UL Publishes the 15th Edition of UL 48
On Friday, Underwriters Laboratories announced publication of the Fifteenth Edition of the Standard for Electric Signs (UL 48). Because of the scope of revisions, this edition represents an important milestone in development of the standard. ISA members serving on the UL 48 Standards Technical Panel have been instrumental in updating this standard. In addition to contributing to a successful outcome on UL 48, ISA continues to exert a positive influence on development of the NEC. This includes current efforts by ISA to develop formal proposals for changes in the 2014 NEC. For more information, please contact [email protected].
