ASTM C308-00(2012)e1
(Test Method)Standard Test Methods for Working, Initial Setting, and Service Strength Setting Times of Chemical-Resistant Resin Mortars
Standard Test Methods for Working, Initial Setting, and Service Strength Setting Times of Chemical-Resistant Resin Mortars
SIGNIFICANCE AND USE
4.1 These test methods offer a means of determining the working time, initial setting time and service strength setting time of chemical-resistant resin mortars. The results obtained should serve as a guide in, but not as the sole basis for, selection of a chemical-resistant mortar for a particular application.
SCOPE
1.1 These test methods cover the determination of the working, initial setting, and service strength setting times of chemical-resistant resin mortars.
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.
