Oil Separation of Lubricating Grease
Oil Separation of Lubricating Grease TT-1742
Oil Separation of Lubricating Grease TT-1742 adheres to the ASTM D1742 Standard Test Method for Oil Separation from Lubricating Grease During Storage.
This equipment assesses the propensity of a lubricating grease to release oil while stored in containers, whether fully or partially filled. It is not applicable for greases softer than NLG1 No.1 grade. The procedure involves placing the grease sample on a 75-μm (No.200) sieve and subjecting it to 1.72kPa (0.25psi) air pressure for 24 hours at 25°C (77°F). Any oil leakage is collected in a beaker and quantified by weight.
1. The digital pressure gauge shows the pressure reading.
2. A high-precision needle valve regulates the pressure.
3. The temperature is displayed digitally by a temperature controller.
4. The compressor cooling system is completely enclosed and features internal circulation.
1. Test units: 2
2. Temperature control: 25°C ± 1°C
3. Pressure range: 1.72kPa ± 0.07kPa
4. Sieve aperture: 75μm
5. Pressure display: Precision digital pressure gauge
6. Cooling method: Completely enclosed compressor cooling
