1 Scope This standard specifies determination of the coefficient of linear thermal expansion for plastics between -30℃ and 30℃ by use of a vitreous silica dilatometer. This standard is applicable to determination of the coefficient of linear thermal expansion for plastic materials having coefficient of linear thermal expansion greater than 1×10-6℃-1 by use of a vitreous silica dilatometer. Note: at the test temperatures and under the stresses imposed, the plastic materials shallhave a negligible creep or elastic strain rate or both, insofar as these properties would significantly affect the precision of the measurements. This standard is not applicable to the materials having a very low coefficient of linear thermal expansion (less than 1×10-6℃-1). For materials having very low coefficient of expansion, interferometer or capacitance techniques are recommended.
