Why is UL Listing Important?

2016-09-06 10:54:35

“UL” stands for Underwriters Laboratories, Inc,  which is an independent product safety certification organization established in Chicago in 1894.  Originally known as the Underwriters Electrical Bureau, UL has since expanded to include 182 service centers in more than 100 countries.


UL provides certification and follow-up services to manufacturers  that are easily identifiable by consumers. Manufacturers must submit a design layout of the UL mark to a UL label center for review to make sure all required information is acceptable. UL has developed standards and test procedures for products, materials, components, assemblies, tools and equipment, all dealing with product safety.  Underwriters Laboratories perform safety testing on 18,750 categories of electrical, mechanical and chemical products.


Underwriters Laboratories Inc. (UL) is one of the several companies that are approved for such testing by the US federal agency Occupational Safety and Health Administration (OSHA). OSHA maintains a list of approved testing laboratories, known as Nationally Recognized Testing Laboratories.



Why is UL Listing Important?

UL is a name you can trust! Consumers can be confident that their seal of approval is not a superficial sales ploy because Underwriters Laboratories is a third-party, not-for-profit organization with no financial interest in the products they evaluate.


UL goes the extra mile by continuous product safety evaluations, even after a product’s initial rating is published. From time to time, UL representatives participate in unannounced visits to manufacturers to evaluate already-listed products to determine whether or not safety standards are being maintained. If a product no longer satisfies the requirements of the UL, the listing is taken away.


The following principles drive every decision we make at UL:

1. Promoting safe living and working environments by the application of safety science and hazard-based safety engineering

2. Supporting the production and use of products which are physically and environmentally safe and to apply our efforts to prevent or reduce loss of life and property

3. Advancing safety science through research and investigation

4. Concentrating our efforts and resources on public safety in those areas where we can make valuable contributions

5. Working with integrity and a focus on quality to enhance the trust conveyed by our certification marks and services

6. Charging fair prices that allow us to meet our obligations, sustain our growth, and invest in safety science and education

7. Investing in our people and encourage our people to invest in themselves

8. Being a good example of corporate citizenship and social responsibility” 

You now know that the UL mark is a symbol of trust! You can be confident when purchasing products with a UL listing mark!




Jaapson PCB is a strong advocator for UL compliance.

PCB, as the most important component in every electronic product, its safty determines if the whole product is safe or not. We are proud that Jaapson passed UL certificate and always adhere to UL standards to make sure that our employees, our customers, and end-users, comsumers are safe with us.
