MIL-DTL-5516D
4.4.2.2 Tests. The tests shall consist of those tests specified under "Test Methods" (4.5) for the
following properties:
(a)
Hardness
(4.5.1.1)
(b)
Specific gravity
(4.5.1.4)
* (c)
Tensile strength
(4.5.1.2)
* (d)
Ultimate elongation
(4.5.1.2)
* (e)
Modulus @ 100% elongation
(4.5.1.2)
* (To be used for monitoring only since values for dumbells were not established at first article --
not cause for rejection in this case. Values shall be recorded as part of the inspection records.)
4.4.2.3 Rejection and retest. Failure of any of the test specimens to conform to the acceptance
requirements of this specification shall be cause for rejection of the batch represented. A batch
that has been rejected may be reworked to correct the deficiencies and re-submitted for
acceptance.
4.4.3 Finished product tests. Tests shall be performed on unaged specimens from each day's
production of the specific sizes for which physical property values were established at first article.
These specimens shall be provided by the manufacturer, molded concurrently with other
production parts. Variation in physical properties shall not exceed those specified in Table II and
those contained in the First Article Approval Report.
4.4.3.1 Test specimens. For Class A material, one platen sheet (.075 inch (1.905mm) x at least
4.75 inch (120.65mm) x 4.75 inch (120.65mm)) shall be molded concurrently with other
production parts using the same production techniques.
4.4.3.2 Tests. The tests shall consist of those tests specified under "Test Methods" (4.5) for the
following properties:
(a)
Specific gravity
(b)
Tensile strength
(c)
Ultimate elongation
(d)
Modulus @ 100% elongation
4.4.3.3 Rejection and retest. Failure of any of the test specimens to conform to the acceptance
requirements of this specification shall require a retesting of an additional set of test specimens.
In the event of failure of any specimens in the retest, the finished products represented by the
specimens shall be withheld from acceptance until the extent and cause of failure has been
determined and correction verified by additional tests.
4.4.4 Process monitoring test. Tests shall be performed at six month intervals on unaged
specimens of the specific sizes for which physical property values were established at first article.
These specimens shall be provided by the manufacturer, molded concurrently with other
production parts.
4.4.4.1 Test specimens. For Class A material, eight AN6225-20 V-rings and two .075 inch
(1.905mm) thick dumbbells shall be selected at random from production or shall be molded
concurrently with other production parts using the same production techniques.
