A Standards for components

This Seventh Edition of the Standard for Transformers and Motor Transformers for Use in Audio-, Radio-, and Television-Type Appliances, UL 1411, is being issued as an Editorial New Edition update only. No changes to the requirements have been made.

These requirements apply to transformers, autotransformers, and motor-transformers intended to be used in audio-, radio-, and television-type appliances in which the primary winding is connected across the supply circuit.
