Design and construction: See figures 1 through 22. Corrosion (salt spray): Method 101, test condition B, in accordance with MIL-STD-202. The salt solution concentration shall be 5 percent. Special detail: After exposure, hardware shall be washed, shaken and lightly brushed as specified in method 101 of MIL-STD-202, and then permitted to dry for 24 hours at 40C. Hardware shall then be examined for evidence of corrosion and pitting and ease of coupling. Marking: Marking shall be in accordance with MIL-PRF-39012 except that the marking location may be on the wire rope jacket or on a shrink tubing on the wire rope. Qualification by similarity: Connectors manufacturers may qualify all applicable PIN's for dust caps by similarity if they submit any representative sample of a bead chain, safety chain, and wire rope with applicable qualification testing. A manufacturer must be qualified to that connector series using that same material in order to be approved by similarity. Cross reference data: See tables I and II. 36 MIL-PRF-39012/25F TABLE I.
