1.1 This European Standard applies for machines and installations for stacking and de-stacking that are specifi-cally designed for building-up or taking down upright stacks of flat glass sheet by sheet including unloading and loading of single sheets of flat glass from or onto machines or transport devices (conveyors). NOTE For sketches with examples of typical constructions, see Annex A (informative), Figures A.1 to A.9. 1.2 This European Standard deals with the significant hazards, hazardous situations and events relevant to machines and installations for stacking and de-stacking flat glass when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). Those hazards which are dealt with in the ad-hoc standard EN 619 for conveyors are excepted. This European Standard speci-fies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during commissioning, operation and maintenance.1.3 This European Standard is not applicable to the significant hazards of conveyors and other machines for the manufacture, treatment and processing of flat glass, e.g. tilting tables, equipment for storage of flat glass, such as stillages. If there are specific hazards which arise by the co-operation of this machinery and equipment with ma-chines and installations for stacking and de-stacking, appropriate measures are specified. 1.4 This European Standard is not applicable to building up or taking down stacks by means of cranes that are temporarily equipped via hook with load-lifting attachments with suction cups to lift flat glass. 1.5 When compiling this European Standard, it was assumed that lifting movements are only used as part of full automatic machines and that the related hazards are not significant.
