OSHA Expands Testing Lab Recognition for Nemko North America
OSHA Expands Testing Lab Recognition for Nemko North America
What Changed
OSHA has officially granted Nemko North America, Inc. (NNA) an expansion of its scope of recognition as a Nationally Recognized Testing Laboratory (NRTL). The decision, published in the Federal Register on February 18, 2026, allows NNA to test and certify products against three additional safety standards.
The expansion became effective immediately upon publication.
Why NRTLs Matter for the Chemical Industry
Nationally Recognized Testing Laboratories are organizations that OSHA has approved to test and certify equipment and products used in U.S. workplaces. If your facility uses electrical equipment, pressure vessels, safety devices, or laboratory instruments, chances are they carry an NRTL certification mark.
For chemical operations specifically, NRTL-tested equipment includes:
- Explosion-proof electrical equipment — Required in areas where flammable vapors, gases, or dusts may be present
- Fume hoods and ventilation systems — Laboratory and industrial ventilation equipment used with hazardous chemicals
- Safety relief valves — Pressure-relief devices on chemical storage tanks and process equipment
- Analytical instruments — Lab equipment used for quality control testing of chemical products
Details of the Expansion
NNA originally submitted its application on July 30, 2024, requesting recognition for three additional test standards. OSHA published the preliminary notice in December 2025 and opened a public comment period through January 15, 2026. No comments were received, and OSHA proceeded with the grant.
The document was signed in Washington, D.C. on February 12, 2026, by Douglas Parker, Assistant Secretary of Labor for Occupational Safety and Health.
What This Means Going Forward
More NRTLs with broader recognition scopes means more testing capacity and potentially faster product certifications for manufacturers. For chemical facilities purchasing new equipment, this is a positive development — it expands the pool of labs that can certify the specialized equipment used in hazardous environments.
Facilities should verify that any equipment they purchase for use in hazardous classified areas carries a valid NRTL certification mark from a recognized laboratory.
Alliance's Take
NRTL certifications may seem like an administrative detail, but they're a critical link in the safety chain for anyone handling chemicals. The equipment your team uses every day — from fume hoods to explosion-proof lighting — depends on independent testing labs to verify it's safe for use in chemical environments.
At Alliance Chemical, we take a similar approach to product quality: every chemical we ship comes with a Certificate of Analysis (COA) and Safety Data Sheet (SDS) so you know exactly what you're getting. Whether you're outfitting a laboratory or a production facility, documentation and certification matter.

Frequently Asked Questions
What is the significance of the OSHA expansion for Nemko North America?
OSHA has officially expanded the scope of Nemko North America as a Nationally Recognized Testing Laboratory. This decision allows the organization to test and certify products against three additional safety standards. For industrial facilities, this expansion increases testing capacity and may lead to faster product certifications for specialized equipment used in hazardous environments.
Why are NRTL certifications important for chemical facilities?
Nationally Recognized Testing Laboratories ensure that equipment used in chemical operations, such as explosion-proof electrical gear and fume hoods, meets rigorous safety standards. These certifications are critical for maintaining safety in areas where flammable vapors or gases are present, as they verify that instruments and safety devices are safe for industrial use.
What types of equipment require NRTL testing in hazardous environments?
In chemical and industrial settings, NRTL-tested equipment includes explosion-proof electrical devices, laboratory ventilation systems like fume hoods, and safety relief valves for storage tanks. Additionally, analytical instruments used for quality control must carry these marks to ensure they are safe for operation within potentially hazardous or regulated workplace environments.
How should facilities verify the safety of their new laboratory equipment?
Facilities purchasing new equipment for hazardous classified areas should verify that every product carries a valid certification mark from a recognized laboratory. This documentation confirms the equipment has undergone independent testing. Checking for these marks ensures compliance with OSHA standards and guarantees that devices like pressure-relief valves or ventilation systems are safe.
