Petroleum and related products. Determination of air-release properties of steam turbine and other oils. Impinger method Ingestion-build-266356 ISO/IEC 21471 applies to all1 Scope This International Standard specifies a method for the estimation of the ability of a petroleum type steam turbine oil to be separated from entrained air. NOTES 1 The impinger method described in this International Standard is used for determining the air release ability of the oils tested. Air bubbles dispersed in the oil influence the compressibility and can cause malfunctions. This method may not be suitable for ranking oils in applications
