1 DEFINITIONS
link: a one-piece steel link consisting of end bar A, hook B, and two sidebars C-C (see Fig. 2 of B29.6).
measuring load: the load under which a dry or lightly lubricated chain should be measured for length.
steel detachable link chain: a series of successively assembled steel links in which the end bars articulate inside the hook. The chain is detached by flexing it and driving the end bar out of the adjoining hook (see Fig. 1 of
B29.6).

3 GENERAL CHAIN PROPORTIONS AND DESIGNATIONS
3.1 Minimum Ultimate Tensile Strength
The Minimum Ultimate Tensile Strength (M.U.T.S.) for chain covered by this Standard is the minimum force at which an unused, undamaged chain could fail when subjected to a single tensile loading test.
WARN ING: The Minimum Ultimate Tensile Strength is NOT a “working load.” The M.U.T.S. greatly exceeds the maximum force that may be safely applied to the chain.
(a) Test Procedure. A tensile force is slowly applied, in a uniaxial direction, to the ends of the chain sample.
(b) The tensile test is a destructive test. Even though the chain may not visibly fail when subjected to the M.U.T.S., it will have been damaged and will be unfit for service.
CAUTION: This load is beyond the yield strength of the chain and would render the chain unsuitable for application.
(c) For application guidance, consult the manufacturers’ catalogs or the American Chain Association’s handbook, Chains for Power Transmission and Material 1—landling.
