FOAMING CHARACTERISTICS OF LUBRICATING OILS

FOAMING CHARACTERISTICS OF LUBRICATING OILS – ASTM D 892 / DIN 51566 / IP 146

Model Code: SEWFC01 (Twin oil bath 4 test cylinder)
SEWFC02 (Single oil bath 2 test cylinder)
SEWFC03 (Twin air bath 2 test cylinder)
SEWFC04 (Single air bath 2 test cylinder)

This test method covers the determination of the foaming characteristics of lubricating oils at specified temperatures. This is two bath assembly with Temperature maintained at 24OC and 94.5OC. The liquid bath is used to heat the graduated glass cylinder containing sample to any temperature between ambient to 130OC. A diffuser is mounted on stainless steel or equivalent material tube is used to pass air through the heated sample. By adding cooling accessories / arrangement the test temperature of ~ 24OC is achieved and the test sequences are carried out as stated in ASTM D 892 / IP 146.
