For each batch mix, destructive testing (molding, shear and specific gravity) verifies a product's integrity prior to production use. Established upper/lower tolerances must be met before being approved.

Baseline results & Boundary samples have determined at lab for comparison to ongoing in-house performance repeatability testing. The coefficient of friction outcome indicates proper formulation performance. Each quater or Raw material changing, we will use dyno to running the performance repeatability test and update the baesline results. Aviod environment/ material effect the final determination criterion.
