IEC60068-2-75 Appendix D IK01 to IK06 Pendulum Impact Testing Machine
1. Introduction
The IK Pendulum
Impact Testing Machine is an impact testing device for materials such as shells or glass.
Pego make the device according to the requirements of
IEC60068-2-75, GB/T2423.55, IEC62262, and GB/T20138 standards. It
is mainly used for impact testing of non-metallic material
specimens or products such as plastics, glass, and ceramics. It is
a test instrument for evaluating the impact resistance of
materials. According to the IK impact standards IEC62262 and
GB/T20138, this test machine only contains five impact elements:
IK07, IK08, IK09, IK10 and IK11. The hammer is released manually
and the impact test sample (EUT) is dropped horizontally. This
device is often used in lighting standards for impact tests on
non-tempered glass. It mainly includes 4 hammers, a host, and
bracket casters.

4. Maintenance
4.1 The device is purely mechanical manufacturing, should keep
regular maintenance, frequent lubrication of screw and bearing
bits.
4.2 The device is strictly prohibited from no-load impact, that is,
there should be an object under the striking element
4.3 Remove the striking elements when the device is in non-working
state.
4.4 Inspect before using, make sure the apparatus placed level.
4.5 Working condition: 5~35℃ (temperature), 45~75% (R.H.)
