Rich,
As long as sufficient cooling time, i.e. 1 minute, is allowed between
first level surges, whether they be similar or not, the equipment
should perform normally. I interpret that without replacing parts.
If you were referring to the second level surges , only then would I
agree with the component manufacturer.
A good contact to ask at Bellcore is Jim Brunssen.

Hello Treggers,
I have been told by one of our parts vendors that it is acceptable to =
replace components between the different surge waveforms when doing =
testing to sec.4 table 4-2 for first level lightning surges. Their =
rationale is that the components are being stressed by the previous =
tests. I am not convinced. I thought that each test sample should =
withstand all of the surges. I don't want to take the vendor's word =
alone because it is their parts that are failing.
Any similar experiences or comments would be appreciated.
