Apparatus:

Static Materials Testing Machines:
The range of loads up to 1200 kN:
The testing machine Zwick / Roell Z1200, equipped with chamber temperature allowing for the tension or compression test at a temperature from 123 K to 873K and a laser extensometer laserXtens.
The range of loads up to 100 kN:
The testing machine INSTRON 6025 modernized by Zwick / Roell, equipped with a furnace MAYTEC allows you to perform tensile tests at temperatures up to 1473K, working with high-temperature extensometer and macro extensometer
The testing machine INSTRON 3382 capable to perform tension and compression tests, equipped with furnace for tension tests at temperatures up to 1473 K.
The load range up to 0.1 kN:
The testing machine MTS / Adamel DY30 equipped with a head measuring load up to 100 N.

Hardness tester:
Universal Hardness Testers Zwick / Roell ZHU250 and micro-hardness tester CSM Instruments.

Pendulum impact testing machines
Pendulum impact tester Zwick/Roell RKP450 that allows for impact and dynamic tension tests. For the tests at the lower temperatures the impact machine is equipped with cooler for the samples.

As part of the modernization the Laboratory was equipped with the drop weight impact tester CEAST INSTRON 9350 allowing to perform test for the energy range from 0.59 J to 757 J (not covered by the PCA accreditation).


Description of the equipment:

The laboratory has a system adapted to endurance tests for tension or compression loads of up to 1200 kN. The system provides a measurement of the load and elongation (shortening for compression tests) in accuracy class 0.5, thus providing reliability in applications such as quality control and testing of materials and products.

The Zwick/Roell Z1200, INSTRON 3382, INSTRON 6025 (modified by Zwick/Roell) and MTS/Adamel DY30 are the electromechanical machines by which the study of mechanical properties can be carried out at a constant strain rate or constant traverse speed. The data acquisition system can record the entire tensile/compression test directly on the computer in the form of a data file. Maximum load range - 1200 kN can be recorded by the load cells of the ranges 0-0.1; 0-10; 0-100 and 0-1200 kN. The accuracy of the recorded force values, for each of the ranges of force is less than 0.5% of the full scale. Traverse speed is regulated smoothly in the range of 0.001-600 mm/min.

As a standard all valus according to PN-EN ISO 6892-1:2010 (tension test) and PN-57/H-04320 (compression test) standards are determined in the tests. In addition it is allowed to change the test methods in order to adapt them to the customer's expectations or industrial needs/standards.

The Zwick/Roell Z1200 machine provides the ability to perform material tests: compression, tension and fatigue with a maximum load of 1200 kN. In addition:

 

 

The INSTRON 6025 machine modernized by Zwick/Roell has two workspaces (above and below the moving traverse) which facilitates the planning and execution of experiments. In addition:

 

The machine is also equipped with three-point bending device.

UNIVERSAL HARDNESS TESTERS Zwick / Roell ZHU250 allows to measure of hardness in Vickers, Brinell, Rockwell and Knop scales, in particular:

The Universal Hardness Testers is equipped with two lenses (magnification 45x and 90x). Measurement is possible for samples with a maximum height of 250 mm.

 

 

 

Pendulum impact tester ZWICK/ROELL RKP 450 allows to performs Charpy, Izod and dynamic tensile tests according to DIN, EN, ASTM, ISO and PN standards.

The impact tester is equipped with two rams 300, 450 J and the instrumentalized knives, which allows to measure the breaking force as a function of time or displacement in accordance with ISO and ASTM standards. In addition:

 


 

 

A view of the sample cooler

 

Drop hammer INSTRON CEAST 9350 is designed to perform impact tests using impact energy ranging from 0.59 to 757 J and the velocity in the range of 0.77 to 4.65 m/s. Hammer is equipped with high-strength frame and precise manual control. In addition:
It is equipped with a modular measuring head with interchangeable hammers.
The applied software provides the ability to control acquisition results and their analysis and reporting of research.
Used in the device acquisition system allows a high sampling rate up to 2 MHz.

 

 

 

 

 

Preparation of samples for investigation

The laboratory tests samples supplied by customers. When determining the condition of order, a customer is instructed about sample dimensions and shapes recommended by Polish Standards, and about admissible deviations of dimensions as well as the method of preparing samples for investigations.

The main factor limiting the dimensions of samples to be examined in static tensile tests is the value of loading force, which cannot exceed 100 kN for INSTRON 3382 i 6025 machines and 1200 kN for Zwick/Roell Z1200 machine. When investigations are conducted at low or high temperatures, admissible sample dimensions are additionally limited by the devices working with the testing machine i.e. the size of constant temperature zone in high-temperature furnace and the specific requirements related to mounting samples in the holders. In addition in the case of research using machine Zwick / Roell Z1200 round samples with threaded head are required.
