6.3 Definitions.
6.3.1 Breaking load. Minimum force in pounds at which the chain, during manufacture, has been found by testing to break when a constantly increasing force is applied in direct tension. This test is a manufacturer's attribute acceptance test and shall not be used as criteria for service or design purposes.
6.3.2 Proof load. Quality control tensile test applied to chain for the purpose of verifying weld and material quality. It is the minimum force in pounds which the chain has withstood at the time it left the producer, under a test in which a constantly increasing force has been applied in direct tension to a straight length of chain. Proof loads are a manufacturing integrity test and shall not be used as criteria for service or design purposes.
6.3.3 Working load limit. Maximum combined static and dynamic load in pounds that shall be applied in direct tension to an undamaged straight length of chain.
