MEASUREMENT SERVICE

ASTM D6682-01
D6682-01

Take advantage of our over 20 year's experience in bulk solids analysis. The measurements are carried out using a certified rotary split-level shear tester in our lab. Structured process procedures ensure a high quality standard and economic workflows. Automated and customizable reports simplify to use the results.

CUSTOMER LOGIN:

The accomplishment of the measurements is up to two weeks, after receipt of the materials. Then, we submit the login data. Then, you may retrieve all the measurements and evaluations, edit or customise them according to your needs, and print or save them. The measurements are saved on the server for about 90 days.
