The Test: Four-Ball Friction & Wear Tests
| Standard |
ASTM D4172 & D5183 |
| Title |
Standard Test Method for Wear Preventive Characteristics of Lubricating
Fluid (Four-Ball Method) |
| Purpose |
This test evaluates how well the lubricant reduces wear when metal is rubbed together. |
| Description |
Three steel balls, which are immersed in the lubricant being tested, are locked into
a test cup. A fourth steel ball is placed on top of the three steel balls and is rotated at a speed
of 1,200 rpm under a 40 kgf (kilograms of force) load at 167ºF (75ºC) for one hour. After the one-hour
test period, the three stationary balls are washed and the wear scars are measured to the nearest
0.1 mm. The smaller the scar, the less the wear, and the better the lubricant. |
 |
| Results |
ICE 22 signicantly reduced the scarring of the balls. |

What does this mean to me?
- Less Scarring => Less Wear and Tear => Longer Lasting Equipment
- Less Scarring => Less Friction => Lower Energy Consumption
- Less Scarring => Less Friction => Quieter System
