compressive hardness 在规定条件下，使海绵橡胶达到一定压缩量所需的力，以牛顿(N)计。 测定海绵橡胶硬度时，所用硬度计的压头是圆平状的，直径有150mm，200mm，305mm等几种，压入度为试样原始厚度的40％。
方法：测定材料的硬度、压缩强度、径向拉伸强度。
Methods: The surface hardness, compress strength, diametral tensile strength of composites were measured.
经过压缩变形后，试样硬度明显提高。
Subjected to the compression deformation, the hardness of the alloy increases significantly.
公司建立了集高低温、拉伸压缩、燃烧、硬度、色差等多项实验和检测的多功能实验室。
The company has established a multi-functional laboratory, where many experiment and test can be carried on, such as, low temperature, stretch, combustion, hardness and color difference, etc.
