Price based on 1 page Copyright International Organization for Standardization ted without license from IHS Not for Resale FOREWORD ISO (the International Organization for Standardization) is a worldwide federation of national standards institutes (ISO Member Bodies). The work of developing International Standards is carried out through ISO Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up 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. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the ISO Council. Prior to 1972, the results of the work of the Technical Committees were published as ISO Recommendations; these documents are now in the process of being transformed into International Standards. As part of this process, Technical Committee ISO/TC 55 has reviewed ISO Recommendation R 737 and found it technically suitable for transformation. International Standard ISO 737 therefore replaces ISO Recommendation R 737-1968 to which it is technically identical. ISO Recommendation R 737 was approved by the Member Bodies of the following countries : Australia Hungary Portugal Belgium India Romania Canada Ireland South Africa, Rep. of Czechoslovakia Israel Spain Italy Sweden Denmark Egypt, Arab Rep. of Japan Turkey Finland Netherlands United Kingdom France New Zealand U.S.S.R. Germany Poland Yugoslavia Body of the following country expressed disapproval of the The Member Recommendation on technical grounds : Austria The Member Body of the following country disapproved the transformation of ISO/R 737 into an International Standard : Austria @ International Organization for Standardization,1975 Printed in Switzerland Not for Resale INTERNATIONAL STANDARD ISO 737-1975 (E) Coniferous sawn timber -- Sizes -- Methods of measurement 1 SCOPE AND FIELD OF APPLICATION c) unedged timber : in the middle of the length of the sawn timber: the width is expressed as half the sum of This International Standard defines methods of the widths of both faces in the case of sawn timber of measurement of thickness, width, length and volume of 40 mm (1.574 8 in) and greater in thickness; in the case coniferous sawn timber. of sawn timber less than 40 mm (1.574 8 in) thick, the width is measured on the narrow face. It covers unplaned square-edged and unedged coniferous sawn timber Measurements of the width of sawn timber given in 2.2 b) Terms and definitions are given in IS0 1032. and c) above are rounded up or down to the nearest multiple of 10 mm (0.3937 in), with 5 mm (0.1968 in) rounded to themultipleof 10 mm (0.3937in)above. 2 METHODS OF MEASUREMENT 2.1 The length of sawn timber is the minimum distance 2.3 The thickness of sawn timber is measured at any place between its ends, sawn (conventionally) perpendicularly to on the length of the piece, but not less than 150 mm the longitudinal axis of a piece. (5.9055in)fromtheends. 2.2 The width of sawn timber is measured in the following way : 2.4 The volume of each piece of sawn timber is the a) square-edged timber with parallel edges : at any place product of the nominal thickness, width and iength of sawn on the length of the sawn timber where there is no wane, timber,expressed in the same units of measurement.
