ISO 13937-2 紡織品的撕裂特性
這種方法主要適用於編織織物，但也可能適用於由其他技術所生產出的織物，如一些非紡織製品（與上述提及織物限制相同）。但是，這種方法並不適用於針織物及彈性織物，也不適合在撕裂測試中可能發生撕裂從一個方向轉移到另一個方向的高度向異相性織物或寬鬆織物。
將一矩形試樣剪切其較短邊的中心成褲子形。褲子的兩管分別被固定在兩個夾面間，並在織物的切割方向拉撕織物，此連續撕力是在指定距離下等速進行，而撕裂力量則由峰值所計算。我們建議使用高速智慧型測試數據記錄率記錄測試，它必須具有 100Hz 或更高的電腦傳輸速率，以擷取、記錄所有波峰和波谷。
為夾緊適合於拉伸測試系統的材料，我們採用橡膠包覆夾面的氣動式夾具。雖然手動夾具亦可操作，但由於氣動式夾具的易用性、生產效率以及具有較好的重複性，我們許多的用戶仍然較傾向使用氣動式夾具。這些夾具可設定夾緊壓力，而手動操作夾具就取決於操作者的力量（可能不那麼具重複性）。此外，我們發現，在這些測試中，夾持壓力與試樣的對齊是非常重要的。太多的夾持壓力造成過早斷裂，沒有足夠的夾持壓力反而會導致試樣在達到或接近夾面時滑脫或斷裂。這些夾具通常適用於在單柱或雙柱桌上型設計上。Bluehill® 2 測試軟體能輸入試片細節、設定所需的測試控制、自動計算出所需的結果和統計並產生所有按照標準的測試報告。
我們建議檢閱 ISO13937 - 2，以充分了解測試夾具與結果要求。
