If the specification for the ammunition item into which the detonators are loaded does not require that the check test be performed, the contracting

18、officer should insert a provision for the performance of the check test in that contract. The contracting officer will arrange for the contractor to be reimbursed for expenses incurred in the performance of the check test for possible deterioration. Two hundred (200) detonators shall be selected fro

Measure resistance between electrodes, using a current limited to one milliampere. The resistance shall

20、be no less than 2.5 ohms nor more than 4.0 ohms. If any detonator fails to meet the requirement, it shall be classed defective. If four or more defectives occur, the lot shall be rejected. b. The detonators that are not classed defective in step a. shall be functioned as specified in 4.5.8.1 and mee
