| Sheet / roll |
Woven HDPE black fibres fabric, double-side lamination with LDPE coating, reinforced
with six bands of 75 mm width woven black HDPE fibres fabric and coated outside.
Pre-punched 8 mm holes on the two side bands at 0.1 m +/-10% intervals, positioned
in the centre of the bands (only the reinforcement bands are pre-punched,
not the tarpaulin itself).

| Tensile strength |
Min 500 N, 15-25% 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 475 N |
| Reinforcement bands |
Min 700 N as per ISO 1421-1, pulling lengthwise in a prepunched 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 665 N. |
| 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 400 N |
