ISO 13061-3 is Part 3 of the ISO 13061 series of test methods for small clear wood specimens. It specifies a method for determining the ultimate strength of wood in static bending by measuring the breaking load applied at mid-span of a simply supported beam.
Wood science and timber testing labs use it to compare the bending strength of species or lots on defect-free specimens. Its companion, ISO 13061-4, uses the same simply supported beam arrangement to determine modulus of elasticity from mid-span deflection, so the two parts can be planned together. The 2014 edition is current and was confirmed by ISO at its last review.
The test is run on a universal testing machine with a three-point bending fixture for wood specimens. Our grips and fixtures for wood testing support static bending tests to ISO 13061-3. If you need help matching ISO 13061-3 requirements to your parts or setup, contact our team.
