遵照 ISO 179-2 以儀器化衝擊測量 Charpy 衝擊性能
ISO 179-2 要求塑膠試樣在三點彎曲配置情況下進行衝擊，並計算試樣破斷時的衝擊強度。如果使用儀器化衝擊測試機，就可以透過力/撓度或者力/時間曲線更好的觀察材料在衝擊過程中的細節特性。有示波衝擊頭的擺錘系統就可以測量試樣在整個衝擊過程（錘頭與試樣接觸到試樣破裂）中許多非示波無法測量/計算的能量值。根據不同的測試材料或者不同的缺口類型需要訂定不同的測試參數。儘管 ASTM D6110 也是 Charpy 塑膠缺口衝擊測試標準，但由於定義的測試參數不同因此不能替代。
為執行 ISO 179-2 標準之規定，建議使用我們的 CEAST 9050 擺錘——手動或電動版本，包含試樣的夾持虎鉗、適當大小的肩狀物、錘、DAS（資料擷取系統）和 Visual-Impact 套裝軟體等。此外還有低溫控制系統，可以進行低溫衝擊測試，測量試樣在低溫條件下的衝擊特性。
對於正確的試樣製備，我們建議使用Motorized Notchvis 或搭配缺口刀的自動缺口機，以滿足標準所需的缺口。
我們建議您檢閱測試標準，充分認識測試設置、程序、結果的要求以及試樣製備要求。
CEAST 9000 Series Pendulum Impact Series
Impact resilience is one of the most important properties and cost-effective evaluations for material producers, both with respect to product development and quality control. As components could fail at stress levels well below the critical fracture stress, accurate determination of impact damage propagation is necessary. With the combined experience of CEAST, Instron® has more than 50 years experience in designing pendulum impact testing systems.

CEAST Data Acquisition and Analysis
The new CEAST DAS 64K is a state-of-the-art Data Acquisition System designed for impact testing instruments. Compatible with the full range of CEAST impact testing systems, including pendulum type machines (CEAST 9000 Series) and drop towers (CEAST 9300 Series), it’s the key for instrumented impact testing. The DAS 64K also enables the data collection from instrumented tups or hammers on older models and non-CEAST impact machines.
