[time-nuts] Question for the cesium nuts.

Hi Again Hal,
There are standards for de-militarisation, you used to be able to
download manuals on it from the LOGSA web site but they seem to have
closed up that information source :-( I remember a couple of examples,
when they sold Jeeps in the UK for scrap you had to either cut them
diagonally corner to corner through all major components or crush them
completely with a tracked vehicle before they left the site. 
Apparently the local tracked vehicle drivers were usually happy to
oblige. For aircraft the standard was to cut through the fuselage in two
places or through each main wing spar. Allegedly the reason there are so
many F86 Sabre's still flying is that one disposal site cut only the
wings and another cut only the fuselage!

That's an interesting corner of the world that I've never worked with.

Is there an official test spec for destroying gear?  :(
Something like how big a bulldozer you have to crush it with.

Google finds references to a barge test, and things like this:
