 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.This publication is reviewed frequently to ensure that the standards published remain of an acceptable standard in light of potential changes to the industry or technology that may occur.The IPC/WHMA-A-620 publication has standards for a wide range of elements within a cable harness, including but not limited to electrostatic discharge protection, conduit, installation and repairs, crimping, pull-test requirements, and other operations that are critical to the production and function of cable harnesses.
