3.7 Physical requirements.
3.7.1 Breaking load. The breaking load of the finished cable shall be not less than the value
specified on the applicable specification sheet (see 3.1), when tested as specified in 4.6.3.1.
3.7.1.1 Staycord breaking load (see 3.3.2.3). The breaking load of staycords shall be not less then
40 pounds (18.14 kg), when tested as specified in 4.6.3.1. The diameter shall be approximately the same
as that of the insulated tinsel wire conductors in the cord. The staycords shall not abrade or otherwise
damage the insulation when the cord is bent or stretched.
3.7.2 Cold bend. The insulation of braided cable, consisting of the wire insulation and jacket of
jacketed cable, shall not exhibit any evidence of cracks, flaws, or other damage when tested as specified
in 4.6.3.2.
3.7.3 Sea-water resistance. When specified on the applicable specification sheet (see 3.1), the
finished cord shall be tested for sea-water resistance as specified in 4.6.3.3. The weight change of the
cord shall be not more than 5 milligrams per square inch (25.4 square mm) of wetted surface, and there
shall be no evidence of chemical reaction or other deleterious effects to the jacket when visually
examined.
3.8 Workmanship. The tinsel wire used in manufacturing the cable shall not have any broken
strands. The cable shall not have any missing tinsel wire. The wire insulation and cable jacket shall not
have nicks, rips, cuts, peeled surfaces, and any imperfections that can affect performance. The insulation
and jacket shall be uniform in shape and free of kinks. The jacket shall be properly centered over the
tinsel wire.
