DESCRIPTION

BS 2782-10:Method 1005:1977


This standard BS 2782-10:Method 1005:1977 Methods of testing plastics. Glass reinforced plastics is classified in these ICS categories:
  • 83.120 Reinforced plastics

This European Standard describes a method for the determination of flexural properties of textile glass reinforced plastics in the form of rectangular bars of standard or non-standard dimensions, moulded directly or cut from sheets or other moulded shapes. It only applies to simple, freely supported beams, loaded at mid-span (three point loading test)1). The following properties may be determined using the method described:

1.1 The flexural stress and the deflection at break of materials that break before, or at, the conventional deflection.

1.2 The flexural stress at the conventional deflection of materials that do not break before, or at, the conventional deflection.

1.3 The flexural stress at the maximum force for materials that show maximum force before, or at, the conventional deflection.

1.4 The flexural stress at break or at maximum force, when the conventional deflection is exceeded, if so required by the material specification.

NOTE If the conventional deflection is exceeded it may not be possible to make direct comparison of results of flexural stress on test specimens of different thicknesses.

1.5 Optional: the apparent modulus of elasticity in flexure (modulus of elasticity determined by flexure test).

NOTE The modulus of elasticity in flexure is to be considered only as an approximate value of Young’s modulus of elasticity.
