1.1This test method covers the quantitative determination of water in new and in-service lubricating oils and additives in the range of 10  mg/kg to 100 000 mg/kg (0.001 wt./wt. to 10 % wt./wt.) using a relative humidity (RH) sensor. Methanol, acetonitrile, and other compounds are known to interfere with this test method.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3Warning—Samples tested in this test method can be flammable, explosive, and toxic. Use caution when handling them before and after testing.
