It plays a pivotal role in reducing the potential for liability in case of an accident. In the grand scheme of things, opting for an industrial PC or an automation device with UL certification provides peace of mind and, in turn, bolsters confidence in the system’s safety, reliability, and performance.

As humanity strides boldly into the fourth industrial revolution, UL and other safety compliance certifications have emerged as a ubiquitous norm across a multitude of products. The various symbols and markings adorning the rear of electronic gadgets, household appliances, and akin commodities serve as reassuring emblems, assuring end users that these products have undergone rigorous safety testing prior to deployment. In the vast realm of industrial applications and deployments, the presence of a safety marking becomes indispensable for ensuring competent operations, encompassing:

• Industrial/Factory Automation
• Medical Inferencing
• NVR Surveillance
• Smart Kiosk Machines
• Vehicle Fleet Telematic

& more.

When it comes to devices, particularly electronics, the absence of safety marks should serve as a warning. It indicates that the respective company has chosen not to subject their products to rigorous safety compliance testing. As mentioned earlier, system failures and downtimes exact a heavy toll, resulting in unwelcome complications. Safety marks provide peace of mind, assuring consumers that the product has undergone meticulous scrutiny in adherence to stringent regulatory standards.

UL Listed: The entire product or system has undergone and met the full UL safety standard guidelines.

UL Recognised: A component (expected to be integrated into a larger system) meets UL safety standard guidelines.

However, when integrated into the larger system, the system as a whole is not UL certified.

Within the realm of UL safety marks, a range of certifications exists, including UL marks tailored to regional standards. One common source of confusion lies between UL Listed and UL Recognized. To clarify, UL Listed signifies that a standalone product has undergone rigorous testing, ensuring it complies with safety standards and guidelines. Conversely, UL Recognized is applicable to components or materials intended for integration into a larger system. These marks are particularly valuable to system integrators in their quest for validated components to construct complete systems.

To illustrate, consider a power supply for a computer, which may bear the UL Recognized mark as it forms part of a larger system. In contrast, a washing machine, being a self-contained product, may earn the UL Listed designation. In the context of industrial computers, they are typically UL Listed since they are not only capable of integration but are also fully functional as standalone units.

UL Classification represents a distinct mark wherein a product undergoes assessment based on a specific attribute, be it fire resistance or impact resistance. This implies that a product bearing the UL Classified mark has been subjected to testing against a single attribute or a portion of the comprehensive UL standards list, rather than the entirety of the UL testing procedure. Due to its limited scope in testing, this certification is regarded as the fundamental tier of safety. UL Classified products do not undergo evaluation for safety in any other aspect apart from the particular property they are certified for.

An example of a UL Classified product is a security door evaluated for resistance against bullets (UL 752) and fire resistance (UL 10C). It’s crucial to note that this designation doesn’t elevate the security door to being UL Recognized or UL Listed, as it hasn’t undergone the exhaustive full-scale testing procedure.

Underwriter’s Laboratories has acknowledged a common challenge for end users and consumers: the complexity of deciphering multiple certifications on products, not only from UL but also from various testing organizations. This jumble of certifications can be bewildering. To address this, their latest and improved UL Certified mark offers enhanced clarity. An optional QR code facilitates quick access to additional details, enhancing transparency. The enhanced UL Certified mark is applicable to UL Listed and UL Classified products, but not UL Recognized.

So, what sets UL Listed and UL Certified apart? UL Certified acts as an all-encompassing mark that covers both UL Listed and UL Recognized products. This thoughtful strategy ensures a consistent identification of the UL mark for end users and offers easy access to supplementary information via the convenient QR code.

While UL is primarily recognized for its association with products intended for the North American market, it boasts a worldwide presence thanks to its collaborations with international bodies and standards organizations. Each UL certification mark is region-specific, designed to align with both the standards set forth by the International Electrotechnical Commission (IEC) and the distinct national standards of the targeted region.

The IEC, comprising 60 countries, plays a pivotal role in creating and establishing international standards that all its member nations must adhere to. National standards, on the other hand, are typically rooted in or closely aligned with IEC standards, though they may incorporate modifications tailored to the unique safety requisites of specific regions. Since each country or region maintains its own set of established standards, UL-Listed logos come accompanied by a regional mark, clearly indicating the national standards with which the product complies.
