ISO 11646:1993(E) 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. Esch 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. 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. International Standard ISO 11646 was prepared by the Physical Tests Commission of the International Union of Leather Technologists and Chemists Societies (IUP Commission, IULTCS). lt is based on IUP 32 published in J. Sec. Leather Tech. Chem., 73, pp. 23-24 (1989) and de- clared an official method of the IULTCS in October 1989. 0 ISO 1993 All rights reserved.

INTERNATIONAL STANDARD 0 ISO ISO 11646:1993(E) Leather - Measurement of area 1 Scope This International Standard specifies a method of measuring the area of pieces of leather. lt is intended only for the measurement of dressed and other dry flexible leathers? 2 Normative reference The following Standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the edition indicated was valid. All Standards are subject to revision, and Parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent edition of the Standard indicated below. Mem- bers of IEC and ISO maintain registers of currently valid International Standards. ISO 2419: 1972, Leather - Conditioning of test pieces for physical tests. 3 Principle The area of the conditioned leather is measured with a mechanical pin-wheel machine. 4 Apparatus 4.1 Mechanical pin-wheel area-measurement machine The machine used should preferably have a feed-roller Speed of 20 m/min & 2 m/min. The distance between the centres of the pins on two adjacent pin-wheels should preferably be 25,4 mm &- 2,5 mm, measured parallel to the axis of the pin-wheel roller-. Pin-wheel machines which do not conform to these recommen- dations may also be used, but the actual design val- ues shall be stated in the test report. 4.2 Circular calibration templet The templet shall be made of flexible reinforced ma- terial, for calibrating the pin-wheel machine immedi- ately before the machine is used. The area of the templet shall not be less than 5 % of the pin-wheel machine capacity, and the width of the templet shall not be greater than 50 % of the machine’s working width. The area of the templet shall, if possible, be within + 50 % of the anticipated area of the piece of leather - to be measured. If this is not possible, feed the same templet through the machine a number of times N without resetting the machine to zero until the total reading is within + 50 % of the anticipated test- - specimen area, and treat this total as a Single measurement. When not in use, the templet(s) shall be kept flat in the Standard atmosphere defined in ISO 2419. The area of the templet(s) shall be verified at least once a year by an independent body using measure- ment instruments traceable to a national Standard calibration procedure. The templet is acceptable if its measured area is within & 0,5 % of its nominal area. NOTE 1 Users of this International Standard are rec- ommended to keep a record book of the measurements obtained during the daily calibration pro
