Splicing modules must meet which fire rating standard?

Explanation:
Splicing modules use plastic housings, so their ability to resist fire is determined by the flammability rating of the plastic material. UL94 is the standard that tests and classifies how materials burn in electrical equipment, with ratings like V-0, V-1, and V-2 that indicate progressively less flame propagation and afterglow. This makes UL94 the right measure for ensuring the plastic parts of a splice module won’t contribute to a fire. UL50, by contrast, deals with enclosure ratings (how well a cabinet or enclosure protects against environmental factors), not the material’s burning behavior. UL1077 covers supplementary protectors, and UL1449 covers surge-protective devices. Those do not address the fire performance of the module’s plastic components.
