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 ( 𝜎 𝑠 2 = 𝐶 𝑑 3 / 𝑀 σ s 2 ​ =Cd 3 /M) to reduced open area or PSD shifts. Remedies include representative sampling, moisture control, SOPs, ultrasonic cleaning, and calibrated sieves. Versatile’s ASTM E11,ISO 3310-1 stainless steel monolithic sieves ensur
