Historical Standard: ASTM D731-08 Standard Test Method for Molding Index of Thermosetting Molding Powder
SUPERSEDED (see Active link, below)
ASTM D731
1. Scope
1.1 This test method covers the measurement of the molding index (plasticity) of thermosetting plastics ranging in flow from soft to stiff by selection of appropriate molding pressures within the range from 530 to 5300 psi (3.7 to 36.5 MPa).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
Note 1There is no ISO standard equivalent to this test method.
