Our HazLoc field-based services cover North America and other regions
Our team of highly skilled engineers travels to the final installation site to evaluate pre-installed equipment throughout North America. We can also travel to other regions to pre-review equipment before relocating or shipping equipment to North America.
Unit Verification Certification
Across North America and Europe, our field team offers unit verification certification methods for the ATEX and IECEx certification systems for customized equipment in a potentially explosive atmosphere.
Limited-Production Certification (LPC)
We offer UL’s Limited-Production Certification (LPC) for a custom-built or limited quantity of products in North America. We can also travel to other regions to inspect, test, and certify equipment before relocating or shipping equipment to North America.
Our skilled field team executes a comprehensive process including:
- Reviewing the design, documents and certificates for the individual pieces of equipment.
- Examining the construction and testing the equipment on-site or at the factory.
- Inspecting all units covered by the certification. Note – Verifying the quality management process for producing this equipment is unnecessary.
- Labeling equipment with serialized marks and providing certificates declaring equipment compliant.
