Oct 30, 2017· Oct 28, 2017. #6. I'd say that THE standard (i.e. that which is most universal) is microns (µ). However, it's more common for places to make use of FEPA or JIS grits, or even other less common standards, and not bother stating what standard they use. Most grit standards are nearly the same in the double-digit end of the scale but begin to ...

A micron is a unit (one 10-6 of a meter) used to measure the size of particles in an abrasive material. Shopping Advice For Gem Cutting Abrasives. In the United States, most diamond compounds or powders are sold in grit sizes (50,000, 100,000, etc). Aluminum oxide and cerium oxide are usually measured in microns.
Jul 31, 2011· As for JIS vs. ANSI vs. American Standard Grit vs. Micron vs. whatever else... If you guys can find me a good source of data for them, I can whip out another graph (or two or three etc.) to show them in relation to each other. Jul 30, 2011 #13 Kentos Wiped out at 25.

The grit size numbering systems differ above 180 grit [P180], but equivalent sizes can be determined using Table 3.1. The chart shows the midpoints for the size ranges for ANSI/CAMI graded paper according to ANSI standard B74.18-1996 and for FEPA graded paper according to FEPA standard 43-GB-1984 (R1993).
The International Gem Society has great information on Microns, Grits, and Mesh, if you'd like further research. They also explain what they all mean and have conversion charts!
