UL or Underwriters Laboratory certification means it has passed a series of tests to ensure a product's safety. This provides a safeguard to ensure that products are not potentially harmful to consumers.
A UL Mark is a type of certification mark which is used in the United States. The UL Mark is used on many products to certify them and the UL Mark product is the most widely used and accepted certification product mark.
UL and ETL are both independent organizations that provide certification for electrical products, but there are some key differences between their certification processes. UL certification is more widely recognized and has been around longer, while ETL certification is newer but gaining popularity. UL has its own testing facilities, while ETL relies on third-party labs. Additionally, UL certification typically takes longer and is more expensive than ETL certification. Ultimately, both certifications ensure that electrical products meet safety standards.
ETL certification and UL certification are both third-party certifications that ensure products meet safety standards. The main difference is that ETL is a mark provided by Intertek, while UL is a mark provided by Underwriters Laboratories. Both certifications indicate that a product has been tested and meets specific safety requirements, but they are issued by different organizations.
ETL and UL are both certification marks for electrical products, indicating they have been tested for safety. UL is a more widely recognized certification, while ETL is newer but also reputable. Both certifications ensure that electrical devices meet safety standards, but UL is more stringent in its testing process. Having either certification indicates that a product is safe to use, but UL may provide a higher level of assurance.
To conduct a UL number lookup for a specific product, you can visit the UL website and use their online database search tool. Enter the UL number or the company name associated with the product to find the relevant information and certification details.
Fire alarm systems that are UL tested and listed per UL827 and NFPA 72.
UL stands for Underwriters Laboratories, a non-profit organisation. Basically what they do is test different parts of products (AC Cord, microchips etc) and see if they are susceptible to catching on fire. UL certification does not guarantee that a product will function 100% properly, but they put their stamp of approval on items that are known not to catch fire during normal usage.

No, as a general rule. Even if it were possible, doing so would invalidate the certification from a recognized testing service such as Underwriters' Laboratories (UL), CSA, TVE, etc. Your writer worked for UL one summer during college and came to understand firsthand why certification by a testing service is essential. Whenever I buy a plug-in electrical appliance, my personal rule is that it must have the UL mark or label on it.
