Construction
The LIQUID-TUFF™ LSZH Liquidtight Flexible Metal Conduit shall be formed from zinc coated galvanized low carbon steel strip having a uniform width and thickness. There shall be a continuous bonding strip built into the conduit core for the 3/8 through 11⁄4 trade sizes. The construction shall be in accordance with the UL® 360 Standard. The Low Smoke Zero Halogen designation shall be based upon testing to ASTM® 162 – Flame Spread Index, ASTM® E662 – Smoke Density Generation and Bombardier SMP–800C – Toxic Gas Generation. The finished LIQUID-TUFF™ LSZH Liquidtight Flexible Metal Conduit dimensions shall be in accordance with Table 5.1 of UL® 360
Jacket – TPU
A rugged low-smoke, moisture, oil, sunlight resistant and flame retardant thermoplastic polyurethane jacket shall be applied directly over the flexible metal conduit. The physical properties of the jacket material shall comply with the UL® 360 Standard. The Low Smoke Zero Halogen jacket shall be tested to and comply with ASTM® 162 – Flame Spread Index, ASTM® E662 – Smoke Density Generation and Bombardier SMP–800C – Toxic Gas Generation. The test results are summarized in Table 1. Underwriters Laboratories Inc. (UL®) does not List any manufacturers jacket compound as being low smoke zero halogen. The jacket wall thickness shall be in accordance with Table 4.1 of UL® 360.Description – Low smoke, zero halogen raceway – Low toxicity generation characteristics – Hot dipped zinc galvanized low carbon steel core – Excellent temperature ratings – Black thermoplastic polyurethane jacket – UL® copper bonding strip 3/8“ – 11⁄4” for grounding – Sunlight resistant – Flame retardant TPU jacket
