The ongoing debate between the value of a sieve certification process and sieve calibration has long intrigued me.

We recently redesigned our E-commerce site. The redesign proceeded without a hitch, until we got to the sieves.

In 2011 "Powder-Bulk Solids" published an article comparing certification process veracity with a sieve calibration process using calibrated glass microspheres (or beads). The certification process merely indicates that a sieve mesh conforms to a standard that has a wide tolerance regarding mesh openings. It is performed on a small number of openings. On the other hand, calibration using the calibrated beads results in a number representing the mean opening -- a result generated by actually performing a test encompassing at least 80% of the mesh openings.
The problems outlined in the article are still dogging todays QC Managers

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.

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.

You may remember Pequeño and his family of very small 150 micron (150µ) particles being very determined to defeat sieve certification.

All about sieve Calibration
We continue to search for answers to the question "Is Sieve Calibration Really the Holy Grail?" Pequeño, you may remember him as a very small (150-micron) particle who has many similar-sized family members. They are determined to defeat Brad and his Sieve Certification.

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.
