NF EN ISO 5999

<p>ISO 5999:2007 specifies requirements for flexible load-bearing polyurethane foam of the polyether type.</p> <p>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.</p> <p>The foam is classified according to performance during a fatigue test, indentation hardness index being used as a secondary means of grading the material.</p> <p>The standard is not applicable to polyurethane foams foamed in place or to foams for use in heat-welded systems unless for load-bearing purposes.</p> <p>Recommended applications for the range of flexible polyurethane foams covered by the standard are listed in an annex.</p>
