How Product Launches Are Won or Lost Long Before the Deadline
There comes a moment (typically far too late in the process) when someone in product development asks, “We can get this certified by launch… right?”
The room gets quiet.
Engineering looks at Quality. Quality looks at Regulatory (and in small businesses around the world, each of those teams amounts to just one person). Regulatory starts calculating how many pages are in the standard and how many nights of sleep remain before the ship date.
That moment is often when market success is decided, and when compliance is treated as a design input instead of a postscript.
I’ve said it at ISPCE Conferences over the years, various other IEEE conferences, in webinars, and in conference rooms all over the globe. Start working on product safety, compliance, and certifications as early in the development process as possible. Know, read, live, and breathe the standard before submitting your product to a certification body.
The products that thrive globally are usually the ones that have been designed and built with safety and certification threaded through the game plan from day one. The rest become cautionary tales shared at regulators’ dinner parties.
On a cheerier note, most product safety, certifications, and compliance issues are predictable and preventable. Whether you’re designing a consumer appliance, industrial control, or medical device, there’s a core set of requirements that apply across the board. Understanding these fundamentals from stage one allows you to build products that are inherently safer and easier to certify, which allows a faster and more efficient way to gain market access.
The Quiet Force Behind Market Access
So why do we care?
Compliance carries legal weight in many jurisdictions and commercial weight in all of them. Retailers require marks before products reach shelves. Business-to-business (B2B) procurement teams insist that new products hold recognized certifications. Inspectors look for labels before energizing equipment. Often, market access is dependent upon it.
And when you’re concerned about budgets and timelines, they are far more forgiving when safety requirements are addressed early. Retrofitting spacing into a crowded enclosure is rarely graceful. Replacing a non-compliant polymer after tooling is cut tends to produce colorful language. And the list of non-compliances that double as a one-way ticket to the island of forgotten projects is endless.
Beyond cost and scheduling, early compliance awareness sharpens engineering judgment. When a designer understands creepage and clearance distances, grounding integrity, flame ratings, and single-fault conditions, design decisions change. In this way, compliance comes with the gift of foresight. Reading and knowing the standards applicable to your product is critical to your certification project’s success.
A System Built on Hard Lessons
The modern certification ecosystem, while mysterious to the uninitiated, grew from pretty practical concerns: fires, shocks, boilers that exploded seemingly without warning.
When considering how we got here, all roads lead back to Underwriters Laboratories (UL). Born in 1894, Underwriters Laboratories began by examining electrical fire risk in a rapidly electrifying America. Some might say the modern history of compliance can be distilled down to BUL versus AUL (before UL, after UL). It’s hard to overstate their influence on the system we still abide by to this day.
Around the same time, Edison Testing Laboratories (ETL, now associated with Intertek) was founded to evaluate the safety and performance of electrical equipment. And internationally, TÜV Rheinland traces its origins to 1872, when industrial boiler safety was not an academic concern but a daily hazard.
The mission was straightforward: reduce shock, fire, and personal injury. The complexity came later as product categories multiplied and global markets intertwined.
Today, having won our campaign to prove that safety matters, our efforts are more focused on navigating an increasingly abundant web of standards, national deviations, and approval pathways. As the pulse of innovation quickens, so too does the need for compliance experts equipped for the demands of thismoment. In other words, don’t blink.
The United States: NRTLs and Practical Reality
The approach to safety in the United States (U.S.) takes American individualism to its logical conclusion. We are different from almost any other market in that federal law does not universally mandate third-party certification before sale. In other words, it’s buyer beware until the product is plugged in. Then the real fun begins.
Workplace regulations and electrical codes create powerful requirements once equipment is installed or used. The U.S. Occupational Safety and Health Administration (OSHA) maintains the Nationally Recognized Testing Laboratory (NRTL) program. More than 20 NRTLs are authorized to certify products within defined scopes. The menu is extensive, provided you’re ordering from the right section.
Marks from NRTLs carry legal equivalence within their approved categories. The operative phrase here is “within their approved categories.” It’s a phrase narrow enough to skim past, yet weighty enough to derail a launch. OSHA authorizes each laboratory for specific standards, and not every NRTL covers every product type.
Verifying the NRTL scope before engaging a testing laboratory avoids nasty surprises at precisely the wrong moment in a project timeline.
Canada: Certification at the Border
Our cousins across the way have quite a different outlook on pre-market compliance. Products generally require certification to enter the market. Accreditation is overseen by the Standards Council of Canada, and many major U.S. NRTLs maintain Canadian recognition as well.
Products without the appropriate mark may find their journey paused at customs.
Europe: CE Marking and Direct Accountability
CE markingis mandatory for products placed on the market in the European Economic Area. Unlike the North American reliance on third-party marks, many CE directives permit manufacturer self-declaration. Think of it as the loftiest pinky swear you’ll ever make.
The CE framework offers autonomy. It also assigns responsibility without mediation. Manufacturers must identify applicable directives, often covering electrical safety, electromagnetic compatibility, machinery, radio equipment, hazardous substances, and waste obligations. Then, they select harmonized standards, test accordingly, and maintain documentation supporting compliance.
When authorities ask questions, your Technical File should be the source of youranswers. Technical files should always include design drawings, schematics, risk assessments, calculations, test reports, instructions, and the Declaration of Conformity. Regulators have elephant-like memories. Documentation must typically be retained for ten years after the last unit is manufactured. Make sure you have it at the ready because market surveillance authorities can request it with limited notice.
