ASTM D5035 紡織物之斷裂強度與伸長量-截片法

要定義紡織物的斷裂力量與伸長量，我們為了織布使用拆開式條子織物強度試驗，為了不織布，連結的，與塗層織物使用條狀切割測試。

拆開式條子織物強度試驗試片通常寬度只有 25 mm, 35 mm, 50 mm, 或 65 mm( 加上更寬的 20 股紗 ) 而長度至少 150 mm ，我們從各種寬度移除相同數目的紗線 ( 或各 10 股紗 ) 來得到 25 mm 或 50 mm 測試寬度，也就是“拆開式”條子織物強度試驗的條件 ( 在各種必然的情況下有提供各種不同尺寸的試片 ) 。而切割測試使用的是寬 25 mm 或 50 mm 而長度至少 150 mm 的試片。

我們夾持試片的距離為 75 mm (3 in) 且使用拉伸速率為 300 mm/min (12 in/min) 將板調拉出直到斷裂，此斷裂力量與表面的伸長量之測試結果和這些測試模式是相應的。

當手動式夾置具加上平滑夾面可以運作時，許多我們的客戶比較喜歡氣動式夾置具的簡易使用，生產力及較好的重複性，氣動式夾置具可以讓你設定夾持壓力，而手動式夾置具則端看操作員的強度 ( 也許不會有重複性 ) 。我們建議選擇至少比測試試片寬 10 mm ，高 25 mm 的夾面。

我們發現夾持壓力和試片的對位在此測試中是非常重要的，太大的夾持壓力會造成過早的破壞，而太小的夾持壓力則會導致試片滑移或在靠近顎部的地方斷裂，材料測試軟體對這些測試將會有很大的幫助，因為它可以在測試開始時校正夾具夾緊或鬆弛的預壓力或預拉伸。
