Zwick Materials Testing Zw/ck / RoellProduct Information Pendulum Impact Tester PSW 750 PI 474 2.0616 Range of application The PSW 750 is used for Charpy impact tests and for tensile impact tests on metals. Impact tests to Charpy can be performed as conventional and instrumented tests. Test standards: ISO 148-1, ISO 14556, ASTM E 23, JIS Z 2242, GOST 9454-78, DIN 50115 (withdrawn). An operationally ready instrument includes: • Basic instrument without pendulum, with electro-magnetic pendulum release and motorized pendulum return, grout and heavy duty screw anchors, electrically monitored safety device and safety housing • Test specific accessories such as vises, supports and anvils, pendulums, fins • 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. Safety device Zwick pendulum impact testers in size category PSW 750 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. 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 PSW 750 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

Product Information Pendulum Impact Tester PSW 750 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...

Zwick Materials Testing Zw/ck / RoellProduct Information Pendulum Impact Tester PSW 750 Remarks on installation/requirements • Horizontal loading of the foundation during tests is extremely low. Thus correctly constructed foundations don’t need any additional measures to be taken for absorbing horizontal forces. • The bottom face of the concrete base must be in full contact with the ground to ensure that the pendulum impact tester operates correctly. • The concrete base must be bolted firmly to the ground. The fixing bolts and heavy duty dowels (M20 x 130 mm) guarantee secure fixing. They...
