The scope of this standard is the development of a common receiver fixture interface (RFI) specification that is based upon available commercial standards integrated under a common open architecture. This mechanical/electrical interface is intended to serve government/commercial interest for applications in test, system integration, manufacturing, monitoring, and other functional requirements that demand large contact densities and quick-disconnect mechanical operation.dition 1.0 2015-12 ？ IEEE Std 1505 INTERNATIONAL STANDARD colour inside Standard for receiver fixture interface IEC 63004:2015-12(en) IEEE Std 1505-2010 THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2010 IEEE All rights reserved.
