Summary of ASTM D566:
A sample of lubricating grease contained in a cup suspended in a test tube is heated in an oil bath at a prescribed rate. The temperature at which material falls from the hole in the bottom of the cup is averaged with the temperature of the oil bath and recorded as the dropping point of the grease.
I. Main Technical Features:
1.An electric motor, heater, and heat-resistant beaker make up the oil bath. Continuous adjustments may be made to the heating power. In the oil bath, the temperature remains constant.
2. Desktop design. Really simple to use.
II. Main Technical Specifications:
1. Power supply: AC 220 V±10%, 50 Hz
2. Oil bath: 600 ml beaker.
3. Grease cup: Made of chrome plated brass. Its inner diameter is about 9.92 mm and the diameter of orifice for dropping oil is 2.8 mm. The height of the cup is about 12 mm.
4. Test tube: A tube made of heat-resistant glass with rim. Its inner diameter is 11.1 mm to 12.7 mm. There are three indentations at about 19 mm from the bottom, equally spaced on the circumstance. These indentations are used for supporting the grease cup.
5. Thermometer: -5ºC~300 ºC,scale value is 1 ºC. Its total length is 390 mm and the depth immersed is about 76 mm.
6. Heater: Tubular. Power 800 W.
7. Stirring motor: Rotating speed 60 RPM
8. Ambient temperature: -10ºC~+40 ºC
9. Relative humidity: ≤85%
10. Maximum power consumption: 900 W
11. Dimension: 350mm*180mm*410mm
