IPC/WHMA-A-620

Targeting Excellence in Cable and Wire Harness Manufacturing

IPC/WHMA-A-620, Requirements and Acceptance for Cable and Wire Harness Assemblies, now at Revision C published January 2017, is the industry consensus standard for cable and wire harness fabrication and installation. Theoretical training is provided and classes of products are defined and include criteria for Target, Acceptable, Process Indicator and Defect conditions to support the collection of visual quality acceptability requirements for each class. These criteria are supported by full-colour illustrations.

Revision C, developed by task group members from user and supplier companies, represents a consensus among industry leaders. The IPC Wire Harness Acceptability Task Group of the Product Assurance Committee and the Wire Harness Manufacturers’ Association Industry Technical Guidelines Committee prepared this standard.

IPC/WHMA-A-620 describes acceptability criteria for crimped, mechanically secured, and soldered interconnection and the corresponding lacing/restraining criteria associated with cable and harness assemblies.

An industry developed and approved program that includes training, certification, and instructional materials based on the IPC/WHMA-A-620C is available to your company.
