36、upply inspection equipment compatible with the “Test Methods and Procedures“ specified in 4.6 of this specification and with the component inspection procedures specified in “Examination I and “Test Facilities“ requirements of MIL-F-13926. Since tolerance of test equipment is normally considered to

37、be within 10% of the product tolerance for which it is intended, this inherent error in the test equipment design must be considered as part of the prescribed product tolerance limit. Thus, concept, construction, materials, dimensions and tolerances used in the design of test equipment shall be so s

38、elected and controlled as to insure that the test equipment will reliably indicate acceptability of a product which does not exceed 90% of the prescribed tolerance limit and permit positive rejection when nonconforming.

42、ected to the tests of 4.6.4, 4.6.5, 4.7.1, 4.7.2 and 4.7.3 to determine compliance with 3.4.2. 4.6.3 Rain test.- The rain test shall be conducted in accordance with Procedure I of MIL-F-13926 and the conditions of 3.5.1. Subsequent to the rain test the case shall be subjected to a visual and tactile

43、 examination to determine compliance with 3.5.1. 4.6.4 Flexural resistance test.- This test shall be conducted utilizing a 2 inch diameter mandrel for the M63A1 Case and 1 1/2 inch mandrel for the M62A1 Case. With the mandrel inserted into one side (monocular simulation) of the respective case, a su

44、fficient force shall be applied to the open (empty) side over a minimum area of one (1) square inch until at least half the circumference of the mandrel is in contact with the inner wall of the case cavity.
