BOSTD Geosynthetics Qingdao Ltd. Suite D-7A, Majestic Garden No 6 Middle of Beisihuan Road Beijing 129, China November 4, 215 Attention: To whom it may concern Subject: Certification that the resin formulation for E GRID RX12 is identical to the resin formulation for Terragrid (E GRID) RX11 To whom it may concern: By this letter, BOSTD Geosynthetics Qingdao Ltd. certifies that the resin formulation and amount carbon black added to produce E GRID RX11 and RX12 geogrids is identical to the resin formulation and amount of carbon black added to produce Terragrid (E GRID) RX11 (Product also produced by BOSTD and tested for UV durability per ASTM D4355 - See Results included with E GRID RX11 Submittal) and has not changed since the date of the ASTM D4355 test provided. Therefore, it is reasonable to conclude that E GRID RX11 and RX12 will exhibit equivalent UV resistance when tested in accordance ASTM D4355. Sincerely, BOSTD Geosynthetics Qingdao Ltd.
