スポンジ繰り返し圧縮寿命試験機

スポンジ繰り返し圧縮寿命試験機

U知っている :

The machine is used to test the permanent deformation rate of foamed plastics.

According to the standard ISO 7214, JIS K6767, K6382: the thickness of the test piece was accurately measured. As for the compression plate of the testing machine, the specimen was compressed at a height of 50% at a frequency of 60 times per minute, and reciprocated compression reached 80,000 タイムズ. After being placed at room temperature for 30 分, the thickness was measured and converted into compression deformation rate.
