Geotextile gbt-2008.200g / m2 test standard value
GB / T-2008 is the national executive standard for filament woven geotextile. 200g / ㎡ of the filament woven geotextile warp rupture strength ≥ 50KN / m, zonal rupture strength of the rupture strength of 0.7-1.0 times the elongation at break ≤ 35% weft ≤ 30% , The width of the deviation of -1.0%, CBR breaking strength ≥ 4.0KN, the equivalent aperture O900.07-0.5mm, the vertical permeability coefficient (1.0 ~ 9.9) × (10 negative square ~ 10 negative five times), tear Breaking strength ≥ 0.8KN, irrigation thickness deviation of ± 8%, length and width deviation of ± 2%, sewing strength ≥ breaking strength × 50% KN / m, which irrigation thickness deviation, length and width deviation, sewing strength only on the mold Bag cloth assessment. Under the GB / T-2008 GB standard.
