Discussion on Failure Sensitive Parameters of an EED Life Performance in Storage

An issue to distinguish sensitive parameters of storage life prior to the failure of a bridgewire electroexplosive device (EED) is studied. The degradations of bridgewire resistance, 50 % firing current, ignition delay time, bridgewire molten time and powder color with the storage time were measured under a simulating accelerated life test of high-temperature and high-humidity. The most sensitive parameter suitable to evaluate the EED storage life is discussed. It is concluded that the standard deviation of resistance change is the most sensitive degradation variable, and the next is bridgewire molten time, 50% firing current and ignition delay time. The mean of resistance is an insensitive degradation parameter.
