UNHCR UNICEF approved Tarpaulin 4 X 5 M
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 5 millimeters diameter PE or PP rope on the edge, inside the hem. 1000 denier minimum.
the finished size of each sheet is 4 x 5 meters +/- 1 %.
minimum 190 gr/m2 +/-20g/m2.
minimum 600 N both directions of warp and weft (BS 2576, 50 mm grab test, or equivalent).
minimum 100 N both directions (BS 4303 wing tear or equivalent) or under ISO 4674 (A2).
stabilized against ultraviolet rays and excess heat for long outdoor exposure. Maximum 5% loss on original tensile strength under ISO 1421 after 1500 hours UV under ASTM G53/94 (UVB 313 nm peak).
Only one (01) is allowed along the middle of the sheet, length wise. Minimum resistance is 80 % of the original tarpaulin tensile strength in the weft under ISO 1421 plus additional procedure.
Provided with aluminum eyelets or equivalent on four sheet sides of the single sheets at 100 cm +/-5cm centre to centre, providing very strong fixation points.
white sun reflective on both sides. Inner black fibers to ensure opacity.
