C.1 Relative error Fc/Fc involved in calculating the
dimensional correction factor Fc using the
approximate equations (2), (3) and (C.2) rather than
the exact equation (C.1)
ALSO NUMBERED AS BS 2782 PART 3 METHOD 342B 1996 Specifies two methods for determining the linear dynamic mechanical properties of plastics. Gives information on the transition regions of the polymer. Also gives information about the onset of plastic flow.
