Product Information
Pendulum Impact Tester RKP 450
Range of application
•t Impact and impact bending tests on metals (Charpy,
Izod – conventional and instrumented)
•t BruggerMethod tests to ensure the wear
characteristics of toothed gear wheels
•t Wedgeimpact test to determine the strength
characteristics of structural adhesives
An operationally ready instrument includes:
•t Basic instrument, with electromagnetic pendulum
release and motorized pendulum return, grout and
heavy duty screw anchors, electrically monitored
protection units and protection housing
•t Steel armament or concrete base
•t Test specific accessories such as vises, supports
and abutments, pendulums and fins
•t Optional accessories such as PC equipment or
specimen temperature units

Basic instrument
The basic instrument is designed to be mechanically
stiff and is made of vibration damping cast iron. It is
leveled on the foundation with the aid of three leveling
planes, then casted with the grout and anchored with
four bolts.
Protection unit
High capacity Pendulum Impact Testers such as the
RKP 450, must fulfil the safety requirements of
EN 9541, category 3. This means that the failure of
a single safety monitoring element must not pose any
risk to the operator. As a result, the RKP 450 has been
updated in this area, and the protection unit fully com
plies with the requirements of national and international
standards.
Important characteristics and functions of the protection
unit:
•t It is equipped with a double safety protection system
using twin, certified, independently operating control
units, special safety switches and components.
•t It monitors the pendulum impact tester according to
its operational mode (e.g. test or setup mode)
•t It recognises incorrect operation and displays this
with blinking signals on the operating keys
•t It allows the pendulum to be released via a push
button integrated into the door handle. The test can
then be started immediately after closing the safety
door. This is important for tests according to ISO
148 and ASTM E 23 on temperature conditioned
specimens, which must be tested less than 5
seconds after removing them from the temperature
unit.
Protection housing
The design of the protection housing facilitates easy
handling during the testing process, changing tools,
pendulums or fixtures, reconfiguring different test types
and maintenance and calibration. Operating compon
ents are centralized and illuminated to show the ma
chine status and error messages, making the RKP450
safe, simple and fast. Front door, side doors and speci
men removal slot allow:
•t Simple placement of the specimen
•t Quick changing of the vise and the pendulum
•t Easy access during maintenance, inspection and
calibration
•t Easy removal of specimen remains
