Flexible cellular polymeric materials - Polyurethane foam for load-bearing applications excluding carpet underlay - Specification (ISO 5999:2013)
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.
Weich-elastische Polymerschaumstoffe - Polyurethanschaumstoffe für Polsterzwecke mit Ausnahme von Teppichunterlagen - Anforderungen (ISO 5999:2013)
Diese Internationale Norm legt Anforderungen an weich-elastische, tragende Polyurethanschaumstoffe vom Polyethertyp fest.
Sie gilt für weich-elastische Polyurethanschaumstoffe, die als Schaumblock, in Platten- und Streifenform, als Formkörper und angefertigte Schaumstoffteile sowie als rekonstituiertes Material für allgemein tragende Anwendungen, mit Ausnahme von Teppichrückseiten und -unterlagen hergestellt werden. Die Norm bezieht sich folglich in erster Linie auf die Qualität von Polyurethanschaumstoffen zur Anwendung für Polsterzwecke.
Der Schaumstoff wird entsprechend dem Schaumstofftyp, dem Verhalten während einer Ermüdungsprüfung und dem Eindrückhärte-Index klassifiziert, der als eine Möglichkeit zur Einstufung des Materials dient.
Diese Internationale Norm gilt weder für Hinterschäumungen noch für Schaumstoffe zur Verwendung in heißgeschweißten Systemen, außer für tragende Anwendungen.
Empfohlene Anwendungen für den Bereich weich-elastischer Polyurethanschaumstoffe entsprechend dieser Internationalen Norm sind in Anhang A aufgeführt.
Matériaux polymères alvéolaires souples - Mousse de polyuréthanne pour utilisations soumises à des charges, à l'exclusion des revers de tapis - Spécifications (ISO 5999:2013)
L'ISO 5999:2013 spécifie les exigences relatives à la mousse flexible de polyuréthanne, du type polyéther, lorsqu'elle est soumise à des charges.
L'ISO 5999:2013 s'applique aux matériaux alvéolaires souples en polyuréthanne fabriqués en blocs, en feuilles ou en bandes, en formes moulées ou fabriquées et comme matériau de récupération, employés d'une façon générale pour des utilisations soumises à des charges, mais à l'exclusion des dos et revers de tapis. Elle se rapporte donc en premier lieu à la qualité de la mousse flexible de polyuréthanne utilisée à des fins de rembourrage visant le confort.
L'ISO 5999:2013 ne couvre pas les mousses de polyuréthanne formées en place, ou les mousses à l'usage des systèmes soudés à chaud, sauf pour des utilisations soumises à des charges.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

3 Classification
3.1 Type
For the purposes of this International Standard, flexible polyurethane foams are classified in accordance
with Table 1.
Table 1 — Types of foam
Type Description of foam
LB Block foam, slabstock or contour cut [low resilience (known as “viscoelastic”)]
I MB Block foam, slabstock or contour cut (conventional)
HB Block foam, slabstock or contour cut (high resilience)
LM Moulded [low resilience (known as “viscoelastic”)]
II MM Moulded (conventional)
HM Moulded (high resilience)
III RE Reconstituted or bonded
3.2 Class
3.2.1 Materials of the types of foam listed in Table 1, except for type MM (see footnote b to Table 7) and
RE (see footnote a to Table 8), are subdivided into five classes based on the performance in the constant-
load pounding test described in ISO 3385.
3.2.2 The five classes, their intended types of service and their intended hardness loss ratio are given
in Table 2.
Table 2 — Classes and intended types of service
Hardness loss ratio
Class Type of service
P (%)
X Exceptionally severe 0 ≤ P < 12
V Very severe 12 ≤ P < 22
S Severe 22 ≤ P < 32
A Average 32 ≤ P < 39
L Light 39 ≤ P < 45
NOTE The hardness loss ratio is calculated from the following formula:
HF−
P = ×100
H
where
P is the hardness loss ratio (%);
H is the initial hardness index (N);
F is the final hardness index (N).
3.2.3 Classes X, V, S, A and L are defined by the indentation hardness loss over the range of hardness
index values from 0 N to 650 N, as shown in Figures 1 and 2, provided the requirements for physical
properties specified in Table 6, Table 7 and Table 8 are met.

thin, firm padding or to provide reinforcement for the other foams.
