29、 sample acceptable for functional and environmental testing shall be defined as a sample which has met the applicable requirements of 3.2 through 3.4 of this specification. Sixty cartridges shall be expended in the tests listed in table I and three shall be retained for investigative purposes. The c
30、ontractor shall deliver the cartridges to the activity designated by the contracting agency for tests. Any damage inflicted by the environmental treatments, which would adversely affect the performance of the item in service application shall cause rejection of the first article sample. Any further
31、production prior to notification by the contracting agency of first article sample acceptability shall be at the contractors risk.
