ASTM D 2471 : 1999

CONTAINED IN VOL 08.02, 2005 Establishes the time from the initial mixing of the reactants of a thermosetting plastic composition to the time when solidification begins.

1.1 This test method covers the determination of the time from the initial mixing of the reactants of a thermosetting plastic composition to the time when solidification commences, under conditions approximating the conditions of use. This test method also provides a means for measuring the maximum temperature reached by a reacting thermosetting plastic composition, as well as the time from initial mixing to the time when this peak exothermic temperature is reached. This test method is limited to reacting mixtures exhibiting gel times greater than 5 min.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
