they are lifed to 10,000 hours or 30.000 launches whichever is sooner.

it used to be 6000 hours but the extension from brasov took it to 10K.
why it the states is it lifed on its age, seems an awful waste??

IIRC, the same 10000hr/30000launch extension included a 20 year
service life, or at least did not alter it. That was done later under
life extension inspections. I looked at a low time IS28B2 in the UK
and did not buy it at the time due to the then unresolved 'shelf
life'. That was in 1995. BGA rules at that time regarding such
things are somewhat different than US FAA rules. Those vary from
country to country. A classic example is the L-13, which is 'lifed'
by hours in many countries, but not in the US. In Australia, some
IS28B2's have far exceeded 10,000 hours.
