Foreword
This document (EN 1309-2:2006) has been prepared by Technical Committee CEN/TC 175 “Round and sawn
timber”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by September 2006, and conflicting national standards shall be
withdrawn at the latest by September 2006.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.

Introduction
There are many different round timber measurement and volume calculation rules in Europe. These have
come into being based on historical influences and traditions. Much sawmilling and forestry data is based on
these differing rules. Because of the diversity of existing rules in different countries, and in some cases
between different regions in the same country, it is currently impossible to lay down a single set of acceptable
rules for all member states.
This standard therefore gives basic principles which are to be followed when drawing up round timber
measurement and volume calculation rules. Examples of rules currently in use and which meet these
principles are listed in Annex A. Annex B applies where no national, regional or provincial rules exist.
This standard is one of a series, being methods of measurement for round timber and sawn timber. Other
standards in this series are:
EN 1309-1, Round and sawn timber – Method of measurement of dimensions - Part 1: Sawn timber
EN 1310, Round and sawn timber – Method of measurement of features
EN 1311, Round and sawn timber – Method of measurement of biological degrade
EN 1315-1, Dimensional classification – Part 1: Hardwood round timber
EN 1315-2, Dimensional classification – Part 2: Softwood round timber
1 Scope
This European Standard defines the principles which are to be used in the derivation of round timber
measurement and volume calculation rules. This standard applies to rules for measuring hardwood and
softwood felled round timber. It does not apply to tropical timber.
