Adventures of Pequeño

This is another Adventure of Pequeño: The 150 Micron Particle, I wonder why I get myself into these fantasies. However, once I start I feel constrained to press on.

In an earlier encounter, our little friend Pequeño, was on a determined quest to make it through sieves -- particularly those through which were said be too small for him to pass. In this scenario, Pequeño along with some of his family and friends -- all small particles about 150 microns in size -- are on their way to a sieve test.

In our business, we use the word “sieve” to describe a piece of equipment that separates different sized particles  using a woven wire screen. To others, “sieve” can mean something very different.

Do You Know If Your Test Sieves Are Doing the Job?

Do You Re-Certify? Compare with a Master Stack? Check with Calibration Samples?

What Does Recertification Give?

The ASTM E-11 committee has done a great job of establishing three levels of testing. These levels show the probability of a sieve’s mesh to be within the permissible variations. These variations relate to the size of openings in wire-cloth used for test sieves.
