Greases Oxidation Stability apparatus
Greases Oxidation Stability apparatus TT-942Z
Greases Oxidation Stability apparatus TT-942Z complies with the ASTM D942 Standard Test Method for Oxidation Stability of Lubricating Greases by the Oxygen Pressure Vessel Method.
Greases Oxidation Stability apparatus TT-942Z assesses the resistance of lubricating greases to oxidation while stored statically in an oxygen atmosphere within a sealed system at elevated temperatures under test conditions.
The primary application of the Full Automatic Biodiesel Oxidation Stability TT-14112A is to determine the oxidation stability of biodiesel, specifically Fatty Acid Methyl Esters (FAME), using an accelerated oxidation test.
The apparatus operates in full compliance with the EN 14112 standard to measure how resistant the biodiesel is to degradation under controlled conditions. This is a crucial quality control parameter to ensure the fuel remains stable during transportation, storage, and use.
Key Industries
- Lubricant Manufacturing: This is a fundamental quality control and product development test. Grease manufacturers must ensure their products have sufficient oxidation stability to meet performance specifications and provide a long service life, especially for greases intended for sealed-for-life applications or high-temperature service.
- Automotive and Heavy Equipment: OEMs in these sectors specify greases with a certain level of oxidation stability for applications like wheel bearings and constant-velocity (CV) joints. This test is used to qualify greases to ensure they will not harden, produce deposits, or fail prematurely due to oxidation.
- Aerospace and Industrial: These industries use greases in a wide range of critical applications, from aircraft components to industrial motor bearings. The oxidation stability is a key performance parameter that ensures the grease will provide reliable, long-term lubrication and not degrade in storage or service.
