The initial UL standard will be accredited as a National Standard in the U.S. and Canada. However, as a voluntary third-party standard, this can be used in any region or country. UL intends to pursue international standardization and/adoption as they have for other standards after the first version of the standard is completed. The Standards Technical Panel (STP) is expected to include representatives from the US, Canada, Europe, and Asia. Additional non-voting stakeholder representatives are welcome from around the world.
