UL continues to advance and support hazardous locations safety science research around the world. We provide customers and industry associations with extensive research services for unique areas of focus. We also conduct our own independent research to help inform manufacturing practices and standards.
Research has served as the foundation for our hazardous locations services since the early days of UL.
Our first hazardous locations bulletin of research was published in 1937 on the topic of floating dust in grain elevators. Over the subsequent decades, hazardous locations research has spanned a variety of explosion protection issues. One key research effort involved the determination of explosive properties of dust based on testing, utilizing a custom-designed vessel.
Another key research effort involved the determination of explosive properties of chemicals based on testing, utilizing a custom-designed vessel known as the Westerberg Explosion Test Vessel (WETV). This research into explosive properties served as the basis for the current grouping of materials in NFPA 70 and NFPA 497.
Recent research efforts are focusing on issues such as measuring temperatures on LED array surfaces, ignition properties of alternative refrigerants, spark ignition test results involving elevated temperatures, and current flow through combustible dusts.
As active members of industry associations and codes and standards committees such as API, IEC, IEEE and NFPA, we are uniquely positioned to connect all stakeholders, from manufacturers to inspection and regulatory authorities. As industry needs change and technology evolves, we are involved in studying and sharing the potential impacts on markets, customers, standards and, above all, safety.
At our state-of-the-art research facilities, including the only laboratory in the world for explosive dust testing involving grain and magnesium dust, we are committed to helping keep safety ahead of innovation as a trusted advisor and authority.
New research opportunities are always under consideration. Contact us if we can help your company or your industry.
