Mechanical Testing

    The mechanical testing sector of the Testing Laboratory accomplishes the testing of wood and its products including construction product testing in accordance with internationally recognised standards.

    The testing laboratory has been accredited by the Latvian National Accreditation Bureau LATAK in accordance with the requirements of LVS EN ISO/IEC 17025:2017 and has been assigned registration No. T-316.

    Accreditation certificate and scope available here.

    Mechanical testing sector determines mechanical characteristics of solid wood and wood based panel materials in bending, tension, compression and shear; the ultimate strength and modulus of elasticity of wood materials and structural elements for load bearing constructions; strength properties of wood materials jointed lengthwise.

    There are installed comprehensive testing devices in the mechanical testing sector with maximum loading range up to 600 kilonewtons (kN) in both tension and compression, and versatile equipment which provides wide possibilities for testing of wide range of construction products and product physically mechanical characteristics.

    Accredited testing methods according to the list of methods AD-04 (version 23):
