Nonwovens - Test methods - Part 11: Run-off (ISO/DIS 9073-11:2024)
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).

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.
The procedures used to develop this document and those intended for its further maintenance are 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 editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of

SAFETY WARNING — This standard does not claim to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability of regulatory limitations prior to use. It is
expected that the person performing this test has been fully trained in all aspects of this procedure.
1 Scope
This test method measures the amount of test liquid (simulated urine) which runs down a nonwoven test
specimen when a specified mass of test liquid is poured on the nonwoven test specimen superimposed on a
standard absorbent medium 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
for finished products.
This present method has three options:
a) Option A - basic method for testing hydrophilic nonwovens
b) Option B - repeated test, with the same test parameters as the basic method with additional
information in
c) Option C - modified method for testing hydrophobic nonwovens specifying another degree of incline

3.1
percent run-off
percent of the original mass of liquid which runs from the test specimen
3.2
run-off
amount of excess liquid in gram that runs from the test specimen
3.3
sample
product or portion of a product taken from a production lot, identifiable and traceable back to the origin
3.4
simulated urine
testing liquid consisting of a 9 g/l solution of sodium chloride in demineralized water with a surface tension
of (70 ± 2) mN/m
3.5
test specimen
specific portion of the identified sample upon which a test is performed. 7.2 specifies the number of test
specimens needed.
4 Conditioning
Bring samples to moisture equilibrium in the standard atmosphere for testing nonwovens as directed in
ISO 139. Equilibrium is considered to have been reached when the increase in mass of the test specimen in
successive weighing made at intervals of not less than 2 hours does not exceed 0,25 % of the mass of the test
specimen.
NOTE While conditioning for a fixed time cannot be accepted in cases of dispute, it may be sufficient in routine
testing to expose the material to the standard atmosphere for testing nonwovens for a reasonable period of time
before the test specimens are tested, i.e. 4 hours.
5 Sampling
5.1 Lot Size
A lot should be established based on a logical break in the process or as prescribed by a regulation or
traceability requirements.
Test specimens being selected in accordance with NWSP 005.0, if applicable.
5.2 Sampling
If provided in the customer specification, take random sample as directed. If no requirements are provided,
ISO 2859-1 (Sampling procedures for inspection by attributes) or ISO 3951-1 (Sampling procedures for
inspection by variables) can be used. In and of themselves, these are not valid sampling plans by default. An
agreement between the purchaser and supplier requires taking into account process stability, producer’s
risk, consumer’s risk, acceptable quality level and also the cost needs to be established.
In general, if the test characteristic can be considered normally distributed, the sampling procedures for
inspection by variables will require fewer samples. However, small samples may not reflect that normal
ISO/DIS 9073-11:2024(en)
distribution and the estimated percent defective can therefore be over or under estimated. In this case, as
well as for attribute data, the Sampling procedures for inspection by attributes should be used.
