ASTM D91

ASTM D91 is the standard test method for the precipitation number of lubricating oils.

Your customers agree on acceptable specs and delivering on spec is important for your business’ reputation, and for the continuation of those contracts.

Labs like yours manage several distributor relationships to make sure technicians are equipped with the supplies and instruments to keep ASTM D91 tests running as needed, and that distributor management is an unnecessary burden.

We curated a collection of the supplies for your ASTM D91 tests, so you can get most of the supplies your lab needs in one place.

ASTM D91 covers the determination of the precipitation number of steam cylinder stocks and black oils, and can be used for other lubricating oils.
