UL- Underwriters Laboratories

History of UL


In 1894 William Henry Merrill founded Underwriters Laboratories. Otherwise known as UL for short. “Underwriters’ Electrical Bureau” was its original name. Then, in 1903 they published their first literature on safety. It was titled “Tin-Clad Fire Doors”.

The safety lab leaped into modern testing. Their certification of the first motor-driven phonograph was in 1907. As a result of keeping up with the times, one hundred years later they made another leap, testing of the modern CD player.

Recognition of the Testing Lab

Underwriters Laboratories has become the best-known independent testing lab in the world. Therefore, UL performs testing on a wide range of products. Their testing procedures assess the quality of the individual product as well as level as safety.

According to their website “UL certifies, validates, tests, verifies, inspects, audits advises and educates.” UL performs all of these functions through their testing services. Especially for those looking to ensure their products comply with regulations as well as safety.

The UL Certification is not only recognized in the U.S., it also services companies worldwide.

UL and International Influences

There is the same level of safety for products in the U.S.A. as those going outside of the states. UL studies international certification standards.

Furthermore, UL has made a strong effort to standardize safety requirements. They have also made an effort to standardize protocol. These are as well as certifications around the world.

A Testing Lab

Underwriters Laboratories is very adamant about clarifying something.

UL wants it well expressed that they are a testing lab. They are not an approval lab. Also, they are not a government agency.

They do not have the right to approve any product for a consumer. However, their certification process is held at a high level. Due to this, the government takes their certification into account during the approval processes.
