ASTM D5587 梯形法織物撕裂強度
本標準主要適用於大多數機織紡織品，但也可適用於其他技術生產的織物。該方法規定了使用梯形法測定紡織品 撕裂力 的程序。矩形試樣經過標記和準備，以便能以一定角度裝載到夾具夾面上，使撕裂沿試樣傳播。
對於此測試，提高測試資料速率以確保擷取大量資料點非常重要。這是因為當織物中的單個纖維斷裂時，資料速率必須足夠快才能捕捉到這些峰值。
帶橡膠塗層夾爪面的 氣動側動夾具 非常適合夾持梯形試樣。雖然手動夾具也能使用，但許多人更喜歡氣動側動夾具，因為它們易於使用、生產力更高且重複性更好。可調式夾持壓力也允許使用者微調夾持壓力，以避免夾爪斷裂或滑動。
依此標準進行測試的挑戰包括：
- 快速資料擷取速率
- 試樣夾持
Instron 的解決方案：
- Instron 5900 控制器提供的快速資料擷取速率，允許以每秒高達 2,500 點的速度準確捕捉資料峰值和谷值。
- Instron 帶橡膠面的 氣動側動夾具 非常適合夾持此測試中幾乎所有類型的織物試樣，同時保持高產量。
務必查閱 ASTM D5587-15，以充分了解測試設置、程序和結果要求。
