Organization: ASTM International
Publication Date: 1 December 2009
Status: inactive
Page Count: 2
ICS Code (Thermosetting materials): 83.080.10
significance And Use:

This method is significant as a process control for polymerization time.

When the cure times are determined at several temperatures and plotted as time versus temperature, different resins... View More

scope:

1.1 This test method covers the determination of the cure rate at any specified temperature for a thermosetting phenol-formaldehyde resin. The time at that temperature required to make a fluid mixture change into a hard immovable mass indicates speed of cure.

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.
