Tests for the Defence Industry

Testing of products and materials plays a key role in the defence industry, both in development and in production itself. Extremely high demands are placed on quality, reliability and safety in the defence sector. Every component, from personal equipment to sophisticated systems and technologies, must function flawlessly even in extreme conditions. Thorough testing makes it possible to verify the durability and long-term service life of individual materials and entire products, thereby helping to minimise the risk of failure in real deployment.

Temperature and climatic tests

We test the durability of equipment in extreme temperatures and demanding climatic conditions. We simulate arctic frost, tropical humidity and intense heat with rapid temperature changes. We provide both short-term and long-term tests that reveal weak points in the design and verify the reliability of the equipment in real deployment. Thanks to the wide temperature range and controlled humidity, we help manufacturers prepare their equipment for all the conditions that may arise in real operation.

Vibration tests

We verify the mechanical durability of equipment under the effect of vibrations in various axes and frequency ranges. We simulate the conditions of transport, operation and combat deployment, including random vibrations and controlled frequency sweeps. Vibration tests help to reveal design weaknesses, loosening of joints and failure of electronic components. Thanks to the precise setting of vibration intensity, we ensure that your equipment remains reliable even in the most demanding environment.

Corrosion tests

We test the resistance of materials and surface treatments to corrosion in aggressive conditions. We simulate the effects of salt fog, humid environments, condensation and combined climatic cycles. Corrosion tests help to verify the long-term service life and functionality of equipment exposed to salt, humidity and chemical substances. Thanks to the controlled course of the tests, we quickly identify weak points and contribute to greater reliability of your equipment in real deployment.

Preparation of metallographic samples

We provide professional preparation of metallographic sections from materials used in the defence industry, such as copper, steels and special alloys. We prepare the samples with an emphasis on preserving the material structure and a high surface quality for subsequent microscopic analysis. Thanks to precise grinding and polishing, it is possible to evaluate the microstructure and any defects in detail. The entire process can be supplemented with digital documentation and automated image evaluation, with an emphasis on efficiency and repeatability of results.

Hardness measurement

In our laboratory we carry out precise hardness measurement using the Rockwell, Vickers and Brinell methods on parts of weapons, ammunition and cartridge cases. These tests allow us to evaluate the correct manufacturing process and the hardness of the base material for proper functionality when firing under the demanding conditions of the defence industry. To increase efficiency and repeatability, we use automated measurement with the Impressions software, which ensures automatic evaluation of the indentations, digital documentation of the results and statistical processing of the data. This enables us to achieve high accuracy and speed while minimising the influence of the human factor.

Strength tests

We perform mechanical strength tests of materials used in arms manufacturing, including parts of weapons, ammunition and cartridge cases. We focus on tensile tests, which make it possible to determine the tensile strength, yield strength and elongation of the material. Thanks to precise control of the test conditions and digital recording of the loading process, we obtain reliable data on the behaviour of the material under mechanical stress. The results serve to verify the quality of input raw materials and finished products and to optimise manufacturing processes.

Microscopic analysis

We perform detailed microscopic analysis of metallic materials used in arms manufacturing, including copper, steels and special alloys. We focus on evaluating the microstructure, phase composition, grain size and transition zones, which affect the mechanical properties and reliability of the final products. The analysis is carried out on light microscopes with the possibility of digital recording and automated image evaluation, which ensures high accuracy, repeatability and efficient processing of results.

We'll be happy to advise you.

Tests for the defence industry

We specialise in temperature and climatic tests, thermal shocks, vibration and corrosion for the defence industry. We verify the reliability of your equipment under conditions that simulate real deployment – from scorching heat to freezing extremes, from intense humidity to aggressive corrosive environments. We test according to military standards, including MIL-STD-810 and AECTP, and we guarantee results you can rely on.

Climatic tests of military equipment

We are able to test products for the defence industry in accordance with the MIL-STD 810 standard, according to selected categories: Method 501, Method 502, Method 503 and Method 507.

Hardness of cartridge cases

We measure the hardness of cartridge-case cups using the Vickers or Rockwell method, with the possibility of automated evaluation using the Impressions software. The tests verify the correct manufacturing process, annealing and material quality.

Vibration tests of military equipment

We can carry out testing of mechanical properties in accordance with the MIL-STD 810 standard, according to selected categories Method 514 and Method 516.

Which standards we test to for you

In our laboratory we are able to test according to many international standards. MIL-STD-810 – the American military standard for testing the durability and reliability of military equipment in extreme conditions, AECTP-300 and AECTP-400 – NATO standards that provide guidance for the environmental and mechanical testing of military equipment, RTCA DO-160G – an international standard for the environmental testing of airborne aircraft equipment.

We also fulfil selected chapters of the MIL-STD-883 and MIL-STD-750/2 standards dealing with the testing of microelectronics.
