In addition machinery should comply as appropriate with EN 292-2 : 1991 for hazards which are not covered by this standard. This standard contains safety requirements for roughing, scouring, polishing and trimming machinery. It is aimed at designers, manufacturers and importers. 1 Scope 1.1 This standard applies to the following machines which are intended to work material for the manufacture of footwear: ± automatic and manual roughing, scouring and polishing machines; ± automatic and manual edge contour trimming machines. 1.2 This standard does not apply to modular shoe repair machines. 1.3 This standard specifies safety requirements for design, construction and operation. It takes account of intended use, foreseeable misuse, component and system failure. 1.4 This standard covers all hazards relevant to the footwear, leather and imitation leather goods manufacturing industries. The use of machines within the scope of this standard in different industries may give rise to hazards which were not taken into account at the time of its preparation. 1.5 This standard applies to machines manufactured after its date of issue. 2 Normative references This European standard incorporates by dated or undated reference provisions from other publications.
