This Standard specifies requirements for flexible load-bearing polyurethane 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, 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 Standard is not applicable to polyurethane foams foamed in place or to foams for use in heat-welded systems unless for load-bearing purposes.
