How one decision became thirty years of continuity.
In OEM electronics, getting a product certified is the part you control. What you don’t control is everything after: the standard that gets revised, the component that goes end-of-life, the recertification nobody scheduled.
This distributor decided not to carry that part at all. For three decades, they have handed it to KELD.
Who owns certification for the life of the product?
KELD certified for the US market first — before there was a customer — because UL there is the entry condition, not a differentiator. Since the early 1990s, the client defines the need and the target market and receives a finished, certified product. Everything in between stays with KELD:
- Lifecycle management — standard changes and component obsolescence are detected and handled before they become the client’s problem.
- Obsolescence in practice — when a critical microcontroller reached end-of-life, KELD adapted the firmware, assessed the certification impact and told the client before the change reached them.
- Field response — over thirty years something eventually fails; KELD puts people and resources on it wherever support is needed.
It works because design and manufacturing sit under one roof — the same APQP discipline KELD applies across OEM programs, and the reason it can manage the UL lab and recertification cycles independently.
“We have never had to worry about what comes next: the standard changes, the obsolescence, the recertifications. KELD anticipates and resolves them, often before we notice. Over thirty years, that has a value you will not find on any datasheet.”
— Technical Director, global industrial-instrumentation distributor
Common questions
Is UL certification a one-time event or an ongoing responsibility?
Ongoing. Getting the file granted has an end date; keeping the product sellable does not. Standards are revised and components go obsolete, and both can require firmware changes and reopening the certification file.
What happens when a certified component goes obsolete?
The end-of-life part is replaced, the firmware often adapted, and the certification impact assessed — sometimes reopening the UL file. Whoever owns the design manages this; here KELD does, so the client carries no lifecycle burden.
Who talks to the UL lab — the OEM brand or the manufacturer?
Only the design owner can, because certification means disclosing confidential subsystem specifications to the lab. KELD is the single technical contact and keeps the client’s specifications protected.
