Full code of the assortment
The assortment code consists of 12 characters, where:
- The first four characters describe the assortment itself, for example, first grade pine sawlog
- The next 4 characters, from 5 to 8 (including), describe the diameter group of the assortment – from/to. For example, code 1418 describes an assortment with a diameter of 14 to 18 cm.
- The last four characters describe the assortments payable length – for example, 0360 corresponds to the assortment with the specified payable length of 360 cm.
Group of diameter and/or group of length may be omitted. In this case, omitted assortment characters are shown as “0”, for example, 111100000000, if neither group has been specified, or, 111114180000, if the group of diameter is specified but the group of length is not. Code can be shown as 4; 8 or 12 characters.
Basic code and name of the assortment
The basic code of the assortment consists of the first four characters defined by a particular structure:
[Species group][Species][Assortment group][Assortment]
A complete list of groups, species and assortments in Annex 1.
Species group – aggregates certain tree species with certain common characteristics. Three species groups are currently defined – Deciduous, Coniferous, Mixed and Other.
Species – list of species currently used in woodworking, broken down by species group.
Assortment group defines a set of assortments, sorted by their type of processing.
Assortment – the exact assortment and its name.
By using the defined assortment code structure, it is possible to describe all assortments currently used.
Diameter group
If necessary, a specific group of diameters can be specified for the assortment. In most cases, this group will be assigned to the assortment after the measurement. In some cases, this group is indicated at the beginning of the supply chain, for example, in the case of a Coniferous packing case logs 12 – 23.9 cm Ø. In this case, the Assortment code will be 101412240000.
It is also possible that no minimum or maximum diameter is specified for the diameter group. In this case:
- The first two characters are “00” if no minimum diameter is specified.
111100240000 – First grade pine sawlog, diameter up to 18 cm. No minimum diameter is specified.
- The last two characters are “99” if no maximum diameter is specified.
111128990000 – First grade pine sawlog, diameter from 28 cm. The maximum diameter is not specified.
Length group
The length group indicates the nominal (payable) length of the assortment. In most cases, this code will be determined when preparing the testing report after the measurement.
For example, 111118280360 – code corresponds to the assortment of first grade pine sawlog, diameter 18 to 28 cm, payable length – 360 cm.
Rejection codes
The classifier of the rejection codes is divided into the main and additional causes for rejection. The rejection code for the assortment is determined during the measuring. To denote a reject, it is possible to specify either the main rejection code or the main code with additional cause for rejection. Only the main rejection code is indicated mainly when measuring is done by Automated Measuring Devices where it is not physically possible to provide an additional cause for rejection.
The complete classifier of rejection codes in Annex 2.
