5.1 This test method provides a means of characterizing the mechanical behavior of materials using very small amounts of material. 5.2 The data obtained may be used for quality control, research and development and establishment of optimum processing conditions. The data are not intended for use in design or predicting performance. Note 2: This test method may not be suitable for anisotropic
materials.

|
1.1 This test method describes the use of linear controlled-rate-of-loading in three-point bending to determine the elastic modulus of isotropic specimens in the form of rectangular bars using a thermomechanical analyzer (TMA). Note 1: This method is intended to provide results similar to
those of Test Methods D790 or
D5934 but is performed on a
thermomechanical analyzer using smaller test specimens. Until the
user demonstrates equivalence, the results of this method shall be
considered independent and unrelated to those of Test Methods
D790 or D5934.
1.2 This test method provides a means for determining the elastic modulus within the linear region of the stress-strain curves (see Fig. 1). This test is conducted under isothermal temperature conditions from –100 to 300°C. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 There is no ISO standard equivalent to this test method. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
