Industrial Standards For Wiring Harnesses

Oil and gas the environments faced by the energy industry are some of the most demanding. Necessary to ensure full compliance of wire assemblies to this standard. Insulation chosen for the aircraft wire harness design engineer select wire part number to use.

The industry standard for wire harness manufacturers is the ipc 620 certification.

Industrial standards for wiring harnesses. Industry quality standard although customer specifications take the highest priority when creating cable harnesses of a certain quality in north america if no such specifications are found the quality standards of a cable harness are standardized by the ipc s publication ipc whma a 620 for minimal requirements for cable harnesses. They are recognized in the cable and wire harness industry through their understanding of the value of the ipc whma a 620 certification the worldwide benchmark for quality workmanship. Connectors shall be straight right angle or flange mount. There is ample documentation to substantiate this claim.

The wire harness manufacturer s association and the ipc association connecting electronics industries combined forces to create the ipc whma a 620c requirements and acceptance for cable and wire harness assemblies which is an amazing resource for wire harness manufacturers. In addition connector disconnects will determine when a wire goes through a bulkhead. Using a 3d cad system the wire paths are specified throughout the aircraft. An ipc certified wire harness manufacturer trains people in accordance to these standards and have process controls in place to monitor.

Cable and harness general requirements cont preferred. Let s face it folks no automobile manufacturer ever designed a wiring harness to last 40 70 years. Our wiring harnesses are brand new and better than n o s. The ipc whma a 620 standard revision c remains the only industry consensus standard for requirements and acceptance of cable and wire harness assemblies.

Wires are stranded conductors ranging in size from 0 35 mm2to 6 0 mm2 or approximately 22 to 9 gage awg that make up most of a vehicle s wiring harness. These manufacturers stay ahead of the competition by networking with leading manufacturers and suppliers and staying up to date on industry best practices and reports. The ipc whma a 620c serves as the only industry consensus international wire harness assembly standard for the performance and acceptance of cable and wire harness assemblies. Smaller sizes save cost and weight.

Each wire in a wire segment is then uniquely identified see chapter 4 wire. New old stock the problem. The larger sizes accommodate higher current loads with less resistance. We develop wire harnesses that take advantage of all these options as well as custom vehicle harnesses that incorporate new energy technologies including gas pump wire harnesses.

Ipc and the wiring harness manufacturer s association whma continue to work together to develop this significant update. Soldering stripping crimping securing etc. The use of right angle connectors shall be minimized and restricted to applications where stress free mounting of the cable assembly can be assured. As a matter of fact your vehicle s original wiring was only designed to last 10 years before it started to deteriorate.
