ASTM D1037, the Standard Test Method for Evaluating Properties of Wood-Base Fiber and Particle Panel Materials, outlines multiple testing procedures to characterize the mechanical properties of fiberboard. The internal bond test procedure is outlined in section 11 of the ASTM D1037 standard, though other sections also evaluate fastener holding, flexure properties, and compression properties in ambient or simulated environmental conditions.

Wood fiberboard is an engineered material made by using an adhesive to glue wood chips or wood particles together under high pressure, and the internal bond test of ASTM D1037 ensures that the cohesion strength of the engineered panel is sufficient for a given application. The internal bond test measures the tensile strength of the material when applying a force perpendicular to the face. This testing is especially important considering that these materials are used in construction applications and many of them are formed through the adhesion of multiple layers of material.

Materials Testing System

Most ASTM D1037 force requirements are suitable for a dual column universal testing system such as those found in Kason Electronic  Series. Required fixtures include bond test fixture and  steel specimen blocks, which were designed in compliance with the requirements of this standard.
