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

4 Measurement and volume calculation of round timber
4.1 General

Round timber measurement and volume calculation rules shall include as a minimum the following

requirements when establishing the parameters that are to be used when calculating volume. Where no

national, regional or provincial rules exist, the methods specified in Annex B shall apply.

4.2 Length
4.2.1 Apparatus

A manual or automatic measuring device shall be specified. The requirements of calibration and accuracy

shall be stated.

SIST EN 1309-2:2006
EN 1309-2:2006 (E)
4.2.2 Methods of measurement

Rules shall clearly define how the length of the following types of timber shall be measured:

– straight round timber;
– round timber with a simple sweep;
– round timber with multiple sweep;
– round timber with undercut or a butt trimming.
4.2.3 Recording results

The unit of metric measurement shall be stated. If a nominal length is required the length shall be rounded

down to the nearest nominal length. The rounding conventions shall be specified.
4.3 Diameter
4.3.1 Apparatus

A manual or automatic measuring device shall be specified. The requirements of calibration and accuracy

shall be stated.
4.3.2 Method of measurement
Rules shall define:
– where the diameter is to be measured;
– procedure when the preferred measuring point is not available;
– number of measurements to be made when using the specified apparatus;

– whether the measurement is to be taken over or under bark and any conversion methods.

4.3.3 Recording of results
The unit of metric measurement shall be stated.
When two or more measurements are taken the
