A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. 1. Scope This test method covers the determination of the compressive strength of hydraulic-cement mortars using for the test specimens portions of prisms made and broken in llcwnc in accordance with Test Method C 348. The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. Values in SI units shall be obtained by measurement in SI units or by appropriate conversion using the Rules for Conversion and rounding given in Standard IEEE ASTM SI 10 of measurements made in other units. 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. 2.
