IMPACT

pendulum impact tester 150 / 300 / 450 / 600 / 750 Joule

optionally with instrumentation

SCHÜTZ+LICHT Prüftechnik GmbH www.schuetz-licht.de

The pendulum IMPACT tester series are designed for the highly efficient performance of notched bar impact tests and impact bending tests according to CHARPY or IZOD. Due to the rigid

machine bodies optimized for low resonances, the unaffected impact energy is reliably available

for the test and thus enables tests to be performed in accordance with EN ISO 148, ASTM E23

and all international standards.

The machines are optimized for fast test execution on metal specimens as, for example: The motorized hammer lifting only takes approx. 3 - 9 seconds (depending on the impact energy

consumed in the previous test). The machines should be placed on a machine foundation height

> 30 cm. Due to this ergonomic positioning it is then possible to carry out up to 240 tests / hour.

Even deep-cooled samples can be placed on the support and struck within a very short time (< 5

seconds) through the large safety door. The machine is optionally equipped with a sample

centring device so that the samples can be placed safely without the use of loading tongs

(exception: frozen samples).

Innovative mechanical, ergonomic and electrical equipment details make the machines the first

choice in this category. The excellent price/performance ratio and high precision are the decisive

reasons for the steel industry, universities, and companies in the automotive and aviation sectors, service providers, research and development to trust these products.

Main advantages of the pendulum IMPACT testers

• Electronic control panel for easy setting of: Test method (Charpy /

Izod), used standard (EN, ASTM, JIS ...), nominal energy (change of

weight masses), potential / consumed energy, sample data, test

temperature, date + time

• The test results can be read out via the USB/LAN interface for further

processing in the optional WIN-IMPACT software, evaluated, printed

and archived

• The exact angular position of the trigger angle and the evaluation of

the impact energy consumed are determined by means of a high-

resolution incremental rotary encoder. The high resolution ensures

the high-precision evaluation of the absorbed energy

• The operator can easily activate the automatic hammer lift (standard

setting) in the operator menu. The hammer lift uses the residual

energy available after the previous attempt to quickly raise the

pendulum again by closing an electro-mechanical clutch at right time

• The automatic pendulum hammer lift ensures that the pendulum

hammer is ready for the next test in a few seconds

• The pendulum hammer can be manually moved to any position for

changing the weight masses, the impact fin or for calibration

• The pendulum hammer can be equipped with conventional impact

fins (Charpy, Izod, impact pulling devices) or other tools that can be

changed quickly and easily

• The machine was specially designed for absolutely hazard-free use.

Among other things, safety devices are used here that have not been

implemented by any other supplier to date (swivel safety rod). Due to

the protective housing and the electrical locking of the safety door,

simple and fast operation from the outside is possible

• 24 months warranty

• Unbeatable quality-price-ratio

• Power connection only 220 / 230 V required

• Delivery includes DAkkS calibration by SCHÜTZ + LICHT Prüftechnik

Options • 2 types of centring devices: A.) swivelling in from below B.) with extending lateral stop

• Loading tongs for handling cooled samples, with centring function (centring device may not be required)

• Deep cooling cryostat: Bath for notched bar impact bending samples down to - 90° C (special brochure)

• Stainless steel funnel plates with conveyor belt: Broken samples are directed funnel-like onto the conveyor belt

(recommended if the lateral expansion of the samples must be measured / the samples are sorted

• Side parts protective housing hinged and locked one side / both sides

• Application of the hammer fin for instrumented notched bar impact tests with special electronics / software

• Notch broaching machine for the rational insertion of the notch into a prefabricated sample 55 x 10 x 10 mm

IMPACT




Option: Equipment for instrumented notched bar impact test

Principle of operation In this type of impact test, the fin of the pendulum hammer is designed

as a load cell. During the test, the abruptly increasing force is recorded by means of this force measuring

device by a transient recorder (high-speed recorder) and displayed and evaluated in software as a force

/ displacement (force / time) diagram.

With successive numerical derived functions, a diagram force / displacement (force / time) as well as the

resulting work (area under the curve) and an indication of how the specimen sells (increase the

information about the test).

Software This software is a version of

the LabTest testing software that has been

reduced to the essential. It has been freed

of all unnecessary functions - but is one of

the core components of the system.

Samples The test recording is done by a

special high-speed measuring system - a

transient recorder. This recorder plots the

measured values in the instrument's

internal memory. After the test, these are

output directly to the PC software and

evaluated. The PC connection is via USB

interface.

Schematic representation of the measuring technique

Conformity to standards: UNI EN ISO 14556 (2003)

The instrumentation of the impact fin is available for both types of

available impact fins:

• ISO148 - radius 2 mm

• Type ASTM - radius 8 mm

The impact fins are for pendulum hammers with potential energy

from 150 | 300 | 450 | 750 joules available

If this system is retrofitted, a new calibration is necessary because the

mechanical components are changed: cable, photocell.

The software WIN-IMPACT and WIN-IMPACT-Instrumented can be used in

parallel, with the proviso that faults may occur occasionally.

The test curve can be exported in Excel format to perform external

calculations.

Results / Reports The system automatically evaluates all important

results according to the standard. In view of the great

variability of the deformation curves, the user was

enabled to move the evaluation algorithms / query

points to perform individual evaluations.
