Testing is
33、 described in the First Article and Quality Conformance Inspection tables. 4.5 Methods of inspection. 4.5.1 Proving qround. These tests shall be performed at a Government proving ground in accordance with the applicable acceptance test procedure. The sample projectiles selected shall be fired in a M
34、185 or M199 Series cannon using a M119A1, Zone 8 charge. Chamber pressures will be based on copper pressure gages. I The projectiles and propellin charges shall be uniformly temperature conditioned to 21a Celsius (70oF) plus or minus lo Celsius (2oF) for a minimum of 24 hours prior to testing. Press
35、ure-time traces and differential pressures shall be obtained for information only by means of a spindle tap in the breech of the cannon and a piezo gage at the projectile base location for each projectile fired. Adequate photographic and instrumental coverage shall be provided to assure compliance w
36、ith requirements. Range and deflections shall be recorded for informational purposes only. In the event of any abnormal condition, as observed by personnel or instrumentation, an attempt shall be made to recover and examine the metal parts for informational purposes. An observer shall be stationed 4
37、000 + 200 meters from the edge of the impact area to record presence-of smoke signature. level terrain and the wind velocity shall not exceed 15 knots at the time of testing. The test shall be conducted on 5. PACKAGING 5.1 Packing and marking. The projectile shall be packed in accordance with Dwg. 9
