UL 1412:2022 PDF Download

The UL 1412:2022 standard outlines the requirements for fusing resistors and temperature-limited resistors used in radio- and television-type appliances. The purpose of this standard is to reduce the risk of fire or electric shock when utilizing these resistors. It should be noted, however, that compliance with these requirements does not automatically guarantee suitability for all applications without further evaluation within the appliance.

The scope of this standard includes not only the resistors themselves but also the resistor mounting assemblies intended for use with them. These requirements are applicable to circuits within radio- and television-type appliances that involve potentials below 2500 V peak.

One important point to note is that section 1.3 of the standard has been deleted as of January 21, 2004. This suggests that there may have been changes or updates made to the standard after that date. It is important for manufacturers and users of these resistors to stay updated on the latest versions of the standard to ensure compliance and safety.
