From sean newhall of NEWPORT FAB on January 4, 2020:
An oil/grease test is done with a clear jar of water. Also a chloride test is done periodically.

From Toshihide Mori of Sasebo heavy industries, co.lud., on December 27, 2019:

Do a shipyard check prior to blasting or install blast tank.

From Marco Fabio Ramenzoni of ZINGA METALL BRASIL on December 26, 2019:
Routine checking for the cleanliness of abrasives should periodically be performed in a jar of water. In addition, one could also measure the size with a sieve analysis and the profile with a replica tape or electronic profile measure.

From Gerard Apuzzi of Champion painting on December 25, 2019:
Conduct a tape test.
