ASTM D6289 Standard Test Method for Measuring Tensile from Mold Dimensions of Molded Thermoset Plastics

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D6289 standard. This test method aims to measure the shrinkage of thermoset plastics from the mold cavity to their molded dimensions when molded by compression, injection or transfer under certain conditions.

This test method allows measuring the shrinkage of thermosetting plastics from their molds both initially (within 16 to 72 hours after molding) and after aging (after extrusion at elevated temperatures).

This method will give comparable data based on standard samples and cannot predict absolute values ​​in real molded parts with varying flow paths, wall thicknesses, pressure gradients and process conditions. Differences in die shrinkage are often observed between specimen geometries described in this test method.

Initial shrinkage information of plastics is important for making molds, and post-molding shrinkage information is important to determine the suitability of the molding material for the production of thermosetting plastic components of the right sizes.

Values ​​stated in SI units should be accepted as standard. Values ​​in parentheses are for informational purposes only.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
