The “Working Load Limit” (rated capacity) is the maximum load that shall be applied in direct tension
to a new and undamaged straight length of chain.

The “Minimum Breaking Force” is the minimum force at which the chain during manufacture has been found by testing to break when a constantly increasing force is applied in direct tension. Breaking force values are not guarantees that all chain segments will endure these loads. This test is a manufacturer’s attribute acceptance test and shall not be used as a criterion for service or design purposes.

Any static or dynamic load in excess of “Working Load Limit.”

The selection of the base material is left to the judgment of the individual chain manufacturer provided that the resultant chain complies with the requirements contained in this specification.

The manufacturer will select suitable manufacturing methods such that the chain complies with the requirements contained within this specification.

A test specimen shall consist of a length not less than one foot (0.3 meter), taken from any stage of manufacture after the forming process.

Fixtures for securing chain test specimens in the testing machine must securely support the link. Links engaged in the testing fixtures shall not be considered part of the test
specimen.

The actual dimensions may vary by ±7%. The inside length dimension can be measured either by individual link or by measuring the span of 100 links and dividing by 100.

The manufacturer may apply a surface treatment or coating of his or the customer’s choice for identification or corrosion resistance unless the customer specifies otherwise.
