Round timber

By employing the latest scanning technologies the specialised division „round timber“ focuses on the development of methods and models for an entirely automated measurement of round timber and for quality assurance. In the calibration and inspection sector the primary tasks lie in enforcing normative and legally binding directives regarding the determination of dimensions and regarding the receipt and acceptance of wood at this important interface between the forest industry and the sawmill, paper and wood-based panels industry.

Research and development

Electronic measurement systems for round timber – new measurement and testing methods

New measurement technologies facilitate the determination not only of length and diameter but also of other valuable and relevant geometric characteristics such as warp of round timber with high precision. Current research projects address the development as well as the evaluation of corresponding measurement and testing methods as a basis for the expansion of the existing standards and measurement regulations.

Partial debarking - technologies for automated detection of bark

In many European countries dimensions of round timber are measured ahead of debarking for reasons pertaining to torage, handling and processing speed. Partial debarking can cause problems pertaining to the determination of volume and pertaining to the sorting of timber based on its diameter into sorting boxes. In current projects, methods are being researched which allow a completely automatic assessment of the bark.

Scanning – Online quality assessment and presorting of round timber

The focus of this international research project, carrier together with an international network of partners, lies in the development of innovative scanning systems for the quality assessment for round timber. The early detection of relevant wood characteristics for the optimization of subsequent production processes is the underlying goal. By linking different scanning technologies (e.g. X-ray radiation, laser interferometry) important quality and strength-related characteristics can be determined at levels of feed speed commonly used in industry.

Characteristics and applications of local wood species

Almost half of Austria’s area is covered with forests. Apart from the main wood species, spruce, pine, beech and oak also other wood species make up a relatively small percentage. However, they are of high ecological and cultural value. Since the wood engineering properties of these lesser wood species are hardly ever known, it is difficult to find suitable applications. Thus studies were prepared in the past years on the application and use of different wood species, in particular of European black pine and Swiss pine.

Calibration, tesging and inspection

Holzforschung Austria maintains longstanding relationships with all groups which deal with round timber and obtained a lot of experience and expertise by serving these partners as an independent inspection body. As an example  Holzforschung Austria has been inspecting the receipt and acceptance of industrial grade round timber for 20 years. A cooperation agreement between the forest industry, the wood-based panel and the paper industry form the basis of this work. This field of work was substantially expanded through the accreditation of Holzforschung Austria as a calibration laboratory by the Federal Ministry of Economy, Family and Youth of the Republic of Austria (BMWA).

Scope of the accreditation:

  • Calibration of electronic equipment for measurement of round and sawn timber
  • Supervision of the receipt and acceptance of wood in the paper and wood-based panels industry
  • Supervision of the receipt and acceptance of chipped wood
  • Measurement of dimensions and of features (e.g. ÖN L1021, EN 1310)

Expert’s reports

Expert’s reports mainly focus on the suitability of different wood species and wood-based products for applications in different areas. An additional emphasis is placed on the evaluation of deficiencies caused by manufacturing processes such as the occurrence of discolorations.
