety
7、and Health), it is to be presumed that mobile ladders with platform which comply with this standard fulfil the relevant health and safety requirements. Where they comply with the provisions laid down in Section 5 of the Product Safety Act, such products may then be marked with the GS mark (German “s
8、afety tested” mark) as awarded to the manufacturer by an authorized “GS organization”.
