Pendulum Impact Tester RKP 450 Zwick

Pendulum Impact Tester RKP 450 Zwick

Range of Application

  • Impact and impact bending tests on metals (Charpy, Izod – conventional and instrumented)
  • Brugger -Method tests to ensure the wear characteristics of toothed gear wheels
  • Wedge -impact test to determine the strength characteristics of structural adhesives An operationally ready instrument includes:
  • Basic instrument, with electro-magnetic pendulum release and motorized pendulum return, grout and heavy duty screw anchors, electrically monitored safety device and safety housing
  • Steel armament or concrete base
  • Test specific accessories such as vises, supports and anvils, pendulums and fins
  • Optional accessories such as PC equipment or specimen temperature units

Installation

According to international Standards, the base frame should be firmly anchored to the floor. This is done either with

  • A steel reinforcement for the The making of the foundation is performed by the customer.
  • Or with a readymade concrete foundation with

40 times the mass of the largest pendulum, incorporating steel reinforcement. The foundation is equipped with metal lugs for bolting to a solid cement floor.

Please pay attention to the remarks in PI 476.

Product Description

Feature & Advantage:
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.
Safety device
Zwick pendulum impact testers in size category RKP450 satisfy the EC Machinery Directive 2006/42/EC, the EN ISO 12100 as well as the EN ISO 13849-1/2. 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 safety device fully complies with the requirements of national and international standards. Important characteristics and functions of the safety
device:
• It is equipped with a double safety protection system using twin, certified, independently operating control units, special safety switches and components.
• It monitors the pendulum impact tester according to its operational mode (e.g. test or setup mode)
• It recognises incorrect operation and displays this with blinking signals on the operating keys
• 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.
Safety housing
The design of the safety housing facilitates easy handling during the testing process, changing tools, pendulums or fixtures, re-configuring different test types and maintenance and calibration. Operating components are centralized and illuminated to show the machine status and error messages, making the RKP450 safe, simple and fast. Front door, side doors and specimen removal slot allow:
• Simple placement of the specimen
• Quick changing of the vise and the pendulum
• Easy access during maintenance, inspection and calibration
• Easy removal of specimen remains
