ISO 2418 was prepared by the Physical Test Commission of the International Union of Leather
Technologists and Chemists Societies (IUP 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).
The Chemical and Fastness Test Commissions were consulted in the preparation of this standard. The
locations of the test specimens are identical to those given in IUP 2 published in J. Soc. Leather Trades
Chemists 42, pp. 382-385, (1958) and IUC 2 published in J. Soc. Leather Trades Chemists 49, pp. 6-8, (1965).
IUP 2 was declared an official method in 1959 and IUC 2 in 1965. Updated versions were published in J.
Soc. Leather Tech. Chem. 82, p. 194, (1998) and further revisions were published in J. Soc. Leather Tech.
Chem. 84, p. 303, (2000) and reconfirmed as official methods in March 2001. The ISO Standard differs
slightly in the text and includes tolerances for measurements but the locations of the test specimens are
identical.
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, preparation of specimens and
testing of leather. ISO recognizes IULTCS as an international standardizing body for the preparation of
test methods for leather.
This fourth edition cancels and replaces the third edition (ISO 2418:2017), which has been technically
revised with the following changes:
— a new title to more correctly explain the purpose of this document;
— definitions 3.1 to 3.4 have been added and the text throughout the document has been revised to use
the words “specimen” and “test piece” where appropriate instead of “sample” and “sampling”;
— 4.1 has been revised and re-organised. In addition, in 4.1.1 when the client identifies the part of the
