Manufacturers now have the possibility of a shorter testing timeline for the certification of their electrical insulation systems. UL’s Defined Life Thermal Aging (DLTA) certification program can help reduce testing times and, as a result, increase speed to market. This program is intended for insulation systems that are used in applications where the operational designed service life is 5,000 hours or less. The DLTA program offers an alternative to the full thermal aging program and is used to evaluate an EIS with a design life of 1500, 2500, 4000, or 5000 hours. Learn more HERE.
