Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating materials
These methods are for specimens either injection molded, or cut from molded or extruded sheets, plates, or shapes. The specimen rests on two supports and is loaded vertically down between the supports. This method is used to determine the flexural properties of plastics and is applicable to both rigid and semi-rigid materials.
After material is conditioned and machined to the appropriate geometry, the specimen is placed on the two outer supports that have been set to a designated span apart. Once the desired dimensional criteria is input into the software, the machine places a load in between the two supports to flex the specimen until rupture.
