Notes:
All finished components shall be tested before the protective coating is applied to the steel. All test specimens shall
be free of any coating, and swept, sand blasted, or cleaned by some other specially approved means.
4.5 Preparation for inspection.
4.5.1 Specimens. Prior to inspection, all specimens shall be swept clean by sand blasting to
SSPC-SP-10 or equivalent means to allow proper examination and testing. Specimens are to be
taken, as specified in table IV, from finished components, that were heat treated, worked, and
reduced (where applicable) from the same size and type as the component represented.
4.6 Examination and tests.
4.6.1 Break test. A test specimen shall be taken from finished components as specified in table
IV. Specimens of chain shall be manufactured at the same time as the chain and attached so that
the three links will be heat treated with the shot of chain. The accessories test specimens shall be
selected at random from finished components in the required number from the same heat
treatment, size, and type. If there is no sign of fracture after application of the required load given
in 3.3.1 and table II, the specimen passed the test. If the chain specimen fails, one additional
specimen may be cut out of the same length of chain at a point adjacent to where the first
specimen was taken. If the second test fails, the represented shots shall be rejected. If the
accessories specimen fails, the 25 accessories shall be rejected. All components fitting a range of
sizes shall be loaded to the highest applicable nominal chain size load. The plate sinker shackle
with its bolts shall be tested separately from other components.
4.6.2 Proof test. All components shall withstand the applicable proof load given in 3.3.1 and
table II. For chain testing, if one link fails, the shot shall be rejected. All components fitting a
range of sizes shall be loaded to the highest applicable nominal chain size load. After proof-
loading, the length of chain shall be measured at a load of 10 percent of the specified proof-load
