Machine strength-graded timber species in Spain using MiCROTEC grading machines. Version 2

This dataset contains information about the strength graded timber species in Spain using MiCROTEC S.p.A. grading machines which were approved by CEN/TC124/WG2/TG1*. It contains information about: Year Grading machine Timber species Source (origin of timber) Tickness (mm) and width (mm) of the structural timber elements to which the machine grading applies Testing type: bending (B) or tensile (T) Reference to the technical report approved by CEN/TC124/WG2/TG1 (TG/year-month/number) Reference to the specific table for the strength graded timber species of the Approved Grading Report (AGR) Strength classes type: C, D, T, ET Identification of the strength classes assigned Full reference to the technical report approved, when available It does not contain sensitive information such as the strength classes combinations and their yield or the settings to be implemented in the grading machines. The technical reports and authors, as well as the tables of the AGRs are cited, but the full douments remain confidential for CEN/TC124/WG2/TG1. This version 2 of the dataset was elaborated thanks to the collaboration between Microtec S.p.A., who provided the information for the strength graded timber using their grading machines, and InnovaWood, who collected, structured and published the dataset in the framework of the research projects EUFORE (101081788) and Woodstock (101181021). * CEN: European Committee for Standardisation | TC 124: Technical committee of timber structures | WG 2: Solid timber | TG1: Task Group 1 is a group of experts aimed to evaluate the settings for machine grading and visual grading assignements for EN 1912
