Abstract
Overview
ISO 9120:1997 specifies the impinger method for determining the of steam‑turbine and related petroleum oils. The test estimates how quickly entrained air separates from lubricating oils under controlled conditions by saturating a sample with air, then monitoring density changes until the dispersed air content falls to . This standard is intended for comparative evaluation of an oil’s de‑aeration ability where sufficient residence time exists.
