MIL-STD-1130 Connections, Electrical, Solderless WrappedThis standard establishes the requirements to produce mechanically and electrically stable, solderless wrapped, electrical connections made with single, solid, round wire and appropriately designed wrapposts terminals.This standard includes:a. Classes and requirements for solderless wrapped connections. b. Description and requirements for the wire used in making the solderless wrapped connections. c. Description and requirements for the wrappost used in making the solderless wrapped connections.

MIL-STD-1130C

5.4  Wrapping tool condition.

5.4.1  Initial verification of process conditions.

5.4.1.1  Verification of acceptable tool condition.  The capability of the wrapping tools to provide acceptable solderless wrapped, electrical connection shall be established at a facility acceptable to the procuring activity for each combination of wrappost (based on cross sectional geometry), wire gauge, and wrapping bit and sleeve configuration by inspecting 24 sample connections to the following requirements:

Acceptance of the sample connections shall constitute initial verification of acceptable tool condition.

5.4.2  Reverification of tool conditions.

5.4.2.1  Reverification of process and conditions.  Following initial verification of tool condition, samples shall be inspected in accordance with the following requirements at the time intervals specified as follows:

Acceptance of sample connections shall constitute reverification of acceptable tool condition.

5.5  Rewrapping.

5.5.1  Rewrapping of wire.  It is not permissible to rewrap the portion of wire that has been previously wrapped on a wrappost.

5.5.2  Rewrapping of wrappost.  Wraps can be made on the same portion of a wrappost from which a previously made solderless wrapped connection has been unwrapped (pull-off or stripping is not allowed). The connections must be capable of meeting the requirements of this standard.
