Description / Abstract:
This International 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 International Standard is not applicable 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.
