Standard for Transients Test Method
Scope:
Note: The title, ICS code, scope & project need of this Notice of Intent (originally published on November 16, 2021) were updated by the responsible SDO on October 22, 2024.
These requirements cover the transients test method for fire, security, and life safety equipment. These tests include supply line (ring wave surge voltage) transients, Internally induced Transients, Sequential Arc Transients, Radiated Electromagnetic Fields, Field-Wiring Transients, Surge Immunity Test (Combination Wave), Surge Current Test, and Static Discharge Test. Tests conducted in accordance with these requirements are intended to demonstrate that the intended operation of the device is not impaired (electromagnetic compatibility (EMC)) when subject to electromagnetic interferences (EMI) generated by the specified test method, devices and/or appliances outlined in this standard. These requirements cover the circuits. ports, or surfaces being subjected to the relevant tests unless otherwise specified in the end product standard.
Project need:
UL proposes a new joint Canada-US national standard for the transients test method. This standard will be covered by the TC on Test Methods for Fire Safety Equipment. The TC will consist of Canadian organizations representing regulators, users, and manufacturers.
