| (2) Mechanical Strength. 50 hours bump test, full of water. (3) Cooling suitability factor. This can be checked at Brooklands by the towing method, and by this means a definite figure for the limitation of the matrix can be established. Under no circumstances can a critical atmospheric temperature of less than 40°C. by this method be considered adequate. The test should always be supplemented as soon as possible by a Continental run, including high speed work in the Summer with following winds, and a test on the major passes such as the Galibier or Stelvio. (4) Loss of Water at high speeds. (5) Adequacy of Steam Passages. The car should be boiled vigorously on the dynamometer. (6) Efficiency, idling and traffic conditions. The car should be capable of idling for half an hour at an atmospheric temperature of 30°C. It should also be run, if possible, in hot weather in London traffic. (7) Mechanical Reliability of Shutters, and immunity from wind pressure effects. Wind pressure tests can be carried out on the road. The shutters should be tried out under conditions of mud, etc. Cold chamber tests should also be carried out to see if the shutters will freeze open or closed after the car has been washed. | ||
