Principle of calibration:
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. And it's designed with the requirements of Annex B of IEC60068-2-75.
Construction:
It's maily made of a frame, a bearing, a drag pointer, a pendulum, a release base and a release device.
Notes:
The Calibration Device fo Spring Hammer can be used for all models, allowing verification of the proper functioning of different types of hammers with the same calibration.
The spring is designed for calibrating spring hammers having characteristics as defined for energy values equal to less than 2J.
Conforms to:
IEC60335, IEC60065, IEC60745, IEC61029, IEC60601, IEC60610 etc.
