Q: What does UL's Low Smoke Halogen Free (LSHF) dual rating mean?

A: Low Smoke Halogen Free (LSHF) certification from UL indicates that all of the combustible materials used in the construction of a cable are Halogen Free and the cables also comply with the requirements for low smoke when tested in accordance with IEC 61034-2 (International Standard for the Measurement of Smoke Density of Cables under Defined Conditions). Proterial is the first to offer a LSHF-Riser dual-rated listing for NanoCore™ multi-unit fiber optic cables, in accordance with the latest version of UL 2885 based on the IEC 62821 -1, -2 & -3 standards. The latest standard consolidates all existing standards and tests for LSHF cables as well as additional requirements. The standard is valid not only for the cable but also for any compounds or materials used in the cable.
