NRTL certification. What U.S. industrial sites require.
OSHA listing, UL 3300, ANSI/RIA R15.08, and how Quarero's European certification stack maps onto U.S. compliance. The honest version, not the marketing version.

What NRTL actually means
NRTL stands for Nationally Recognized Testing Laboratory. It is the OSHA program that designates third-party labs (UL, Intertek, CSA, TÜV SÜD America and others) to certify that electrical and electronic equipment meets U.S. safety standards. For mobile autonomous robots, the relevant test scope is UL 3300 plus ANSI/RIA R15.08.
Strictly, NRTL listing is required for any electrical product whose installation is regulated by an Authority Having Jurisdiction. In practice, NRTL-listed robots clear procurement, insurance and OSHA inspection at U.S. industrial sites without friction. Non-listed robots can be deployed but face higher liability exposure and slower onboarding.

The standards stack a U.S. security robot must meet
| UL 3300 | Service / autonomous mobile robots — U.S. safety standard |
| ANSI/RIA R15.08 | Industrial mobile robots — operational safety |
| OSHA 29 CFR 1910 | General industry workplace safety regulation |
| EN ISO 13482 | European equivalent · Quarero current certification |
| IEC 60950 / 62368 | Electrical safety baseline |
| FCC Part 15 | Radio-frequency emissions |

Where we stand today
Quarero QR-series robots are certified to the European safety stack: EN ISO 13482 for service-robot mechanical and electrical safety, EU Machinery Regulation 2023/1230, CE marking, TÜV SÜD audit. This stack is mature, audit-ready and accepted across DACH and EU jurisdictions.
NRTL listing for U.S. deployment is on the 2026 product roadmap. Path: UL 3300 audit plus ANSI/RIA R15.08 operational-safety review, plus FCC Part 15 emissions test. Estimated audit window 4-6 months from kickoff. Customers planning U.S. pilots in late 2026 should engage now so the listing lands ahead of deployment.

Why EN ISO 13482 is not enough for OSHA
EN ISO 13482 and UL 3300 overlap substantially in coverage but are not mutually recognized. A CE-marked robot deployed in the United States still requires separate NRTL listing to satisfy OSHA and local AHJ requirements. The technical content is largely transferable, which is why the second audit is faster than the first — but it is still a separate audit.
Insurance carriers in the U.S. ask for NRTL listing as a tick-box requirement before underwriting industrial robotics deployments. Without it, premiums rise or the policy carves out the robot entirely.
