Industrial Plastic Components, Adhesive Bondings & Coatings

Material testing of rail vehicles

Rail vehicle industry

For the rail vehicle industry, we can provide a broad testing portfolio with our interdisciplinary technical center: We test individual plastics and components for interior and exterior use as well as coatings and adhesive bonds. Fire and corrosion tests are just as much a part of our services as weathering and climate tests or testing the color fastness and resistance of components, surfaces, adhesives and coatings in conjunction with chemicals.

Our tests

Testing of materials in rail vehicles
- Testing of coatings, adhesive joints, plastics and components for indoor and outdoor use
- Testing of bonded joints according to various regulations (e.g. DVS 1618, DIN 6701 etc.)
- Design (calculation) of bonded joints
- Selection and optimization of adhesives
Coating tests
- Determination of complex layer structures
- Adhesion tests
- Optical properties (e.g. color, color difference, gloss, surface roughness)
- Mechanical properties (e.g. hardness, scratch resistance, abrasion, resistance to e.g. stone impact, hail impact)
Artificial weathering and climatic tests
- Sun simulation test DIN 75220
- by means of xenon lamps, e.g. “Kalahari” and “Florida Test
- Climate change tests on materials, products and components in the range -70°C to +150°C on component dimensions up to (4000x2400x2000)mm
Fire tests
- EN 45545-2: European requirements for burning behavior of railroad applications: Smoke density (smoke chamber according to EN ISO 5659-2), smoke toxicity
- DIN 5510-2: German fire protection requirements in rail vehicles
- NF F 16-101: French fire protection requirements; classes I and F

Corrosion tests such as neutral salt spray test (EN ISO 9227) and condensation water test (EN ISO 6270-1, EN ISO 6270-2) as well as cyclic loads (VDA alternating test)
Testing the resistance of components, surfaces, adhesives and coatings to chemicals
Testing the color fastness of coatings and components according to EN ISO 105-X12
Stone impact test (e.g. EN ISO 20567)
Verification of conformity with product specifications and standards
Customized R&D projects in the areas of bonding and coating
