HALT (Highly Accelerated Life Testing)
HALT is used by Basler Electric to prove that our products will provide the user with many years of
reliable service. HALT subjects the device to extremes in temperature, shock, and vibration to simulate
years of operation, but in a much shorter period. HALT allows Basler Electric to evaluate all possible
design elements that will add to the life of this device. As an example of some of the extreme testing
conditions, the DECS-250 was subjected to temperature tests (tested over a temperature range of –100
to +120°C (–148 to +248°F)),
vibration tests (of 5 to 45 G at +20°C (68°F)), and temperature/vibration
tests (tested at 40 G over a temperature range of –100 to +120°C (–148 to +248°F)). Combined
temperature and vibration testing at these extremes proves that the DECS-250 is expected to provide
long-term operation in a rugged environment. Note that the vibration and temperature extremes listed in
this paragraph are specific to HALT and do not reflect recommended operation levels.
