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

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.  
1.2 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.  
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 and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 A 50 % relative humidity-equilibrated sample of known weight is allowed to fractionate on a series of various size sieves
to allow the various particle sizes to be collected on successively smaller sieve openings.
3.2 The sample fraction collected on each sieve of the series is weighed and its fractional part of the original sample is
determined.

6. Reagents
6.1 Antistatic Coating, (record cleaning spray or equivalent.)
6.2 Alcohol-Water Solution—One part ethanol to nine parts deionized or distilled water.
7. Sampling
7.1 The sample must be free-flowing and homogeneous. If particle size segregation is apparent to either the eye or from
observation under a microscope, remix and resample the material using the proper riffling procedure.
7.2 Equilibrate the sample at 20 to 25°C (68 to 77°F) in a desiccator with a humidity level of 50 %. A 24-h period is usually
sufficient.
8. Calibration and Standardization
8.1 Prior to use, check all sieves for damage or improper cleaning. If woven-wire sieves are used rather than the preferred
electroformed sieves, it is especially important to carefully inspect the wire surface for wear, misalignment, tears, creases, or
separation along the edges.
NOTE 1—Specifications for wire cloth sieves are described in Specification E11 and specifications for electroformed sieves are described in
Specification E161.
9. Procedure
9.1 Select appropriate sieves for the sample being analyzed, typically the 149, 105, 74, 44, and 20-μm sieves.
NOTE 2—For optimum results, the estimated particle size should be determined by microscopic examination at 100–300X. Sieves may then be selected
to cover the size range of the particles.
9.2 Clean 44 and 20-μm sieves prior to use in an ultrasonic bath using a 10 % ethanol, 90 % water mixture. Dry the sieves in
a low temperature air jet (hair dryer or equivalent) and allow to equilibrate at room temperature for 30 min before obtaining the
tare weights.
9.3 Tare each sieve and the fines collector pan, recording each weight to the nearest 0.001 g.
9.4 After taring, moisten a sheet of tissue paper with antistatic spray and coat the inside wall surface of each sieve by rubbing
with the coated tissue.
9.5 Place the sieves in a vertical stack in descending order by mesh size (largest on top).
9.6 Weigh a suitable amount of sample
