Hardwood round timber - Qualitative classification - Part 2: Poplar

This European Standard specifies a qualitative classification and grade designations for felled round timber of poplar in the form of long poles or logs. The classifications describe quality classes of round timbers for which the intended use is not known. This classification is applicable to all merchantable clones of poplar.

Laub-Rundholz - Qualitäts-Sortierung - Teil 2: Pappel

Diese Europäische Norm legt die Qualitäts-Sortierung und Kennzeichnung der Klassen für gefälltes Pappel-Rundholz in Form von Langholz oder Stamm-Abschnitten fest.
Die Sortierung beschreibt die Qualitätsklassen für Rundhölzer, deren zukünftige Nutzung nicht bekannt ist. Die Sortierung gilt für alle handelsüblichen Pappelarten.

Overview

EN 1316-2:2012 (CEN) defines a qualitative classification system for felled poplar round timber in the form of long poles or logs. Applicable to all merchantable clones of poplar, the standard specifies grade designations, measurement rules and the features that determine downgrading. The classification is intended for situations where the intended end use is not yet known and supports consistent commercial grading, handling and quality control across Europe.

Key elements in the standard include:

• Standardized grade codes using the genus initial and first Latin letter plus a class character (e.g. Po-A, Po-B, Po-C).
• A grading approach based on measured dimensions and the presence, size and distribution of specific features.
• Reference measurement methods: EN 1309-2, EN 1310 and EN 1311.

Key Topics

• Grade classes: The classification divides poplar round timber into three quality classes:

  • Po-A - exceptional quality (stricter limits)
  • Po-B - normal quality
  • Po-C - lower quality; for Po-C more than 40% usable volume of the wood shall be available

• Dimensional thresholds (examples from the grading table):

  • Minimum length: Po-A 2.5 m; Po-B and Po-C 2.0 m
  • Minimum mid diameter under bark: Po-A 30 cm; Po-B 25 cm; Po-C 20 cm

• Feature limits and downgrading: A log or pole is qualified by its measured features. Failure to meet any single feature requirement results in downgrading. Notable features addressed include:

  • Sound and unsound knots (permitted sizes and frequency differ by class)
  • Simple sweep limits (e.g. < 2 cm/m for Po-A)
  • Ovality, heart shake, ring shake, frost crack
  • Rot and insect attack (permitted only in certain classes)

• Contractual culling: Certain defects (bark pocket, burl, buckle, felling shake, shear, rot, canker, etc.) may be specified as culling items by contract.

Applications

EN 1316-2:2012 is practical for stakeholders who require reliable, repeatable grading of poplar round timber, including:

• Timber merchants and log traders standardizing procurement and pricing
• Sawmills and processors planning yield, sawing patterns and downstream uses
• Quality assurance and inspection bodies performing acceptance checks
• Contracting parties that need clear contractual grading rules

The standard improves market transparency, reduces disputes and enables consistent measurement and grading practices across CEN member states.

• Measurement and terminology referenced: EN 1309-2, EN 1310, EN 1311, and the EN 844 series for terminology
