HF-8811 電線加熱變形試驗機
PARALLEL PLATE PLASTOMETER
JIS-C-3005 

試料本機一定溫度中，加熱 30 分鐘后，夾在本機平行板間，加規(guī)定之荷重，于同溫下再經(jīng) 30 分鐘，然后以加熱前后之厚度差，除以加熱前厚度，以百分比為單位，即為變形率。
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。
