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 14268 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 289, Leather, in collaboration with the Physical Tests Commission of the International Union

of Leather Technologists and Chemists Societies (IUP Commission, IULTCS), in accordance with the

Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

IULTCS, originally formed in 1897, is a worldwide organization of professional leather societies to

further the advancement of leather science and technology. IULTCS has three Commissions, which

are responsible for establishing international methods for the sampling and testing of leather. ISO

recognizes IULTCS as an international standardizing body for the preparation of test methods for

leather.

The first edition was based on IUP 15 originally published in J. Soc. Leather Trades Chemists, 44, p. 502,

(1960) and declared an official method of the IULTCS in 1961. An updated version was published in

J. Soc. Leather Tech. Chem., 82, p. 234, (1998) and a further revision published in J. Soc. Leather Tech.

Chem., 84, p. 353, (2000) and reconfirmed as an official method in March 2001.

This third edition cancels and replaces the second edition (ISO 14268:2012), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— Introduction included;
— additional clause 3, Terms and definitions;
— additional clause 8 for the new Procedure B – Accelerated test method.

Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction

ISO 14268 describes two methods (Procedure A and Procedure B) for the water vapour permeability

determination.

— The method in accordance with Procedure A is the standard test method for water vapour

permeability determination and to be used in any case of discrepancy or dispute.
[1]

— The method in accordance with Procedure B is equivalent to the method described in ISO 20344

and can be applied for an accelerated routine control in production processes and/or if requested

by the client.
