D892 and D6082 Dual Twin Foaming Characteristics Test Apparatus

Foaming of lubricating oils in applications involving turbulence, high speed gearing or high volume pumping can cause inadequate lubrication, cavitation, overflow and premature oxidation. The sample is blown with a controlled volume of air at different specified temperatures. The resultant foam is measured at the end of each aeration period and at different intervals afterward. The amount of time required for the foam to collapse to “0” after the aeration period is also measured. For four tests in accordance with control ASTM D6082 and ASTM D892 specifications. Dual liquid baths feature digital temperature control for Sequences I through IV. Four flowmeters maintain the required flow rate of 94 and 200mL/min to the air diffusers. Requires the use of an external chiller to perform the Sequence I and III tests at 24°C.
