Method of Calibration Of Spring Impact Hammer Calibration Device

According to IEC60068-2-75 annex B.2,the principle of this calibration procedure is to compare the energy provided by a spring hammer,which is difficult to measure directly,to the energy of a pendulum,calculated from its mass and height of fall.

The spring hammer to be calibrated is put in the release base of spring impact hammer calibration device and is then operated three times by means of the release device;it shall not be released manually.

For each operation,the striking element of the spring hammer to be calibrated is turned in a different position.The average value of the three readings on the calibration device is taken to be the actual value of the impact energy of the specimen.

ZLT Spring Impact Hammer Calibration Device was sold to National Institute of Metrology China,SCM,GRGTEST,TSQ,etc.
