Tamson CEC L-109-14 bath
CEC L-109-14 bath

Tamson is manufacturing a CEC L-109-14 bath. The CEC L-109-14 test method covers the oxidation test for engine oils operating in the presence of biodiesel fuels. As it is expected that more biodiesel will be blended with diesel in the future, the objective of this oxidation test is to provide preventive protection against the consequences of biodiesel induced engine oil oxidation. The selected test conditions should take the different usage patterns and engine hardware of passenger cars and commercial vehicles into account. Tamson can supply a complete CEC L-109-14 bath, complete with glassware and flowmeters, as is needed for this test.

For more information, please see our specification sheet.
New ASTM D1298 video
Tamson has made a video on the ASTM D1298 apparatus. The Tamson ASTM D1298 apparatus consists of a rack with jacketed cylinders and a chiller. The rack with jacked cylinders gives a better view of the hydrometer, compared to a bath with cylinders. This because a bath blocks the view for a part of the hydrometer. With our ASTM D1298 apparatus, you will have a clear view of the hydrometer while the sample is kept at the test temperature.
