When choosing between MIL-HDBK-217 and Telcordia SR-332, also keep these points in mind: - Telcordia has 6 environment classifications (4 ground, 1 air, 1 space), while 217F2 has 14 environments (3 ground, 8 air, 1 space, 2 sea). Based on reports from our customers, Telcordia seems to give much more realistic results than 217, and Telcordia predicted MTBF results are likely to be more consistent with actual field experience. Our informal tests comparing 217 and Telcordia MTBF predictions indicate that Telcordia results are usually much better (we saw 25%-450%). Thus, most of our commercial customers, making products such as computers, telecommunications systems, medical systems, and power supplies, choose to use the handbook for their reliability predictions. While MIL-HDBK-217 is used by both military and commercial companies, it is targeted for military applications, which might explain the somewhat pessimistic numbers it sometimes gives for commercial quality products. For example, you will probably have to use if you have military contracts or customers, or commercial contracts or customers that specify 217 for reliability predictions.
