HF-8811 电线加热变形试验机
PARALLEL PLATE PLASTOMETER
JIS-C-3005 

试料本机一定温度中，加热 30 分钟后，夹在本机平行板间，加规定之荷重，于同温下再经 30 分钟，然后以加热前后之厚度差，除以加热前厚度，以百分比为单位，即为变形率。
This machine is used for the heat deformation test of power cords。Put specimen into test chamber of this machine under a certain temperature for 30 minutes，then clamp specimen between two parallel plates，the upper plates being subject to a constant load under the same temperature for 30 minutes。Afterwards，the differential thickness before / after heating is
divided by the thickness before heating and multiplied by % for being unit，that is deformation。
