Testing that Reaches the World
FZG Gear Testing
Clark Testing is an experienced Fuels and Lubrication laboratory providing ASTM test Methods for a wide range of industries. Our lab is operated under a rigorous ISO 17025 Quality Assurance Program which assures that testing meets our customer’s criteria for their application and industry specification.
Clark has been a leader in FZG Gear testing for over 24 years. The FZG Gear Test evaluates anti-wear characteristics and load carrying capacities of lubricants. The FZG gear test rig simulates a misaligned gear set operating in a bath of lubricant subjected to 12 increasing torque load stages. Tooth-wear is examined between stages for scuffing or scoring. The fluids performance is determined by the load stage at which excessive wear occurs. A high pass load stage indicates better resistance to scuffing.
