ASTM Standard

# ASTM D4513

Standard Test Method for Particle Size Distribution of Catalytic Materials by Sieving

[Back to all techniques](/analytical-techniques/)

## Significance and Use

4.1 This test method can be used to determine particle size distributions of catalysts and supports for materials specifications, manufacturing control, and research and development work.

## Scope

1.1 This test method covers the determination of particle size distribution of catalytic powder material using a sieving instrument and is one of several found valuable for the measurement of particle size. This test method is particularly suitable for particles in the 20 to 420 μm range. (See Terminology D3766.)

1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1 Exception—In 5.2, mesh size is the standard unit of measure.
