UL 60335-2-40 4th Edition Flammable Refrigerant Requirements | HVAC Webinar

This webinar provides an essential and timely overview of the UL 60335-2-40 4th Edition standard as the HVACR industry transitions to alternative, low-Global Warming Potential (GWP) refrigerants, which are often mildly flammable (A2L). Participants will learn about regulatory drivers, how to identify and mitigate potential ignition sources like hot surfaces and electrical components, and the critical role of Simulated Leak Testing (Annex FF & MM) in ensuring compliance. You will gain a clear understanding of the requirements for Refrigerant Detection Systems and the strict time limits for mitigation actions, equipping you to design and certify safe, modern HVACR appliances.

Ensure your products are designed for safety, meet compliance expectations, and remain competitive in a rapidly evolving HVACR landscape. Download this free, expert-led webinar for a deep dive into how the standard impacts components used in HVACR equipment construction.
