DIN EN ISO 5999:2013-12 EN ISO 5999:2013 (E) 3 1 ScopeThis International Standard specifies requirements for flexible load-bearing polyureth

28、ane foam of the polyether type.It is applicable to flexible polyurethane cellular materials manufactured in block, sheet and strip form, in moulded and fabricated shapes, and as reconstituted material, used for load-bearing applications in general, but excluding carpet backing and underlay. It, thus

29、, primarily relates to the quality of polyurethane foam used for comfort cushioning purposes.The foam is classified according to the type of foam, the performance during a fatigue test, and the indentation hardness index used as a means of grading materials.This International Standard is not applica

30、ble to polyurethane foams foamed in place or to foams for use in heat-welded systems unless for load-bearing purposes.Recommended applications for the range of flexible polyurethane foams covered by this International Standard are listed in Annex A.2 Normative referencesThe following documents, in w
