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.
For an explanation on the meaning of ISO specific terms and expressions 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 the following URL: www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 186, Cutlery and table and decorative metal
hollow-ware, in collaboration with the European Committee for Standardization (CEN) Technical Committee
CEN/TC 194, Utensils in contact with food, in accordance with the Agreement on technical cooperation
between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 8442-5:2004), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Introduction of the term sharpness
— description of the foil pressure cutting test and foil pull cutting test
— introduction of a new evaluation method for cutting wear resistance test
— revision of the wear resistence test medium
A list of all parts in the ISO 8442 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Part 5:
Specification for sharpness and cutting wear resistance test
of cutlery
1 Scope
This document specifies the sharpness and wear resistance of knives, which are designed for professional
and domestic use in the preparation of food of all kinds, specifically of those knives intended for hand use.
This document describes test methods for sharpness measurement and for the evaluation of wear resistance
of the cutting edge.
This document does not apply for hunting knives, pocket knives, razors or tool or utility knives (with
trapezoidal blade for cutting carpets etc.). Knives with special shapes, e.g. herb chopping knives or highly
curved boning knives, can only be tested in the style of this document since not all properties and test
methods are applicable in a meaningful manner.
