ISO 2062 紗線捲裝的單端斷裂力和斷裂伸長率
ISO 2062 適用於確認紡織紗線和麻線，其斷裂力與給定位移率的斷裂伸長率。測試紗線的原料與製作過程是必要的，此過程決定了原料的品質，並用於控制最終產品的品質。
原則上，試樣是在固定的鉗口夾緊與支撐。紗線試樣會以恆定速率延伸直到破裂，其斷裂力與斷裂伸長率都會記錄。為了記錄測試，高速智慧型測試數據記錄速率是必要的，需要至少 100 Hz 或以上的速率傳輸至電腦，以擷取和記錄所有的資料。
我們選用特別設計的 2714 系列氣動線和紗的拉伸夾具，表面拋光和特定輪廓的絞盤，提供逐步增加的夾持力。這樣可以減少試樣過早失效的機會。選擇這些夾具在拉伸測試機夾緊紡織線和紗材料上是十分理想的，且通常是單柱或雙柱桌上型設計。
Bluehill® 2 軟體用來輸入試樣細節，設定所需測試控制，自動計算出所需的結果和統計資料，並依據規格產生測試報告。對於這些類型的測試，我們使用一個預張空氣控制套件，當到達預定負載或 Bluehill 預荷功能時，就會夾緊一邊夾具，以解決測試前把試樣裝入夾具時的鬆弛問題。
我們建議檢閱 ISO 2062，以充分瞭解測試夾具和結果的需求。
2714 Series Pneumatic Cord and Yarn Grips (2714-005)
Pneumatic cord and yarn grips provide a convenient method for clamping fiber, cord, yarns and fine wires to reduce the problem associated with testing these materials. A specially designed horn with a smooth finish and a contoured surface with a graduated cam allows for easy loading and a stress reduced clamping area on the specimen. The clamping mechanism can be activated either automatically or through a foot switch. This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading. Pneumatic cord and yarn grips provide selectable clamping force to accommodate different materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep.
