Sieve Calibration Is the Holy Grail!

Yes Harry, there is a Santa Claus. Or, more specifically, there really is a Holy Grail for ensuring consistent particle size analysis. 

If you’ve been following along, you know it was proven by Pequeño and his family of 150 micron particles who tried to bust our friend Harry’s quality control by attempting to slip through the mesh in Harry’s test sieves and defeat sieve certification.

(If you missed this drama, check out previous posts in the Holy Grail series.)

Now that we have indeed confirmed that, yes, sieve calibration really is the Holy Grail that sieve testers have been looking for, let’s get to work and dive a little deeper. Let’s examine some methods of sieve calibration.

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.

Who Cares About Sieve Testing ?

In one of my more contemplative moments, I thought a bit of history about particle size analysis would be of interest. So let’s see Who Cares About Sieve Testing.
