Your benefits from cleanliness testing at DEKRA

  • Comprehensive residual dirt determination and analysis of particles and oil films
  • LABS tests of materials, components, products and equipment
  • Accredited laboratory analysis and testing according to all common customer specifications and test procedures
  • Fast, safe and reliable test results with meaningful reports

Particularly in the automotive industry, as well as in medical technology, aviation and the electrical industry, expectations regarding the quality and functionality of components are high. It is therefore important to avoid any possible contamination in production and processing procedures. For example, silicones, solvents and other critical substances can cause coating defects in the painting process or damage to components due to contamination. For cleanliness testing of components, precision parts and filters, we offer comprehensive residual contamination testing and determination of your component samples in our accredited laboratory in Stuttgart according to your individual requirements and on the basis of internationally recognized standards such as VDA 19 and ISO 16232. We also perform LABS tests in accordance with VDMA 24364 to assess the LABS conformity of your products, parts and components for painting systems.

In the car interior, emitting substances can negatively impact the air quality and thus may pose a health risk. They occur as volatile organic compounds (VOCs), for example from plastics of interior parts or components.In our DIN EN ISO/IEC 17025 accredited laboratory our experts use test chamber and odour measurements as well as chemical analyses to examine and evaluate the emission behaviour of car interior parts under various environmental conditions. We offer you measurements and analysis procedures in accordance with many standards and OEM-specifications, such as VDA 270, VDA 276-1, VDA 277 and VDA 278.
