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.

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

This document was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 6,
Meat, poultry, fish, eggs and their products.
This third edition cancels and replaces the second edition (ISO 1442:1997), which has been technically
revised.
The main changes are as follows:
— a new test method (distillation method) has been added;
— the order of the clauses of the document has been rearranged;
— the scope of the direct drying method has been modified;
— the Bibliography has been updated.
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 1442:2023(E)
Meat and meat products — Determination of moisture
content — Reference method
1 Scope
This document specifies two reference methods for the determination of the moisture content of meat
and meat products: a direct drying method and a distillation method.
The direct drying method is applicable to meat and meat products with low volatile substances in
addition to moisture.
The distillation method is applicable to meat and meat products with high volatile substances in
addition to moisture.
