I NTRODUCT I ON CERTIFICATION MARKINGS

Similar to equipment marking, country specific marks are used by UL and CSA to identify approved components. Component Marks (products must be installed with other equipment) US Canada Canada & US UL

After a review in 2020, IECEx decided to use a single mark for both marketing purposes and to indicate equipment compliance. When used in print material (including literature, website, media publication, etc.) there are no licensing requirements. However, the mark cannot be used on equipment, product packaging, business cards, letterhead, stationary, etc. (except for certain IECEx members) unless a license is obtained through the IECEx Mark licensing Scheme. The requirements for equipment marking include those identified in The IEC 60079 Series and the inclusion of the IECEx Certificate of Compliance Number.
