ASTM D695 硬质塑料的抗压特性
根据我们在实验室中已经进行的试验，建议使用以下设备来执行ASTM D695的压缩测试：两个安装在拉伸试验机上的直径为50毫米（2英寸）的硬化钢压缩板，我们用的是型号为2505-022的压缩夹具和一个应变测量装置，如一个25㎜(1 in)直接连接到试样的引伸计。硬质试样的测试通常需要一台应变测量设备，在这种测试中系统柔度影响测试结果。Bluehill® 3材料测试软件可以设置所需的测试控制参数，自动计算出所需的结果和统计，并生成测试报告。

The AutoX 750 is a high-resolution, long-travel automatic contacting extensometer. It can be mounted onto any electromechanical 3300, 5500, or 5900 table top and floor model systems, as well as LX, DX, HDX, and KN static hydraulic testing systems. It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more. The AutoX has a maximum travel of 750 mm and accuracy of ± 1 µm.

The 2630-100 series of extensometers offers speed of attachment and ease-of-use. The light-weight, rugged cross-brace design eliminates errors caused by physical distortion, while built-in protection ensures that damage is not caused by over-extension. The low operating-force arms of the extensometer reduce the possibility of knife-edge slippage when testing hard or smooth surfaced materials.
