the above seems to be the industry trade organization that deals with unwanted particulates.
Issue I have always had is that they tend to deal with smaller particulates that can ready go through a particle analyzer. I was/am interested larger particles such as hair, fiber, flashing, dross "grape shot" and other particulate you tend to find on PCA. These typically are too large to go through a common particle analyzer.

Class 7 and higher does not measure the smaller particles.
Instruments that measure this level are less than $2k.
