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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

This document was prepared by Technical Committee ISO/TC 38 Textiles, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile
products, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This second edition cancels and replaces the first edition (ISO 9073-13:2006), which has been
technically revised.
The main changes are as follows:
— the title has been changed from "Textiles — Test methods for nonwovens — Part 13: Repeated liquid
strike-through time" to "Nonwovens — Test methods — Part 13: Repeated liquid strike through time
(simulated urine)";
— details of blotter paper pad in 5.1 (former 4.1) and 10.3 (former 6.1) have been changed;
— Clause 10 (former Clause 6, Procedure) has been changed;
— the test report items and addition of blotter paper identification (amount and manufacturer) have
been updated;
— precision data in Annex A has been updated.
A list of all parts in the ISO 9073 series can be found on the ISO website.
