The Interpolation Method in Routine Detonation Testing 320029

THE AUTHOR discusses the permissible interpolation interval for use in routine detonation testing as affected by octane number, engine, and adjustment of the bouncing-pin apparatus. Test results presented show that, with suitable adjustment, the use of a 10-unit interval does not materially reduce precision although it greatly reduces the time and the quantities of materials needed for the test. To determine an economical and practical method of suitably adjusting the bouncing-pin regularly and rapidly for the use of large interpolation intervals will require further research.
