ISO 5999 Polyurethane Foam Tensile Test Machine

ISO 5999:2013

Flexible cellular polymeric materials — Polyurethane foam for load-bearing applications excluding carpet underlay — Specification

ISO 5999:2013 specifies requirements for flexible load-bearing polyurethane foam of the polyether type.

ISO 5999:2013 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.

Some referenced standards in  ISO 5999:

ISO 2439: Flexible cellular polymeric materials — Determination of hardness (indentation technique)

ISO 1798: Flexible cellular polymeric materials — Determination of tensile strength and elongation at break

According to para 13.7, Hardness shall be measured in accordance with para  7.2 of ISO 2439 ( indentation technique).

Tensile strength and elongation at break shall be measured in accorance with ISO 1798.