Manufacturers based outside the EU must also appoint an Authorized Representative. That representative assumes defined legal responsibilities. Choose accordingly. Selecting one with genuine technical and regulatory expertise is critical.
Enforcement activity across Europe includes product withdrawals, border actions, fines, and, in serious cases, criminal proceedings. CE marking rewards diligence and punishes casual assumptions.
Global Expansion: Strategy Before Testing
When venturing beyond North America and Europe, be ready for anything. Some countries mandate in-country testing. Others maintain compulsory certification lists. Acceptance of international test reports varies.
CB reports and ILAC-accredited data travel well, but they’re far from untouchable. National deviations still demand attention. Effective global planning begins with identifying target markets early and building a compliance roadmap aligned with commercial strategy. Lock in your target markets as early as possible. If your compliance roadmap is inextricably linked with your commercial strategy, you’ll avoid plenty of heartache overseas.
Adding a radio? Add some regulators. Wireless functionality introduces additional layers of certification in nearly every jurisdiction. Tune your budgets and schedules to a frequency that accounts for this reality.
When it comes to product-specific requirements, the complete collection of traps and pitfalls is too exhaustive to list here (though I plan to cover at length in the next iteration of this piece). However, I’ll take you through some non-compliances that stick out in my mind from my nearly 40 years navigating these murky waters.
Common Pitfalls That Stop Production Lines
When regulatory compliance is positioned as an afterthought, production lines get red-flagged. Products sit idly in lonely warehouses. Launch dates slip. Costs balloon. Here are the most chronic offenses:
- Assuming that component marks equal product approval:Your bill of materials might list all NRTL-Recognized components, but that doesn’t make your product NRTL certified. Each component’s Conditions of Acceptability must be satisfied in your specific application.
- Ignoring material specifications:Engineers swap materials for cost or availability without checking flame ratings, temperature ratings, or electrical properties. That plastic enclosure that was V-2 rated in white might not maintain that rating in black. That change from 3mm to 2mm thickness? You may have just invalidated your flame test results.
- Inadequate spacing:Creepage and clearance requirements exist for good reasons. Tight PCB layouts that ignore these requirements fail dielectric testing. No amount of arguing will change the physics.
- Poor strain relief:Cord entry that looks adequate in the CAD model fails the 35-pound pull test. Bushings that aren’t real strain relief. Clamps on insulation only that still allow wire movement inside. These are easy to get right if you know the requirements before designing the part.
- Missing documentation:For CE marking, your Technical File is not optional. Neither is your Declaration of Conformity. You can’t slap a CE mark on products and hope nobody asks questions. Regulators do ask, and “we didn’t know” is not an acceptable answer.
- Late-stage discovery of jurisdiction-specific requirements:You designed for North America, then discovered the European version needs fuses in both line and neutral. Or that the cord colors are different. Or that the hard-wired product needs different terminal markings. These are all predictable and preventable… if you read the standard and plan ahead.
How to Think About Compliance Early
Engineers who succeed with compliance build it into their design process from day one. Here are some recommended steps:
- Start by reading the standard:(If there’s one takeaway from this article, I hope it’s this piece of advice). Yes, the whole thing. Learn its contours like a magnificent piece of sculpture. It’s your Holy Grail. Standards contain everything you need to know when the path becomes unclear. Understand what will be tested and why it changes your design choices.
- Identify target markets and applicable standards during the concept phase: Don’t wait for a working prototype. Different standards have different requirements affecting fundamental decisions like enclosure materials, cord types, and component selection.
- Use existing resources:UL.com has extensive databases for material ratings, wiring, and component listings. These tell you exactly what’s been previously tested and approved.
- Network with professionals:Certification body engineers are met with a conflict of interest when it comes to helping you get into compliance mid-project. Build your network and lean on other product safety engineers who have solved similar problems. That’s also why resources like the IEEE Product Safety Engineering Society (PSES) exist: to spread this knowledge.
- Design for testability: Make sure you understand each and every test coming your way, in detail. Eyes shouldn’t go wide when I tell engineers we’re going to hit your product with a steel ball from 3 feet at the thinnest area of your enclosure.
- Keep compliance engineers in the loop:Include them in design reviews. Asking questions while making changes is still easy. Moving a component on PCB before layout? Zero cost. Respinning boards after build? Pricey and time consuming.
- Plan for variations:If you’re designing a product family, think about compliance across all models. Sometimes, testing the worst-case scenario covers multiple models with a single certification. Sometimes each variant needs individual evaluation. Understanding this early prevents costly surprises when your product line expands.
The Real Benefit: Better Products
Understanding compliance requirements isn’t like school. It doesn’t make you better at passing tests. It makes you better at engineering.
When you know why clearances are required, you understand electrical breakdown. When you grasp why specific materials are needed, you understand material properties and failure modes. When you see why thermal protection is specified at certain temperatures, you understand heat transfer and component degradation.
Products designed with these principles from the start are safer, more reliable, and less likely to fail in the field. They cost less because you’re not discovering problems during pilot runs. They reach market faster because you’re not iterating through multiple test cycles.
The more you understand the “why,” the safer everything you build becomes.
Be safe!
