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.
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.
This document was prepared by Technical Committee ISO/TC 94, Personal safety — Personal protective
equipment, Subcommittee SC 13, Protective clothing, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 162, Protective clothing including hand and arm
protection and lifejackets, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 13997:2023), of which it constitutes a minor
revision.
The main changes are as follows:
— Figure 7 a) was replaced;
— Footnote 2 to Figure 7 title was moved;
— the Excel file that can be downloaded using the link in the note to Table B.2 was replaced (there was a
correction because in few specific cases the Excel didn’t work as planned)

Introduction
Although textiles, composites, leather, rubbers and reinforced materials may resist cutting by sharp edges
in different ways, a test method for evaluating the resistance to cut of materials in protective clothing
needs to be applicable to all materials. The test described in this document provides a method that allows
calculations of the downwards (normal) force required to cause a blade drawn across the sample for a fixed
distance to cut through the specimen.
The performance of protective clothing materials may be classified using the numerical values obtained
from this test.

Determination of resistance to cutting by sharp objects
1 Scope
This document specifies a tomodynamometer cut test method and related calculations, for use on materials
and assemblies designed for protective clothing, including gloves. The test determines resistance to cutting
by sharp edges, such as knives, sheet metal parts, swarf, glass, bladed tools and castings.
