When it comes to industries that are mostly dominated by electrical products and other related products — like the HVAC industry — it is incredibly crucial that the businesses in these industries abide by certain standards in manufacturing their products. Additionally, it is also equally crucial that these products are tested and certified that their quality is top-notch. All this is important so as to assure that the products manufactured and sold are not defective, and so, they won’t suddenly malfunction and cause some problems to the users. Basically, without standards and certifications, sub-par electrical products would be rampant, and damages and injuries would happen more frequently than we’d like. 

         Fortunately, there are numerous institutions nowadays that have established standards for electrical products. And these institutions also provide certifications to those products that have passed their tests. Out of all of these certification institutions, one that is incredibly well-known is the Underwriters Laboratories. 

What Is the Underwriters Laboratories (UL)?

         Simply put, the Underwriters Laboratories, or UL for short, is a global safety certification company that aims to “create a better world by applying science to solve safety, security, and sustainability challenges.” The company plans to achieve this goal by conducting rigorous independent research and analyzing safety data, convening experts worldwide to address risks, sharing knowledge through safety education and public outreach initiatives, and developing standards to guide the safe commercialization of evolving technologies. 

         UL was established in 1894, and since then, the company has served in about 104 countries, with main offices in 46 of them. Additionally, UL is one of several companies that are approved to perform safety testing by the U.S. federal agency Occupational Safety and Health Administration (OSHA). In fact, OSHA has currently maintained a list of approved testing laboratories, which are known as Nationally Recognized Testing Laboratories. 

What Are the Focus Areas of UL?

         UL has several focus areas in which the company conducts their tests for certifications. These focus areas are as follows: battery safety, chemical safety, data science, education and outreach, fire safety, and standards. 

Battery Safety 

         At a time when potentially risky energy storage technologies can be found in everything ranging from consumer products to transportation and grid storage, UL is helping to lay the groundwork for energy storage designs that are reliable and safe. The company achieves this goal by primarily conducting battery safety research and sharing data-driven knowledge to drive safe, reliable, and innovative designs to meet the world’s increasing energy demands. 

         In addition to academic publishing and dissemination of information through conferences and digital channels, UL also convenes diverse stakeholders to find solutions, such as through global batter summits and the Battery Safety Council, which is an organization co-led by the National Transportation Safety Board (NTSB) and UL. The organization also works with UL Standards to develop standards that factor in the most current safety and performance data.

Chemical Safety

         UL is guided by the idea that modern materials and technologies — however useful they are — should be studied to make sure that we understand the impact of their chemical composition and emissions on human health. And so, the company conducts research and collaborates with universities and other research and knowledge institutions. Additionally, UL chemical safety experts also seek to bring data-driven knowledge to scientific, business, and policy leaders, thereby raising their awareness of potential human health risks from rapidly emerging technological innovation. 

Data Science

         UL leverages data science to contribute to research, inform policy, and solve challenging safety, sustainability, and security issues. With this, the company collaborates with scientists, leaders, and data providers to spur innovation in the use of data to provide insights and solutions for their other focus areas. 

Education and Outreach

         UL advances innovative education programs, safety outreach, and science-based initiatives by identifying and helping to address the world’s most pressing safety threats through the connection of science and research. UL Education and Outreach programs serve as a catalyst for a global movement on safety, science, education, and collaboration through research and strategic opportunities. These initiatives will, in turn, inspire solutions that improve health and increase environmental sustainability, further engage and inspire the next generation of safety scientists and engineers, and, most importantly, help save lives.

Fire Safety

         The UL Firefighter Safety Research Institute (FSRI) collaborates with the global fire service to generate and share life-saving fire safety science knowledge that firefighters use every day to make better decisions in the life of duty. Additionally, UL FSRI investigates residential, commercial, and industrial fires through full-scale testing, field-testing, and modeling to replicate actual fire ground conditions faced by firefighters. The institute also further organizes fire service and other stakeholders with varied health and fire safety interests to raise awareness of issues and publish research findings on topics such as usage of specific firefighting tactics. 

Standards

         UL is a standards-setting organization, combining extensive safety research, scientific expertise, and input from stakeholders to advance safety science that leads to safe living and working environments. As such, UL develops and published consensus standards that guide the safety, performance, and sustainability of new and evolving technologies and services to deliver solutions for industries.

Moreover, UL is an accredited standards developer in both Canada and the U.S. under the designations ULC Standards and UL Standards. What this means is that UL is able to develop standards to advance safety, performance, and sustainability to meet stakeholder needs and bridge standards development gaps across North America.

Recognized Component Mark

         The “Recognized Component Mark” is a type of quality mark issued by Underwriters Laboratories. It is placed on components which are intended to be part of a UL-listed product, but which cannot bear the full UL logo themselves. The general public doesn’t really come across this mark since it is placed on components that make up finished products. 

Takeaway

         For businesses that are active in the HVAC industry, it is incredibly important that the products that they offer to their customers are of the best quality. After all, HVAC businesses don’t want their customers to experience problems or, worse, get injured because of a faulty product. Because of this, HVAC businesses must make sure that their products are tested and certified first before they are sold to the general public. Luckily, there are a lot of companies out there that specialize in testing and certifying products like the HVAC ones. And one of the most reputable is the Underwriters Laboratories (UL). 

         UL has been a global safety certification company since 1894, so you can expect that the company really knows everything about serving several industries. In fact, they have served companies in over 104 countries, and in 46 of them, UL has set up main offices. Additionally, with the wide scope of their services and the industries they cater to, UL has been recognized by several government agencies, particularly the U.S. federal agency OSHA, as one of the few companies that are approved to perform safety testing. 

         Basically, UL is a reputable certification company, and earning their approval for your products will add more credibility to your own HVAC business. For that reason, you should definitely consider enlisting UL to test and certify your products. That way, you will know for sure that your products are of high quality and that your customers will be satisfied with the performance of your products. And when that happens, your business is guaranteed to grow even further.
