ASTM D3914Standard Test Method for In-Plane Shear Strength of Pultruded Glass-Reinforced Plastic Rod
ASTM D3914 is a test method used to measure the in-plane shear strength of pultruded, glass-fiber reinforced, thermosetting plastic rod in diameters ranging from 19 to 32 mm. Shear tests of various kinds are widely used in the reinforced plastics industry to assess the strength of the reinforcement-to-resin bond in polyester-, vinyl ester- and epoxy-resin composites.
Before conducting ASTM D3914, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
