Spring Hammer Calibration Device:
Model ZLT-CD:
For testing and calibrating spring-operated impact hammer, in accordance with IEC60068-2-75/1997-08 Annex B, Figure B. 1 to B. 4 with scale for impact energies from 0.2J to 1J, 2J.
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.
Standard Outfit:
1 Pendulum with rigidly clamped spring at the lower end,
1 frame with bearing for the pendulum,
1 scale plate with drag pointer, scale of anodized alumininum,
2 release bases at the frame,
1 base plate with removable release device.
· Impact energy: Max. 2J.
· Pendulum: Steel.
· Diameter pendulum: 20mm.
· Length pendulum 635mm ± 2.5mm.
· Pendulum H: 120mm ± 2mm.
· Pendulum D: 20mm ± 0. 5mm.
· Pendulum W: 4mm ± 0.01mm.
· Release device: AC. Mechanic.
