Why Do Results from the Same Sieve Set and Same Sample Sometimes Differ? Causes and Remedies
Sieve analysis results may vary due to sampling errors, moisture effects, operator technique, mesh blockage, electrostatics, or sieve wear. Each factor has a measurable scientific effect—ranging from sampling variance (

AFS Sieve Grades- What is that?!
From the vast amount of choices that the user has to make to choose the right Sieve for application, I shall try to give you a rough chart of sieve selection. The most important of them is the Grade. While the ISO standard for analytical wire mesh sieve (ISO3310-1) was revised quite a while ago, the ASTM E11 followed the suite and also introduced three types of certifications for Sieves which divide them in grades. As we can see from the chart 1. Compliance grade Sieve 2. Ins
