UL Statement on MI vs Soft Skinned Fire Resistant Cables
UL Public Notice Released the following Statement on September 12, 2012 
“UL has recently conducted research on a wide array of current products and systems originally certified under UL 2196, Tests for Fire Resistive Cables and ULCS139, Standard Method of Fire Test for Evaluation of Integrity of Electrical Cables and determined that they no longer consistently achieve a two-hour fire-resistive rating when subjected to the standard Fire Endurance Test of UL2196 or ULC-S139. Consequently, UL and ULC will not be able to offer certification to the currently existing program related to these standards. As a result, manufacturers are no longer authorized to place the UL mark or ULC mark on the following products:
- UL Classified Fire Resistive Cable (FHJR)
- ULC Listed Fire Resistant Cable (FHJRC)
- UL Listed cable with “-CI” suffix (Circuit Integrity)
Furthermore, UL has removed from its certification directory all Electrical Circuit Protective Systems (FHIT) constructed with Fire Resistive Cable”
