MIL-DTL-83538 Connectors And Accessories, Electrical, Circular, Umbilical, Environment Resistant, Removable Crimp Contacts For Mil-Std-1760 Applications \(Metric\), General Specification ForThis specification covers connectors and accessories, electrical, circular, umbilical. The connector assembly provides the necessary connections required to meet MIL-STD-1760, class I electrical interface between stores and their associated launchers using a "blind mating" mechanism. The connector assembly consists of a receptacle installed on the launcher, a receptacle installed on the store, and a buffer plug installed between the two receptacles. This specification also includes the required mounting adapters and nut, accessory adapter, cable bushing, and protective covers \(see 6.1 for details on intended use and application\). The connectors covered by this specification are intended for use with launcher mechanisms with an applied holding force in the range 271 Newtons \(61 lbs\) to 427 Newton \(96 lbs\).

4.5.1.2.2 Lot definition (Group B inspection). The production lot definition as specified in MIL-STD-790

is further defined as follows:

a. A production lot consists of all connectors covered under one military specification or standard,

manufactured from the specified raw materials, processed under the same specification and

procedures, produced by the same type of equipment, and submitted for inspection at one time.

Each production lot of assembled connectors shall be a group identified by a common

manufacturing record through all significant assembly operations.

b. Traceability of connectors to specific physical/chemical test reports of incoming raw material is not

required.

c. Common manufacturing records and traceability shall begin with the start of connector assembly.

4.5.1.2.3 Disposition of sample units. Sample units which have passed all of group B inspections may

be delivered on the contract or purchase order if the lot is accepted and the sample units are still within

specified tolerances.

4.5.2 Periodic inspection. Periodic inspection shall consist of group C inspection. Except where the

results of this inspection show noncompliance with the applicable requirements (see 4.5.2.1.4), delivery

of products which have passed groups A and B inspections shall not be delayed pending the results of

this periodic inspections.

4.5.2.1 Group C inspection. Periodic tests for group C inspections shall be performed on a 12-month

and 24-month basis, beginning with the 12-month periodic test, which must be accomplished within this

period after notification of qualification and alternating thereafter with the 24-month periodic test.

Samples submitted to either of these periodic tests shall have passed groups A and B inspections.
