Whilst looking for something else, I've just stumbled across this list.

It's about "Expected Equipment Lifespans", and uses both GMDN and UMDNS codes. smile

Although I must say that it all looks a bit "random" to me! The table would have been so much more useful if it had included the Risk Factor (as mentioned in the premable) for each item, as well as the "formula" used to arrive at it.
