Even though research teams in other countries are also attempting to develop a foolproof, lawsuit-proof test, the efforts based in France at the Laboratoire de Chatenay-Malabry and at the Australian Institute of Sport in Canberra may be by far the most advanced.

After the proof test and if successful, two or three proof marks are always applied to the main ( highly stressed ) parts of the arm, namely the barrel, the chamber ( when not part of the barrel ) and the locking mechanism.

The manufacturer's mark, along with the proof marks, and the weight of the barrels in grams, and the proof test pressures are also stamped alongside the choke marking on the tang of the barrels, near where the shells are inserted into the barrels.

Firearms sold in most countries are required to pass certain safety tests, particularly a proof test consisting of firing a special high pressure round ( proof load ) which far exceeds the European SAAMI pressure maximum for the round ( see internal ballistics ).

Under C . I . P . proof test standards a drilled case is used and the piezo measuring device ( transducer ) will be positioned at a distance of from the breech face when the length of the cartridge case permits that, including limits.

"You fly around a couple of years with the plane in service, carrying passengers, as a proof test that the combination of airplane and engine is a reliable combination and it's not going to keep flaking out, " said Richard S . Meyer, a FAA spokesman.

Under C . I . P . proof test standards a drilled case is used and the piezo measuring device ( transducer ) will be positioned at a distance of 25 mm from the breech face when the length of the cartridge case permits that, including limits.

She remained in storage through June 21, 1950, when her designation was changed from B-17G to DB-17G . She then went on to serve from 1950 through 1956 with the 3200th and 3205th Drone Group and Proof Test Wing at Elgin AFB, Holloman AFB and Eniwetok Atoll.

Development began in 1987 and developmental testing of the warhead ended in 1991, but French president Jacques Chirac asserted in June 1995 ( 50 years after the Atomic bombings of Hiroshima and Nagasaki ) that a full yield proof test was needed prior to deployment, causing an international outcry.
