ASTM E389-21

Standard Test Method for Particle Size or Screen Analysis at 4.75 mm (No.4) Sieve and Coarser for Metal-Bearing Ores and Related Materials

SIGNIFICANCE AND USE
5.1 This test method is intended to be used for compliance with compositional specifications for particle size distribution. It is assumed that all who use this procedure will be trained analysts capable of performing common laboratory practices skillfully and safely. It is expected that work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Follow appropriate quality control practices such as those described in Guide E882.
SCOPE
1.1 This test method covers the determination of the particle size distribution by screen analysis of metal-bearing ores and related materials at 4.75 mm (No. 4) sieve and coarser.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses 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.

3.1.2 nominal topsize—topsize, n—the sieve designating the upper limit or topsize shall be that sieve of the series with the smallest
openings upon which is cumulatively retained a total of less than 5 % of the sample. This defined topsize is not to be confused
with the size of the largest particle in the lot.
4. Summary of Test Method
4.1 The sample is passed through a bank of standard sieves by agitation. The screening technique described in this procedure may
be used on any solid particles that can be dried so that sieve blinding does not occur.
