Abstract : The object of this investigation was to examine the operation of the Raymond 1060 timers under the environments of high and low temperature, steady-state acceleration, vibration and shock. At low temperatures (to -96 F) the maximum increase in time delay was 5.8%, as compared to 26.6% in the 'Phase II' modified 60 second timer, and 55.5% for the earlier model. Steady state accelerations of 100 'G's' caused a maximum increase in time delay of 12% in the worst direction, compared to a complete stalling of the 'Phase II' model at 12.5 'G's' in the worst direction and stalling at as low as 70 'G's' for the earlier model. Prolonged vibration caused a slight but permanent reduction in time delay. Shock and high temperature had no visible effect on the specimen timers.
