Requirements Document for Evaluation of Environmentally Preferable Aircraft Electrical Connectors

摘要

This document describes the minimum requirements and desirable characteristics for an environmentally preferable electrical connector for use on U.S. Air Force aircraft. This report also describes a proposed test procedure that can be used to evaluate candidate connectors. Environmentally-preferable connectors should be made from materials less hazardous than those used in existing connectors, but that still possess adequate grounding and corrosion resistance. The hazardous materials of concern are the EPA-17 chemicals, including cadmium, chromium, and nickel, currently used in the manufacture of MIL-38999J Series I and II, finish B, and Series III and IV, Classes J and W, connectors. This document is divided into the following sections: 1. Section 1, Background, provides background information that defines the nature of the problem. 2. Section 2, Requirements, establishes the general requirements for an environmentally preferable connector. 3. Section 3, Test Layout, describes the order of the tests conducted on each connector. 4. Section 4, Rationale for Requirements and Characteristics, provides the rationale for the requirements that have been established in this document. 5. Section 5, Protocols, describes the procedures that will be used to evaluate candidate connectors. This document can be used as a basis for a formal test procedure.
