1. Scope 1.1 This test method specifies a method for the measure- ment of selected vulcanization characteristics of rubber com pounds using rotorless linear shear, unsealed torsion shear, and sealed torsion shear cure meters. The three types of instruments may not give the same results. NoTE 1- An alternative method for the measurement of vulcanization characteristics is given in Test Method D 2084. 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, any, curve responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use
