Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test me
3、thod covers the determination of the effectsof selected environments on aggregates for use in manufactur-ing sulfur polymer cement concrete (SC) and other chemical-resistant polymer concretes.1.2 The values stated in inch-pound units are to be regardedas the standard. The metric equivalents of inch-

The weighingequipment shall meet the National Institute of Standards andTechnology requirements for sensitivity and tolerances.NOTE 1In general, small quantities should not be weighed on largecapacity scales. In many applications,
10、 the smallest quantity weighed on ascale should be greater than about 10 % of the maximum capacity of thescale; however, this will vary with the performance characteristics of thescale and the required accuracy of the determination. Acceptable scalesused for weighing concrete materials preferably sh
