Significance and Use
5.1 This test method provides data for assessing compliance where specifications limit the amount of material retained when sieved on a 45-µm (No. 325) sieve.
1.1 This test method covers the determination of the fineness of hydraulic cement by means of air jet sieving using a 45-µm (No. 325) sieve by Air Jet sieving.
1.2 The values stated in SI units are regarded as the standard. The values given in parentheses after SI units 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
