Specifies a method for determining the flexural properties of plastics under defined conditions. Used to investigate the flexural behaviour of the test specimens and for determining the flexural strength, flexural modulus and other aspects of the flexural stress/strain relationship under the conditions defined. Not normally suitable for use with rigid cellular materials and sandwich structures containing cellular material. Coverage includes definitions, apparatus, conditioning, precision and procedure. Also includes detailed tables and diagrams. AMD 8638 RENUMBERS THIS STANDARD
