Classification introduction of ULCSA certification

The American Safety Testing Laboratory Corporation (UL) was established.

During the period of 1890, a series of serious fires occurred in many cities in the United States, which were all attributed to the fires of electrical equipment and wires.

In order to avoid the recurrence of the tragedy, Mr. Williams Merrill founded the Underwriting Electrical Engineering Bureau in 1894, the predecessor of the Electrical Engineering Bureau of the National Fire Bureau. On March 24th of the same year, UL released its first test report with only two employees and test equipment worth $350.

190 1 year, the Engineering Bureau founded by Mr. Merrell was reorganized into Underwriters Laboratories Inc, and the testing field expanded beyond electronic motors.

UL listing label

This is one of the most commonly used UL tags. If the logo is attached to the product, it means that the product sample meets the safety requirements of UL. These requirements are mainly the safety standards published by UL itself. This type of mark usually appears in the following products: electrical appliances, computer equipment, stoves and heaters, fuses, power boards, smoke and carbon monoxide detectors, fire extinguishers and automatic sprinkler systems, personal floating equipment such as life jackets and lifebuoys, bullet-proof glass and thousands of other products.

C-UL listing label

This logo is suitable for products sold in the Canadian market. Evaluate products with this mark according to Canadian safety requirements. Canada's security requirements may be different from those of the United States. This sign can be seen on the following types of equipment: electrical and computer equipment, vending machines, household burglar alarm systems, lighting equipment and many other kinds of products.

C-UL American column name label

UL introduced this new listing mark at the beginning of 1998. It says it meets the requirements of the United States and Canada. The Canadian/American logo is optional. UL encourages manufacturers whose products are certified in the United States and Canada to use this new combination mark, but manufacturers can choose to continue to use the UL mark only applicable to the United States or Canada.

Grading mark

This logo appears on products that have been evaluated by UL. UL evaluated some special properties of the products marked with the logo. Some special properties here refer to properties suitable for use in a limited danger range or under limited or special conditions. Generally, products classified by UL belong to general building materials and industrial equipment. For example, the equipment types classified by UL are diving suits, fire doors, firemen's protective devices and industrial trucks.

C-UL classification mark

UL introduced this new classification mark at the beginning of 1998. It says it meets the requirements of the United States and Canada. The Canadian/American logo is optional. UL encourages manufacturers whose products are certified in the United States and Canada to use this new combination mark, but manufacturers can choose to continue to use the UL mark only applicable to the United States or Canada.

Approved component marking and Canadian approved component marking.

Ordinary consumers rarely see these signs because they are used in parts, which are parts of some larger products or systems. These parts themselves cannot directly constitute a complete product, or their uses are limited. Parts certification marks can be seen in many products, including some switches, power supplies, printed circuit boards, some kinds of industrial control equipment and thousands of other products. Products intended to be sold in the Canadian market are labeled with approved parts with the letter "C".

Used to mark parts approved by Canada and the United States.

This is a new UL approved part mark, which came into effect on April 1998. According to the requirements of Canada and the United States, it can be used for UL certified parts. At first, UL did not intend to introduce the combined certification component logo, but introduced this new logo, because UL certificate users whose products are sold to Canada and the United States like the Canadian/American list and grading logo very much.
