Pressure tests of pipes and piping systems, tightness and strength of joints

These are carried out in accordance with the valid STN, EN standards in order to detect tightness, exclusion of fault sections and the possibility of using existing distributions. Only a tight piping network performs its function without environmental burden.

Impact resistance and impact toughness

In a mechanical system, impact is a great force developed in a short period of time when two or more bodies collide. Impact tests are carried out to determine the toughness of the material. In general, impact tests are carried out in two ways: Charpy impact test and Izod impact test.

The residual fracture energy of the material refers to its ability to absorb energy during deformation.

Tensile properties

The tensile characteristics of a material are its most basic mechanical characteristics. If the test body is subjected to a single-axis tensile stress, deformation or elongation is possible depending on the normal tension which may be monitored by means of a deformation curve which provides important information on the properties of the material. This addiction is determined experimentally. The test body is attached to the jaws of the test machine and a meter is attached to the body. During the test, the dependence of the applied force (F) or tension (measured by a dynamometer) on the relative elongation of the test sample (scanned by a flowmeter) is recorded.

Oxidation-induction time

Oxidation-induction time or OIT is a standardized test carried out in the DSC, which measures the level of thermal stabilization of the test material. The time between melting and the beginning of decomposition under isothermal conditions is measured. This test is common for assessing the quality of organic materials or polymers.
