IPC WHMA-A-620

Wire Harness & Cable Assembly Standard

WH Kemp’s operators are trained to the latest IPC/WHMA-A-620 standard. This prescribes the practices and requirements for the manufacture of wiring harnesses and cable assemblies. The standard covers the methods, tests and acceptability criteria for crimped, mechanically secured and soldered interconnections. 

Additionally, it covers the related assembly activities involved in production such as cable ties, measurement, and appearance.

UL Recognized Component

WH Kemp’s cable assemblies and wiring harnesses have held UL Recognition since 1986, under file ZPFW2.E101874. UL Assessors come onto site unannounced to conduct quarterly inspections; all reports show compliance with follow-up services. UL Recognized Component status applies to specific components and constructions assessed and authorised by UL for use in a larger, UL-Listed end products. Where a customer’s product requires UL-recognised wiring harness components, we build to that recognition; where it doesn’t, we don’t reference UL in connection with it. If your project has UL requirements for the US or Canadian market, our team can confirm scope and current file status against your specification.

What These Accreditations Mean

Compliance

Maintaining high standardsAt WH Kemp, compliance is not simply about meeting standards, it is about doing business the right way. We maintain robust management systems that ensure we meet our legal, regulatory and customer obligations across quality, environmental management and health & safety.

Alongside our accredited management systems, we operate policies covering areas such as Modern Slavery, Anti-Bribery and Corruption, Conflict Minerals, REACH, RoHS, Cyber Security and Data Protection. We regularly review our procedures, train our people and ensure compliance is maintained as regulations and expectations evolve.

Responsible Manufacturing

At WH Kemp, we believe responsible manufacturing is about doing the right thing for our customers, our employees and the environment. That means continually reducing waste and improving environmental performance, and providing a safe workplace where people are respected, supported and able to take pride in their work. Fairness and respect aren’t just words in a policy, they’re the reason so many of our people choose to build their careers with us. Nine members of our team have been with WH Kemp for more than twenty years, contributing to over 450 years of combined experience on our factory floor.

We believe the way a company behaves matters just as much as the products it manufactures. That’s why we strive to run our business openly, honestly and with integrity, treating customers, colleagues and suppliers fairly, taking responsibility when things go wrong, and doing what we say we will do. We believe that’s how trust is earned, and how long-term relationships are built.
