ISO 179-2 仪器化夏比冲击试验方法
ISO 179-2要求塑料试样在三点支撑情况下进行冲击，并计算试样破断时的耐冲击值。如果使用仪器化冲击试验机，就可以通过力/挠度或者力/时间曲线更好的观察材料在冲击过程中的细节特性。有示波冲击头的摆锤系统就可以测量试样在整个冲击过程（锤头与试样接触到试样破裂）中许多非示波无法测量/计算的能量值。根据不同的测试材料或者不同的缺口类型需要制定不同的测试参数。尽管ASTM D6110也是夏比塑料缺口冲击试验标准,但由于定义的测试参数不同因此没有可替代性。
为执行ISO 179-2标准之规定,我们推荐英斯特朗CEAST 9050摆锤冲击系统。它有手动/全自动两个系列，有以下部件可供选择：试样支撑制具、不同尺寸的安全保护罩、示波冲击头、DAS（数据采集系统）和Visual-Impact软件包等。此外还有低温控制系统，可以进行低温冲击试验，测量试样在低温条件下的冲击特性。
缺口试样的准备；我们推荐英斯特朗CEAST的电动缺口制样机，当然还有全自动型号可供选择。同时供应符合标准的各种类型金属开缺口刃具。
我们建议客户熟读标准，以免疏忽测试所需的要素：方法的建立、操作的流程、结果的选择及试样的制备等。
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.
