Polyurethane foams: the EN ISO 5999 standard

This article only wants to underline the existence of the standard:
“EN ISO 5999:2013 Flexible cellular polymeric materials - Polyurethane foam for load-bearing applications excluding carpet underlay – Specification”
This international standard specifies requirements for flexible load-bearing polyurethane foam of the polyether type.
The foam is classified according to:

  • the type (of foam);
  • the performance during a fatigue test;
  • the indentation hardness index used as a means of grading materials.
The list of recommended applications for the series of flexible polyurethane foams treated by the standard is available in appendix A (informative and non-normative), as the short abstract given below (Table A.1 - Recommended applications):
