Standard Test Method for Determination of Moisture in New and In-Service Lubricating Oils and Additives by Relative Humidity Sensor
 N D7546

Annotation

This 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.

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

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

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Метод стандартной пробы для определения влажности в новых и штатных смазочных маслах и добавках датчиком относительной влажности

Этот метод испытаний покрывает количественное определение воды в новых и штатных смазочных материалах и добавок в диапазоне от 10 мг/кг до 100 000 мг kg (0.001 веса wt. к 10%-му весу/весу.) использование датчика относительной влажности (RH). Метанол, ацетонитрил и другие комплексы, как известно, вмешиваются в этот метод испытаний.
