Flexible cellular polymeric materials - Polyurethane foam for load-bearing applications excluding carpet underlay - Specification (ISO 5999:2007)
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 performance during a fatigue test, indentation hardness index being used as a secondary means of grading the material. 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 5999:2007)
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 Verhalten während einer Ermüdungsprüfung klassifiziert, wobei die Eindrückhärte als eine zweite 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 polymeres alvéolaires souples - Mousse de polyuréthanne pour utilisations soumises a des charges, a l'exclusion des revers de tapis - Spécifications (ISO 5999:2007)
L'ISO 5999:2007 spécifie les exigences relatives à la mousse flexible de polyuréthanne, du type polyéther, lorsqu'elle est soumise à des charges.
Elle 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 à 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.
La classification de la mousse se base sur les performances lors d'un essai de fatigue, l'indice de dureté par indentation étant utilisé comme un moyen supplémentaire pour classer le matériau.
La présente norme 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.
Les utilisations recommandées pour la série de mousses flexibles de polyuréthanne relevant de la présente norme sont indiquées dans une annexe.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 5999 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 4, Products (other than hoses).
This second edition cancels and replaces the first edition (ISO 5999:1982), which has been technically revised
(for the main details, see Annex C).

INTERNATIONAL STANDARD ISO 5999:2007(E)
Flexible cellular polymeric materials — Polyurethane foam for
load-bearing applications excluding carpet underlay —
Specification
1 Scope
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 performance during a fatigue test, indentation hardness index being used
as a secondary means of grading the material.
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.

3 Classification
3.1 Type
For the purpose 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 above types (except type RE) are subdivided into five classes based on 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
%
X Exceptionally severe 0 to 12
V Very severe 12 to 22
S Severe 22 to 32
A Average 32 to 39
L Light 39 to 45
NOTE The hardness loss ratio is calculated from the following equation:
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 that the requirements for physical
properties specified in Table 7 are met.

NOTE 1 Class A and class L materials may not be available at all high hardness levels.
NOTE 2 Reconstituted foam (type RE), because of its good fatigue properties combined with poorer compression set,
tensile strength and elongation at break properties, is specified separately in Table 8. It is generally used as thin, firm
padding or to provide reinforcement for the other foams.
Figure 2 — Fatigue classes and indentation hardness index grades — High hardness values
3.2.4 As an example, a material of initial hardness indentation index 140 N, with an indentation hardness
loss between 0 N and 17 N, is a class X material, with a hardness loss between 17 N and 31 N is a class V
material, with a hardness loss between 31 N and 45 N is a class S material, with a hardness loss between
45 N and 55 N is a class A material, and with a hardness loss between 55 N and 63 N is a class L material,
provided, in all cases, that the other property levels are achieved.
3.2.5 Any material having an indentation hardness index of 140 N and a hardness loss greater than 63 N
does not comply with the requirements of this International Standard.
3.3 Grade
Polyurethane foams are further graded by indentation hardness index, as determined by the method
described in ISO 2439, in accordanc
