Materials laboratory
We provide comprehensive support in the detection and verification of material and material properties.
We test your materials and products for their properties. For this purpose, we use various destructive and non-destructive testing methods. For example, we use visual inspection, radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing, transverse tensile testing, chemical analysis, bending testing, notched bar impact testing, fracture testing, hardness testing, tensile testing, macrosection testing and microsection testing.

Test method
We carry out development-accompanying and production-accompanying testing for all sectors - and thus support our customers in several industries, including the energy sector, rail technology, automotive, aviation and shipping.
Do you have special requirements? We develop individual test procedures for you. Our extensive testing equipment in our environmental and fire laboratories enables us to support you beyond the standard specifications, meeting your individual needs. This means that we can also provide you with comprehensive and competent advice on technical innovations, innovative material compounds and information on the scope of conventional tests.
Mechanical-technological testing
We perform mechanical material tests to investigate static mechanical material properties such as strength properties and elongation behaviour. Our repertoire includes tensile tests as well as compression tests to test the tensile strength, yield strength and elongation of a material. In addition, tests such as stationary (according to Rockwell, Brinell and Vickers) and mobile hardness testing (according to the UCI method) are part of our extensive range of services. We examine the toughness of your material with notched bar impact tests. We offer these for materials with an impact energy of up to 150J and temperatures from RT to -40 °C. For welding or brazing proximity tests and the examination of your material for intergranular corrosion, we subject your sample to a bending test.
Chemical analysis
We use the emission spectroscopy method to determine the chemical composition of iron-, aluminum- and copper-based materials. Furthermore, we can determine the content of carbon and sulfur in cast iron by means of combustion.
Non-destructive material testing
RST is the right contact when it comes to non-destructive material testing (NDT for short). We offer non-destructive material testing for all common NDT methods, from X-ray testing, ultrasonic testing and magnetic particle testing to dye penetrant testing and visual inspection - stationary or mobile throughout Germany.
Damage analysis according to VDI 3822
Our accredited laboratory offers comprehensive damage analyses - for manufacturers, the insurance industry and trade alike. With systematic damage analysis based on material-technical examinations, we get to the bottom of causes of damage and material fatigue. We differentiate between misuse, assembly and material defects.
Metallographic examination
In our laboratory we offer metallographic examinations. They serve the qualitative and quantitative description of the material structure. With the help of microscopic methods, we can also identify geometric parameters of metallic materials.
By means of reflected light microscopy with digital image documentation, we can perform quantitative microstructure evaluations such as the determination of phase fractions, grain sizes, layer thickness and inclusions as well as graphite classification.
In addition, we offer stereomicroscopy with digital image documentation to perform macrosection weld evaluations, macrofractographic fracture surface examinations, and macroscopic examinations of components from the store floor.
Scanning electron microscopy
Scanning electron microscopy enables us to examine surfaces with regard to their wear, corrosion and microfractographic fracture surfaces. We distinguish between toughened, brittle fracture and enamel surfaces, among others. In the scanning electron microscope, we can perform micro-area analysis of surface layers, coatings and particles using EDX.
Testing of fasteners
Screws, nuts, washers, bolts, etc. are "fasteners" that require specific testing. We determine the strength of high-strength screws or the chemical composition of stainlessnuts.
Just what you need.
RST is your competent partner for the testing you need.
Purchasing
Our optimized processes guarantee you fast and smooth processing of your order without long wait times. Your request is our top priority. Our wealth of experience is based on countless test orders successfully completed for a wide range of customers. Our in-house test rack production as well as our in-house calibration laboratory ensure the highest flexibility and cost efficiency.
Project management
With our technical support, we are always at their side - even in the event of unexpected changes to the planned test sequence, necessary rework and adjustments to the test specimen, and under deadline. During the test, you can rely on optimal communication with our testers and engineers. We always keep you up to date and contact you quickly in case of problems or damage to the test object. You are welcome to accompany your tests personally on site or via video transmission.
Quality management
RST is available to you as an accredited laboratory. Our competent and experienced test staff, equipped with comprehensive knowledge of standards and test requirements, are prepared for any challenge. Within the framework of our flexible accreditation, we develop individual test procedures for you outside of the standard specifications and are available to advise you the entire time. We deliver high-quality test reports in German and English.
