FP 573 2.0109 HIT Pendulum Impact Testers from 5 to 50 Joule Intelligent Testing

1. The Pendulum Impact Testers from Zwick are a HIT Important Characteristics Leading mechanical testing products manufacturer Zwick Roell Group’s HIT Pendulum Impact Testers are benchmark instruments for plastics manufacturers and processors Accuracy, dependability and ergonomic design are primary features of the HIT pendulum impact testers. Advanced manufacturing technology brings improved accuracy specifications, with the following innovations and benefits for users in both R+D and quality assurance: • Pendulum coding as standard The HIT Pendulum Impact Testers automatically recognize...

2. HIT Pendulum Impact Testers – Everything a Pendulum Impact Tester Needs Low vibration instrument design The systematic design of the perfect low-vibration pendulum impact tester begins with the items closest to the specimen - the pendulum and the supports. Models available HIT pendulum impact testers are available in two versions: • Stand Alone model This model is the ideal choice when there is no need to store test data. The results are calculated by the pendulum impact tester and can be displayed as required as absorbed impact energy, or as a percentage of the pendulum´s potential...

These outstanding features earned HIT pendulum impact testers the Materialica 2006 Design Award. The heavy frame is made of cast iron to dampen vibrations, and three heavy-duty locking leveling-feet ensure that the HIT remains perfectly level. Motorised pendulum return After the test the pendulum is automatically captured and returned to the starting position. This feature enables the starting angle setting to be varied and optimum test parameters such as impact speed and energy loss on impact to be determined. Pendulum identification and interchangeability Just as a certified weight has...

Instrumentation Modern instrument electronics With instrumented testing, the load during impact is measured using piezo load cells or strain gages, depending on the individual case. The raw values are in the form of a load-time curve. The electronics perform all important functions: the calculation and display of impact energy, the standardcompliant correction of windage and bearing friction and monitoring the vertical position in the impact direction. Filtered force in N PC connection except with the Stand Alone model, is via a USB interface. There is also a serial interface for connection...

Specimen conditioning A magazine and tempering box are available from Zwick. The pendulum is easily changed by means of a quick release mechanism, eliminating the need for tools. The optional safety protection system incorporates an integral collecting tray on the left side for specimen remains and can be emptied by swivelling the shield out. The electronics feature a simple and easy-to-use keyboard, with a large, clear display designed to reduce fatigue even when testing large batches. The structured menu system makes operating the instrument quick and easy. Application range and standards...

A local operator shield is available for the Charpy fixture to protect the operator from flying debris (Fig. 3) In the interests of safety the HIT25P and HIT50P are equipped for two-handed operation and have safety devices to left and right. testXpert® II PC-Software A choice of Master and Standard Test Programs are available for the HIT pendulum impact testers. Master Test Programs have a comprehensive range of options and flexibility to control test parameters and process results, and are perfectly suited to research and development needs. Standard Test Programs are focused on individual...

The quick change adapter plates are used to adapt the pendulum impact tester to different specimen widths, whilst the supports are precisely positioned using set pins and adapt to the specimen thickness. An optional swivelling protective shield can be used with the fixture, and a positioning aid helps to locate the specimen correctly, using either the notch or the front edge of the specimen. Advantages: • Quick changing of Charpy fixture • Anvils precision-made by CNC machine and individually inspected for 100% accuracy Izod fixture Two types of Izod fixtures can be used: The manual fixture...

For tests according to ISO 8256, Method A one specimen shoulder is gripped a yoke. The other end of the specimen is clamped in the tensile impact fixture. The pendulum strikes the yoke and creates a tensile impact on the free end of the specimen. Yokes with masses of 15 up to 120 g are available. Dynstat fixture The HIT pendulum impact testers can also be equipped for Dynstat tests to DIN 51230. A Dynstat fixture and a comprehensive range of pendulums cover the Dynstat applications. For tests according to ISO 8256 Method B and ASTM D 1822, one specimen end is gripped in the pendulum. The...

3. Instrument Specification HIT5P The specification guide on the following pages is designed to help you to configure your instrument to meet your testing requirements. Naturally, we will be happy to answer any questions that may arise. The following points should be checked before a pendulum impact tester is specified in detail: • To be used with or without a PC • Standards to be used • Test methods and specimen to be used For a quick orientation we marked the item numbers with a red dot (•). Selection of the basic instrument HIT5P Max. impact energy Impact velocity Width x Height x Depth...
