The pendulum impact tester PSd 750 with a working capacity of up to 750 J is applied for:
The pendulum impact tester PSd 450 with a working capacity of 150, 300 or 450 J is applied for the following tests:
The pendulum impact tester PSd 50-M with a working capacity of 50 J is especially applied for notched-bar impact tests according to technical conditions of standard GOST 10708 in connection with standard GOST R ISO 148-1 as well as applying corresponding special accessories according to notched-bar impact tests based on Charpy on metal according to standard GOST 9454.
300 J hammer with striker Charpy
For Charpy impact tests, the test specimen is placed against two anvil inserts on two supports. The striker of the pendulum hammer hits the centre of the side of the test specimen which is opposite to the notch and thus breaks the specimen. The impact energy absorbed by the test specimen is measured digitally and displayed. Dividing this energy by the original cross section of the test specimen, the notch-impact strength is the result.
Instrumented Izod striker
For the Izod impact bending test, the test specimen, which is held vertically, is ruptured as a result of the impact against the notched bar or its opposite side, while the notch root lies at the same level as the upper surface of the support. In this respect, the striker hits the test specimen at a defined distance from the notch. The notch-impact strength is calculated by dividing the absorbed impact energy by the original cross section of the test specimen at the notch.
The tensile-impact test is a tensile test with high shear rate. In this test, the energy absorbed up to the rupturing of the test specimen and the residual elongation at the break are measured. In this regard, the holder permanently connected to the anvil block is aligned the way that the pendulum hammer hits the cross yoke located at the end of the horizontally held test specimen with a striking fork when passing through the normal position. The tensile-impact strength is the impact energy absorbed by the test specimen in relation to the specimen’s smallest cross section prior to the test.
Instrumented Brugger striker
For the test based on Brugger, a specimen especially manufactured for this test is clamped the way that the contact surface of the striker meets the wide surface of the specimen fin at an angle of 30°. Mounting of the specimen must be such that during testing there is a linear contact between the upper edge of the fin and the contact face of the striker. Precaution must be taken to ensure that the shaft of the specimen can neither turn nor move in any other way during testing. The impact bending specimen is tested with an instrumented striker.
