FAIRFAX, VA - CSC Scientific Co. Inc. is offering a paper that makes selection and use of sieves more clear.
 
Sieving in its most elemental definition is the separation of fine material from coarse material by means of a meshed or perforated surface. The technique was used as far back as the early Egyptian days as a way to size grains. In order to understand sieving today, it is essential to examine the definition of a test sieve, limitations of the test sieve procedure, test sieve standards, sieve certifications and sieve calibration.
 
Although the technique has been around since antiquity, confusion surrounds the specification of standards, certification and calibration. CSC Scientific Co. Inc. is offering a paper that will help most specifiers get the best balance of precision and operational economy by understanding the vagaries of certification types and the performance that can be expected.
 
The paper covers the limitation of sieve testing, the official standards and the certification types. It also describes the most widely used method of quality control involving the calibration of sieves to determine unacceptable wear and damage.
 
The paper will help new and experienced sieve users understand the issues that determine the best practices for individual particle size testing operations.
