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
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.

length] to [Nonwovens ― Test methods ― for nonwovens ― Part 7: Determination of bending length]
— foreword has been updated.
— Clause 1, this part of ISO 9073 has been replaced by this document.
— Clause 2, the format has been updated.
— Clause 3, the format has been updated.
— Figure 1 has been corrected according to ISO/IEC Directives, Part 2.

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.
SI values are regarded as the official standard system of measurement for this standard procedure. If
other systems of measurement are used in place of SI units (including inch-pound) their values must be
reported independently. Systems of measurement must not
