This report describes investigations to improve several fuze environmental tests from MIL-STD-331. Data measurement programs led to improvements which jolt and jumble test equipment. These programs led to improvements which resulted in longer equipment life and increased standardization of test facilities throughout DOD and GOCO plants. The data was analyzed using both time history and shock spectrum methods. Also, systems were developed to monitor the jolt machine and drop tower to verify that these facilities are conforming to the requirements of the military standard. The jolt machine monitoring system confirmed peak g-level and pulse width and the drop tower monitoring system verified projectile impact angles. Lastly, test methods such as fungus, waterproofness, salt fog, dust and vibration were updated to include recent advances in environmental test technology. Several recommendations made in the course of this investigation were accepted by the DOD Fuze Engineering Standardization Group and resulted in revisions to MIL-STD-331.
