Leather - Chemical tests - Determination of free formaldehyde in process auxiliaries (ISO 27587:2021)

This document specifies a method for the determination of free formaldehyde, which is released under
dynamic conditions when the sample is heated in an inert dry atmosphere, in process auxiliaries for
leather. The analytical result obtained according to this procedure is expressed in milligrams per
kilogram (mg/kg) sample.

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 of the voluntary nature of standards, 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 www .iso .org/

iso/ foreword .html.

This document was prepared by the Chemical Test Commission of the International Union of Leather

Technologists and Chemists Societies (IUC Commission, IULTCS), in collaboration with the European

Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of

which is held by UNI, in accordance with the agreement on technical cooperation between ISO and CEN

(Vienna Agreement).

IULTCS, originally formed in 1897, is a world-wide 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.

This second edition cancels and replaces the first edition (ISO 27587:2009), which has been technically

revised. The main changes to the previous edition are as follows:
— the wording in 5.6, 5.7, 5.12, 7.2, 7.3, 7.4 and Clause 8 has been modified;
