Are field inspections really that mysterious?
Are field inspections really that mysterious?
Not quite, but they do come with a lot of myths, a few nerves, and occasionally… a juice bottle pretending to be an electrical enclosure (we’ll get to that).
At LabTest Certification, we’ve performed countless field evaluations across North America and worldwide, from clean rooms to construction sites. And while the what of a field inspection is serious, the how doesn’t have to be intimidating.
In this article, we’re clearing up the confusion. You’ll learn:
- What field inspections actually involve
- What our inspectors are looking for
- Common myths we hear (and why they’re wrong)
- Some of the strangest things we’ve seen on the job
What Is a Field Evaluation?
A field evaluation (also known as a field inspection or Special Inspection) is a one-time, on-site assessment of a product or equipment that doesn’t already bear a recognized certification mark (like the LC Mark). It’s often required for:
- Custom-built or one-of-a-kind equipment
- Modified or relocated machinery
- Imported equipment lacking North American or other international approvals
- Prototypes or pre-certified products
The goal? To verify that the product complies with applicable safety standards/model codes (such as SPE-1000 for Canadian market, NFPA 791 for U.S. market, or any other CSA, UL, IEC, EN, and more, standards) and won’t pose a risk to people, property, or your facility’s electrical system.
What Do We Actually Look At?
Our field evaluation process includes a combination of visual inspection, documentation review, and sometimes on-site testing. Depending on the type of product and its application, here’s a quick peek at what our inspectors typically evaluate:
- Grounding, bonding, and protection against shock
- Overcurrent protection (fuses, breakers)
- Component and wire ratings
Proper installation and wiring methods - Enclosure types and locations (e.g., NEMA ratings)
Safety interlocks (if required) - Markings, nameplates, and warning labels
- User manuals or installation instructions (when applicable)
After the evaluation, if the product complies, we apply our LabTest Field Evaluation label and provide you with the supporting documentation (e.g., technical reports).

Top 3 Myths About Field Inspections
1. “Field inspectors want to fail me.”
Actually, we don’t. Our goal is to help you meet compliance requirements, not stop your project. We’ll clearly explain any issues found and, whenever possible, offer guidance on how to fix them.
2. “We’ll have to shut down our whole operation.”
Most field evaluations are non-disruptive. As long as we can safely access the equipment and someone is available to answer questions, we can usually work around your schedule.
3. “It’s just a formality.”
Not quite. A proper field evaluation follows specific inspection criteria and applicable standards. It’s not a rubber stamp, and that’s a good thing. Cutting corners could cost you time, liability, or worse.
Real-Life Weirdness: The Fun Side of Field Inspections
You didn’t think we’d skip this part, did you?
Here are a few of the more “unusual” things our inspectors have come across in the field:
The Juice Bottle Enclosure
An energized power input was mounted inside a repurposed juice bottle. Reuse is great, but not for electrical containment.
The DIY Nameplate
A required label was added using a Sharpie marker. Creative, yes. Compliant? Not even close.
These examples may raise a smile, but they also highlight why field evaluations matter. Equipment that hasn’t been properly inspected could pose serious safety risks.
Should You Be Nervous About a Field Inspection?
Not at all. Field evaluations are collaborative, informative, and—dare we say it—surprisingly painless when you’re prepared.
