Test Procedure

Standard FZG 12-Stage Load Test

Download the FZG 12-Stage Load Test Procedure

The standard FZG 12-stage load test is a test that had been developed for testing gear box oils. It is a dip-lubricated test and is performed on oils. According to DIN 51354 a test gear set (type A) is loaded in stages and run for approximately 15 minutes (21 000 revolutions) at each load stage under specified conditions (A/8,33/90) ie gear type A, circumferential speed of 8,33 m/s and initial sump temperature of 90 °C. The sump is filled with 1,25 litres of the test oil. During each load stage, the sump oil temperature is noted. N.B. No heat is removed (or added) by means of a heating (or cooling) coil during the test, so that the final temperature at the end of each test gives an indication of the frictional energy converted to heat. After each load stage, the gears are removed, left to cool, cleaned, weighed and visually inspected according to the procedure set out in DIN 51354 - 1970.
