UL certification

UL number on PCB

UL is the certifying agency for product safety in the United States of America. The Underwriters Laboratories (UL) test products worldwide according to corresponding U.S. product safety requirements, so that these products may be marketed and sold in every part of the United States of America and Canada.

The UL Mark is the most widely accepted proof that a product meets American and Canadian safety requirements. For North American consumers, regulators and manufacturers, the UL Mark is a recognized symbol of product safety. More than 17 billion UL Marks appear every year on new products.

If you wish the UL identification to be applied to your circuit boards, simply specify this as option within our PCB Calculator.

UL certification of Multi-CB

Nearly all circuit boards made by Multi-CB are manufactured using a UL 796 certified process according to ZPMV2 (USA). FR4-based printed circuit boards also have the ZPMV8 (Canada) certificate. These circuit boards may be integrated into UL approved products, which may then be marketed without any difficulty in the United States of America and Canada.

Multi-CB’s UL identification number is E198312.

At Underwriter Laboratories you will find:

Application of the UL identification is included for new orders; application of the UL identification on subsequent (re-orders) may incur processing costs. 

The completed products are certified according to fire safety class UL (796) 94 / V0. UL 94 is harmonized with IEC 60707, 60695-11-10 and -20 as well as the Canadian CAN/CSA C 22.2 No.017.

UL certification for Metal core circuit boards

Single-sided and double-sided plated-through metal core circuit boards are also available with the UL  certification of Multi-CB (E198312).

UL certification for Flexible and Rigid-Flex circuit boards

Flexible boards and flexible multilayers as well as Rigid-Flex circuit boards are manufactured using a UL 796 certified process according to ZPXK2 (USA). Multi-CB’s UL identification number for Flex and Rigid-Flex circuit boards is: E489719.
