9、水平校准机构一组
五、试验步骤:
将调节后的试样水平置于回弹仪的测试位置上,通过调节使钢球底部从固定位置到泡沫塑料表面的落下高度为460mm。在释放装置上固定钢球,然后使钢球自由落下。对每一个试样做三次回弹,取三次回弹中的zui大值。每次回弹钢球应落在试样表面的同一位置上,并且两次回弹的时间间隔应控制在20s之内。如果钢球在回弹过程中碰到或弹出测量装置,所得数据无效,需重新补做。

五、试验步骤:
Five, the test procedure:
将调节后的试样水平置于回弹仪的测试位置上,通过调节使钢球底部从固定位置到泡沫塑料表面的落下高度为460mm。在释放装置上固定钢球,然后使钢球自由落下。对每一个试样做三次回弹,取三次回弹中的zui大值。每次回弹钢球应落在试样表面的同一位置上,并且两次回弹的时间间隔应控制在20s之内。如果钢球在回弹过程中碰到或弹出测量装置,所得数据无效,需重新补做。
Will test the position of the sample placed horizontally on the rebound instrument adjusted by adjusting the ball on the bottom, from a fixed position to the foam surface fall height of 460mm. Fixed ball in releasing device, and then the ball free fall. Do three rebound on every sample, a maximum value of three rebound. Each time the rebound ball should be in the same position on the sample surface, and the two rebound time interval should be controlled within 20s. If the ball on the rebound process encountered or pop-up measuring device, the data is invalid, need to do.
