At the Sales Conference on the 5th, the matter of closed bodies which had been made by Windovers for testing chassis at the Works was discussed. HO. had tried one of these bodies and found that it does accentuate the chassis noises to such an extent that it is difficult to divide the different noises when a chassis is being tested. For this reason it was decided that Windovers should be requested to endeavour to reduce the noisiness of these bodies. It is to be clearly understood, however, that there should be no endeavour to so shut out from the interior of these bodies all chassis noises that when the chassisare being tested a tester might consider the chassis so silent, whereas really it is unreasonably noisy. It was decided, therefore, that these bodies should only be treated in such a way as to make them produce chassis noises to the extent that an ordinary standard limousine body might be expect to produce such noises. That is to say, the chassis should be tested with a Windover test body which will be similar to a rather bad standard closed body, so that when a chassis is being tested, it would not be passed if, to one sitting in the test body, the chassis sounded unreasonably noisy. Lest, for instance, it would be useless for the Works to sit in a body and say 'Yes, this is a nice quiet chassis' and when the chassis was fitted with a standard body for it to be found unreasonably noisy. Therefore, if a chassis is going to be noisy, it should be found to be noisy with a test body, rather than be found to be noisy when the complete standard body has been fitted. B.J. | ||
