The NRTL Certification Challenge: What You Need to Know

A growing challenge in the wood industry is dealing with machinery or equipment that lacks the mandatory NRTL (Nationally Recognized Testing Laboratory) or equivalent certification. While this may seem like an obstacle to buyers, it can be easily overcome with the right plan and resources.

At Lone Pine USA, most of the equipment we source does not come with NRTL or CSA certification. However, we provide resources for customers who purchase non-certified machines and need help passing safety inspections. Here’s how you can navigate this challenge and ensure your equipment complies with safety standards.

Understanding NRTL and CSA Certifications

Many machines that lack an NRTL or CSA certification still contain the necessary components for certification. To obtain this certification, they must undergo a field evaluation conducted by a licensed technician.

It's important to note that CSA certification (Canadian standards) does not replace the NRTL label. However, CSA ratings tend to be more stringent, and machines that meet CSA standards typically pass the evaluation process.

Preparing for a Field Evaluation

Before a field evaluation can be conducted, your machine needs to meet several conditions:

• Original factory build (not modified)
• Fully assembled, started up, programmed, and operational
• Electrical safe working condition with all manuals, nameplates, and electrical specifications ready for review.

The technician will also need your facility’s electrical information to proceed with the evaluation.

The Field Evaluation Process

After the evaluation, the technician will either apply the NRTL label or provide a correction plan outlining the necessary modifications for certification. If the machine has been modified, technicians can sometimes issue a field listing to a licensed engineer, allowing them to perform required corrections on-site.

The evaluation itself is a detailed process, where the technician will examine various aspects of the machine and its installation:

• Premises wiring and machine wiring compliance with NEC and NFPA 79 standards
• Safety devices, enclosures, components, and materials must meet industry standards such as ANSI, NEMA, and CSA
• Construction and installation evaluation, including visual inspections of components like wiring, protection, grounding, and labeling

Field Evaluation Inspections: What Gets Checked

Field evaluations include a thorough inspection of the following:

1. Suitability for Installation: The machine must be safe and appropriate for its intended environment.
2. Mechanical Strength: Evaluating durability and protection levels of parts.
3. Electrical Safety: Examining wiring, insulation, and potential hazards like arcing.
4. Construction & Installation: Ensuring proper wiring sizes, protection, and labeling.

If all these criteria are met, the machine should pass the certification inspection and be granted an NRTL label.

Handling Non-Typical Evaluations

In some cases, machines or controls may fail the field evaluation. If this happens, a correction plan is created, and the machine must be modified accordingly. These modifications are documented and evaluated to ensure compliance.

Additionally, some users might implement extra safety measures as part of their Electrical Safety Program. While these modifications are generally acceptable, they must be evaluated by the technician.

Special Considerations for Oregon Code

In Oregon, an additional UL 508 label may be required for certain machines. If needed, Lone Pine USA can connect you with certified technicians who can review, fix, or finalize control panels for certification under this label.
