Textiles - Test methods for nonwovens - Part 11: Run-off (ISO 9073-11:2002)

ISO 9073-11 describes test methods for measuring the quantity of test liquid (simulated urine) which runs down a nonwoven test piece when a specified mass of test liquid is poured on to the nonwoven test piece superimposed on a standard absorbent media and placed on an inclined plane.
This test method is designed to compare run-off of nonwovens. It is not intended to simulate in-use conditions of finished products.
Three alternative methods are described:
Test I -- the basic method for testing hydrophilic nonwovens;
Test III -- the repeated test, with the same test parameters as in I);
Test III -- the modified method for testing hydrophobic nonwovens specifying another table inclination than in I).

Textiles - Méthodes d'essai pour nontissés - Partie 11: Écoulement sur plan incliné (ISO 9073-11:2002)

L'ISO 9073-11 décrit des méthodes d'essai pour mesurer la quantité de liquide d'essai (urine artificielle) s'écoulant d'une éprouvette de nontissé lorsqu'une masse spécifiée de liquide d'essai est versée sur l'éprouvette de nontissé posée sur un élément absorbant normalisé placé sur un plan incliné.
Cette méthode d'essai est conçue pour comparer l'écoulement des nontissés. Elle n'est pas destinée à simuler des conditions d'utilisation de produits finis.
Trois méthodes alternatives sont décrites:
Essai I -- Méthode de base pour l'essai de nontissés hydrophiles.
Essai II -- Essai répété, avec les mêmes paramètres d'essai que pour l'essai I.
Essai III -- Méthode modifiée pour l'essai de nontissés hydrophobes spécifiant un angle du plan incliné différent que pour l'essai I.

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 3.
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 part of ISO 9073 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9073-11 was prepared by Technical Committee ISO/TC 38, Textiles.
ISO 9073 consists of the following parts, under the general title Textiles — Test methods for nonwovens:
 Part 1: Determination of mass per unit area
 Part 2: Determination of thickness
 Part 3: Determination of tensile strength and elongation
 Part 4: Determination of tear resistance
 Part 6: Absorption
 Part 7: Determination of bending length
 Part 8: Determination of liquid strike-through time (simulated urine)
 Part 9: Determination of drape coefficient
 Part 10: Generation of lint and other particles in the dry state
 Part 11: Run-off
 Part 12: Demand absorbency

Textiles — Test methods for nonwovens —
Part 11:
Run-off
1 Scope
This part of ISO 9073 describes test methods for measuring the quantity of test liquid (simulated urine) which runs
down a nonwoven test piece when a specified mass of test liquid is poured on to the nonwoven test piece
superimposed on a standard absorbent media and placed on an inclined plane.
This test method is designed to compare run-off of nonwovens. It is not intended to simulate in-use conditions of
finished products.
Three alternative methods are described:
a) Test I — the basic method for testing hydrophilic nonwovens;
b) Test II — the repeated test, with the same test parameters as in a);
c) Test III — the modified method for testing hydrophobic nonwovens specifying another table inclination than
in a).

quantity of excess liquid, in grams, that runs from the test piece
3.2
percent run-off
mass of the run-off liquid, expressed as a percentage of the original mass of liquid delivered
4 Test I – Basic method for testing hydrophilic nonwovens
4.1 Principle
A specified quantity of simulated urine is discharged at a prescribed rate under specified conditions on to a test
piece of nonwoven that is superimposed on a standard absorbent media and placed on an inclined table. Any
excess liquid that runs down the test piece is collected by a standard receiver pad placed below the lower end of
the nonwoven test piece.
The run-off measures the mass of liquid collected by the standard receiver pad.
4.2 Apparatus
4.2.1 Run-off table, of acrylic glass or similar material as shown in Figure 1, the plane of which can be adjusted
to the required angle.
The table is inclined at 25° and marked with two reference black lines at 250,0 mm ± 0,2 mm distance (see
Figure 2).
The lower line (3,0 mm ± 0,2 mm from the lower end of the table) defines the position of the lower end of the
absorbent medium; the upper line (approximately 25 mm from the upper end of the test piece) defines the position
of the discharge tube axis.
4.2.2 Clip, or similar with symmetrical reference marks at 140,0 mm ± 0,2 mm (to adjust the axial position of the
test pieces).
4.2.3 Spirit level, to ensure axial discharge of the tube.
4.2.4 Support, for placing the standard receiver pad below the lower end of the test piece.
4.2.5 Standard absorbent medium, having the characteristics given below and consisting of two layers of
reference filter paper each (140 ± 1) mm × (275 ± 1) mm with the longer side in the machined direction (MD).
