I 2.0 OBJECTIVE: The objective of this test is- to qualify non-asbestos friction materials for normal VC usage. * iS , 3.0 INSTRUCTIONS: 1 i" Using materials submitted by. the writer, including NAFCO's UF235 (baseline),.perform automatic cast drumsdpiveline deceleration tests per the following: Drum test temperatures: 100F (wear-in thru stabilization), v/ 300F, 500F, 700F, and 100F. Drum-test speld: 3000 FPM initial velocity. Test stand inertia: 60 lb.-ft.^ Applied pressure: 75 PSI Follp^ihq ithe above testing, for potentially acceptable materials (including baseline material) / conduct wear tests per the above conditions, including all temperatures.
