| Material for the plain sheet |
Made of woven high-density black polyethylene (HDPE) fibers, warp x weft, laminated on both sides with low density polyethylene (LDPE) coating, with reinforced rims by heat sealing on all sides, (or 2 sides heat sealing and 2 sides double stitching), and a 3 to 5 millimeters diameter PE or PP (flexible materials) rope on the edge, inside the hem. 1000 denier minimum. |
| Material for the reinforced attachment points |
6 bands of 75mm +/-3% width made of woven black HDPE fibres fabric and coated with grey LDPE on the outside. Pre-punched 8mm holes on the 2 side bands at 0.1m +/-10% intervals, positioned in the centre of the bands (only the reinforcement bands are pre-punched, not the tarpaulin itself). Side bands can be positioned at maximum 10mm from the edge. Dimension tolerance on the distance between two bands: +/-10mm |
| Dimensions |
4 x6m: 6m minimum length, width 4m +/- 1% , with 6 bands and pre-punched holes
4 x60m: 60m minimum length, width 4m +/- 1% , with 6 bands and pre-punched holes |
| Weight, plain sheet only, excluding the bands weight |
190g/m² ± 20g under ISO 3801 (equivalent to 170g/m² minimum to 210g/m² maximum) |
| Weight, complete sheet including bands weight. |
Plain sheet specific weight plus 10% additional weight for the reinforcement bands under ISO 3801. Total weight from 187g/m² minimum and 231g/m² maximum. Specific weight of the bands from 150g/ m² minimum and 200g/m² maximum. |
| Tear strength in plain sheet at state of origin |
Minimum 100N under ISO 4674-1B 2003, with a test piece of 200x200mm as described in ISO 4674 annex B, in plain sheet. |
| Tensile strength in plain sheet at state of origin |
Minimum 500N and 15% to 35% elongation in warp and weft in plain sheet under ISO 1421-1. |
| UV resistance of the plain sheet, measured as remaining tensile strength after UV exposure |
The tarpaulin tensile strength under ISO 1421-1 after 1500 hours UV under ASTM G53/94 (UVB 313 nm peak) must be: Minimum 80% of the original value of the actual product, AND not less than 475N. To be tested in the plain sheet. |
| Tensile strength in the reinforcement bands at state of origin |
Minimum 700N inside the reinforcement bands as per ISO 1421-1, pulling lengthwise in a pre-punched hole of 8mm with a hook of 8mm wire diameter. To test in 2 holes in each side bands |
| UV resistance of the reinforcement bands measured as remaining tensile strength after UV exposure |
The reinforcement bands tensile strength under ISO 1421-1 after 1500 hours UV under ASTM G53/94 (UVB 313 nm peak) must be: Minimum 80% of the original value of the actual product, AND not less than 665N. To be tested inside the reinforcement bands as described above. |
| Welding |
Only one (01) is allowed along the middle of the sheet, length wise. The tarpaulin tensile strength crossways at the place of the welding under ISO 1421-1 must be: Minimum 50% of the original value of the actual product, AND not less than 400N. |
| Fire Retardant |
Fire retardant option available as per customer requirements |
| Opacity measured as minimum reflection and maximum transmission, in the range of visible light and near infrareds. |
Measured under ISO 13468-1. Values should be measured respectively from 350 to 750nm, and from 750 to 2500nm wavelength. The final result is the average of the averages in each range. Minimum total reflection: 35% Maximum total reflexion: 50% Maximum total transmission: 5% |
| Colour |
White sun reflective on both sides of the sheet. Grey coating on the outside of the bands. Inner black fibres to ensure opacity. White Coating colour definition:
L.a.b Coordinates under ISO 105J01
Minimum L: 82
“a” value between -1.7 and +1.5
“b” value between -4.5 and 0 |
