    Abstract - (Show below) - (Hide below)

    A method for obtaining specimens with high or low levels of reversion (shrinkage in response to heat treatment).

    Scope - (Show below) - (Hide below)

    This part of ISO 2557 specifies the procedure for the preparation of test specimens with predominantly monoaxial orientation in the form of rectangular plates, made from rigid amorphous thermoplastic material. Cellular plastic materials and fibre-containing plastic materials are excluded.

    The rectangular plates may be used for impact testing by the falling weight method.

    Bars cut from the plate in different directions may serve as test specimens for the determination of the dependence of mechanical strength upon the degree and direction of the predominant orientation in the plate.
