| -3- AFM.{Anthony F. Martindale} Brakes. Rig Tests. All pieces to stand double the pedal load required to lock rear wheels. The servo should stand 100 hours on dynamometer, load applied for 2-3 secs. per minute at pedal load required to lock rear wheels. AFM.{Anthony F. Martindale} Road Tests. Road Tests for brakes similar to that for suspension. The brakes ought not to require re-lining under 15,000. The servo should last 50,000. IMW.{Ivan M. Waller - Head of Chateauroux} Full analysis of brake linkages, set up, and leverages, operation of safety stops, and destruction tests on road. RC.{R. Childs} Electrical Units. Specification and endurance tests on the bench, also starting tests in the cold chamber. (With respect to coil, pick up, and heating tests, under extreme conditions on the road). 50,000 miles on experimental cars. 15,000 miles in France. IMW.{Ivan M. Waller - Head of Chateauroux} General and cold chamber tests of electrical equipment, road and interior lighting. JBD.{John B. Dixon - Fuel Systems} Fuel System. Petrol pumps to be tested concurrently with other components, to obtain a value for their ultimate life. 15,000 miles French test in summer months. 5,000 miles London and suburbs with no high speed work. 30,000 miles general running in England and abroad. Of special importance is that much of the running be done in hot weather. | ||
