Sheet / roll |
Woven HDPE black fibers fabric, double-side LDPE coating, reinforced with 6 bands of 75 ±3% mm width woven black HDPE fibers fabric and coated outside.
Pre-punched 8 mm holes on the 2 side bands at 0.1 ±10% m intervals, positioned in the center of the bands (only the reinforcement bands are pre-punched, not the tarpaulin itself).
Flame retardant EN13823+A1. |
Tensile strength |
Min 500N, 15-35% elongation in warp and weft in plain sheet under ISO 1421-1. |
UV resistance |
After 1500 hours UV under ASTM G53/94 (UVB 313 nm peak) minimum 80% of original value of the actual product and not less than 475N. |
Reinforcement bands |
Min 700N as per ISO 1421-1, pulling lengthwise in a pre-punched 8 mm hole with a hook of 8 mm wire diameter, at 200 mm from the end of the band.
UV resistance 80% of original value and not less than 665N. |
Welding |
Only one is allowed, lengthwise. The tarpaulin tensile strength crossways at the place of welding under ISO 1421-1 minimum 50% of original value and not less than 400N. |
