Become a UL Listed panel shop

UL's Industrial Control Panel (ICP) custom builder program allows manufacturers who custom-build or mass-produce ICPs to apply the UL and C-UL Listing Marks at their factories. Our program makes it convenient to receive a UL Listing while allowing maximum flexibility in panel design. UL's safety Marks are the most credible and sought after certification marks in North America. When regulators, specifiers and end-product certifiers see the familiar UL Mark, they are confident that the panel has met the certification requirements. Learn more.

Electric/electronic control equipment

UL provides certification services to assist electrical/electronic control equipment manufacturers in gaining access to the domestic and global markets. Our electrical/electronic control equipment team is constantly developing new tests and procedures to stay at the front of the safety industry. UL works closely with numerous panels, councils, and other electrical/electronic control equipment organizations, and has a representative on each of the National Electrical Code panels.  Learn more.

Electric vehicle components

In the late 1990s, UL joined forces with the automotive and utility industries to help develop the infrastructure for electric vehicles and their charging systems. Efforts underway include the development of requirements for EVs and their charging systems so that consumers driving and charging these vehicles can be confident of their safety. As UL has become recognized as the premier third party safety testing organization, the American and Japanese automotive industries have called upon UL to evaluate EV charging systems and components.  Learn more.

Functional safety

As systems rely more and more on sophisticated hardware and software, safety is increasingly dependent on the relationship between products and their responses to inputs. Functional safety depends on equipment or a system operating correctly in response to its inputs. Neither overall product safety nor functional safety can be determined without carefully evaluating a product's systems as a whole and assessing the environment with which they interact. Learn more.

Industrial control equipment

The term "industrial control equipment" encompasses more than 30 different product categories and 100 different devices. This can make finding out where your product fits in, what specific requirements apply, and how to interpret those requirements a complicated process. UL can help you identify the UL and IEC Standards that are needed for your specific industrial control product, answer your design questions about UL 508, the Standard for Safety of Industrial Equipment, and help you find the resources to answer your technical questions.  Learn more.

Robots and robotic equipment

Robots today are not just manipulator arms, they come in many shapes and sizes. Sometimes it can be difficult to tell if a product is a robot.  Learn more.

Semiconductor manufacturing

UL offers a variety of services for the semiconductor industry including UL Certification, MAS field evaluation services and SEMI S2 compliance.  Learn more.

61010 Bulletin information

On July 12, 2004,  UL published the new second-edition of the Standard: Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use, UL 61010-1, Part 1.

This Standard combined three existing UL Standards - UL 61010A-1 for laboratory equipment, UL 61010B-1 for test and measurement equipment, and UL 61010C-1 for process control equipment into a single Standard, UL 61010-1, that is totally aligned with the current edition of IEC 61010-1 applying to the same equipment, except for some National Differences.  UL 61010-1 received approval as an American National Standard upon publication. The standard is co-published in the United States with the International Society of Automation (ISA) and with the Canadian Standards Association (CSA) in Canada.

As a new edition, UL 61010-1 has an effective date of January 1, 2014.  Due to the impact on Listed or Recognized equipment of this effective date, a compliance schedule, which was developed to give manufacturers time to integrate potential changes into their products or allow other products to go out of production, was published in our Bulletin dated July 23, 2004. Equipment Listed or Recognized to UL 61010A, UL61010B, or UL 61010C, will have to comply with the requirements in UL 61010-1 in accordance with this schedule.

Important dates from this schedule are now close at hand. Manufacturers can submit products for Listing to the requirements in UL 61010A-1, UL 61010B-1, UL 61010C-1 only until December 31 of this year. On January 1, 2010 all new product and alternate construction submittals will have to be to UL61010-1. A bulletin has been sent to all clients announcing the upcoming dates.
