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 9073-18 was prepared by Technical Committee ISO/TC 38, Textiles.

Part 18:
Determination of breaking strength and elongation of
nonwoven materials using the grab tensile test
1 Scope
This part of ISO 9073 specifies a grab tensile test procedure for determining the breaking strength and
elongation of most nonwoven materials. It includes instructions for the testing of wet specimens.
This grab tensile test procedure is applicable for most nonwovens, but is not recommended for nonwovens
which have a high percentage of stretch.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

ISO 186, Paper and board ― Sampling to determine average quality
ISO 10012:2003, Measurement management systems ― Requirements for measurement processes and
measuring equipment
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
grab test
tensile test in which only the centre part of the test specimen is gripped in the jaws of the testing machine
NOTE Normally, the grab tensile strength is determined using a 100 mm wide strip of material. This tensile load is
applied at the midpoint of the 100 mm specimen. This is done using 25 mm wide jaw faces that are used to clamp the
specimen at each end.
3.2
elongation
deformation in the direction of load caused by a tensile force
NOTE Elongation is generally expressed as a percentage, as a ratio of the length of the stretched material to the
length of the unstretched material. Elongation may be determined by the degree of stretch under a specific load, or the
point where the stretched material breaks.
ISO 9073-18:2007(E)
3.3
breaking force
maximum force applied to a material when it is carried to rupture
NOTE Materials that are brittle usually rupture at the maximum force. Materials that are ductile usually experience a
maximum force before rupturing.
3.4
tensile strength
strength of a material when subjected to either pulling or compressive stress
NOTE It measures the stress a material can bear without breaking or tearing.
4 Principle
Using a tensile testing machine, mount a 100 mm wide specimen centrally with 25 mm clamps at each end of
the specimen. The tensile testing machine applies force until the specimen breaks. Values for the breaking
force and the elongation of the test specimen are obtained from tensile test instruments by recording charts,
or a computer interface.
This test is performed to simulate the stress a medical doctor would place on the elbow of his surgical gown or
other similar pressure points. This stress on the elbow of the surgical gown is n
