Calibrated Sieves |
Description: |
The sieve is inspected in accordance with the specification. Each sieve is supplied with a calibration certificate or inspection certificates giving the range of tolerances and measurements taken. Sieving Sieving is sometimes referred to as the Cinderella of the particle-size analysis, because it performs most of the work but gets little of the credit. New high-tech processes of Sedimentation, Laser Diffraction and Image Analysis get most of the headlines. Issues affecting the universal implementation of these methods vs. sieving are high instrument cost, calibration, extensive operator training and procedural discipline. Sieving has occasionally a bad name because tests are sometimrs performed with subpar sieve mesh. Consequently, much has been made of obtaining sieves certified via ASTM or ISO mesh standards. Sieve Certification Optical approaches can accomplish this, either with a microscope or video image analysis. Results are presented in terms of maximum and minimum aperture size on the warp and on the weft, largest admissible openings and average openings. The number of openings measured is specified, means are calculated and a report is then generated. The proscribed optical certification methods examine only a small number of the openings -- usually less than 1percent. For example, a 63-micron sieve has 2.5 million apertures; the ASTM method requires less than 1000 apertures. Opening size tolerances can exceed 10 percent. A 63-micron sieve has allowable tolerances of 12 microns or almost 20 percent.
