ASTM C285-88 (Re-approved 1994) Standard test method for sieve analysis of wet milled and dry milled porcelain enamel, for determination of the fineness of frit in wet-or dry-milled porcelain enamels and other ceramic coatings on metals by use of the number 200 or No 325 mesh, 212 ASTM C925-79 (Re-approved 1995) Standard test method for precision electroformed wet sieve analysis of non-plastic ceramic powders, for particle size distribution determination ofpulverized alumina and quartz for particle sizes from 45 pm to 5 pm by wet sieving, 212, 230... 

Dry and wet sieve analysis can be conducted according to ASTM Cl 10-95b, sec. 5, Standard Test Methods for Physical Testing of Quicklime, Hydrated Lime and Limestone. Sieve analysis of magnesia powders finer than 100 mesh (U.S. Standard Sieve Series) can be performed using ASTM C110-95b, sec. 20. 

Particle size analysis of plastic pellets is important in molding and extrusion of materials with special reference to dust particulates. Standard test methods were found insufficient for this purpose and a special method was developed employing wet sieve analysis. This method gives superior data compared with the usually used dry sieve process. ...

SatnpCe Preparation. Seventy grams of sample, previously calcined at 538°C, was dispersed in about 125 mL of sodium metaphosphate solution and "wet screened" using a sieve stack of 250, 270 and 325 mesh, 8-inch diameter sieves. The sieves were washed with water until the effluent was free of any particulate and then rinsed with acetone to de-water. After air drying, the contents of each sieve were transferred to a porcelain dish and the material was recalcined at 538°C. Appropriate weights taken during this procedure allowed for the determination of percent moisture in the starting material and sieve analysis relative to the appropriate sieve fractions. The total +325 mesh material was recombined and mixed for the test. 

Complete instructions and procedures on the use and calibration of testing sieves are contained in ASTM STP447B [7]. Contents include analytical methods, information relating to wire mesh, perforated plate and micromesh sieves, dry and wet testing and other methods. This publication also contains a list of all published ASTM standards on sieve analysis... 

Many industries have large data banks on product size distributions by sieve analysis and want to continue using this form of presentation. In order to accommodate this need Cho et. al. [48] converted Sedigraph data to sieve data using wet screened powder in the 38 to 53 pm size range and fitted the data to a logarithmic distribution to give the slope and median size. This procedure must be use with caution since the conversion factors are shape dependent and a new calibration is required for each product. 

Sediment samples were thawed and mixed to ensure homogeneity. The dry weight and percent water content of the sediments were determined by drying approximately 5 g of the sediment at 105-110°C for several hours until a constant weight was reached. Grain-size distribution was determined by wet sieving and pipette analysis.

Molecular sieves belonging to alumino phosphate with an AEL structure and its derivatives were prepared by hydrothermal synthesis as per the literature [10]. Composition of these samples was established by wet chemical analysis methods by using atomic absorption (Hitachi, Japan ) and inductively coupled plasma spectroscopy ( Jubin Yuan, France ). Different degrees of alkali exchanged Y type zeolites were also prepared from Linde NaY by the ion-exchange procedure. Characterization of the catalysts and the experiments are carried out as discussed in the publication [11]. 

To ensure uniformity, sediments were thoroughly mixed before use. The ICS was wet-sieved through a 1.0-mm sieve, followed by resuspension in distilled water and mixing on a ball mill for 2 hr. The intercalibration sediment was then filtered to remove most of the water. Other sediments were thoroughly mixed by hand. Replicate analysis of aliquots of these sediments showed subsampling variability was small (Table II).
