Whether you are developing product to be sold locally or internationally, knowing the relevant product safety standard is important. Safety standards for industrial control equipment (ICE) are being harmonized to increase global market access.
The result of this harmonization process is detailed in the table below. The table identifies the affected product categories and the corresponding harmonized standard to which they will be transitioned, along with other information needed.
** Start Date – Date when the new Standard(s) may be used for Certification; End Date = Date when UL 508/508C is no longer an option for new and alternate construction product investigations.
## – These Standards have been published and are available for use towards Certification. Details regarding the transition schedule, bulletins and associated FAQs will be provided in the future.
Unless indicated in one of the above-mentioned transitions, if you currently have a product certified to UL 508 or UL 508C, under one of the affected categories, please contact UL by the requested date to convert your existing file to the appropriate harmonized standard(s). Contact your local sales representative to request a quotation, click here, or use the Contact UL button on this page.
Please note that if you have any product or sales literature that references UL 508 (or UL 508C), you should consider revising such literature to reference the new corresponding harmonized standard.
Please be certain to review this website regularly for updates to the current and new standard transitions.
