New Laboratory Area for Component Analyses in the Clean Room

In Accordance with Guidelines for Technical Cleanliness VDA 19.1 and ISO 16232

Technical cleanliness is defined by the amount of dirt on the surface of a component. To determine this, the residual dirt weight and the number, size and composition of the dirt particles are analyzed.

Test facility for technical cleanliness: Gläser RiuS Double

For thorough particle testing of Rosenberger products this system features two analysis chambers.  Depending on the geometry of the component, the appropriate space is made available.

 

Maximum component size: 50 x 30 x 30 cm

Minimum component size: 1 x 1 x 1 mm

Functions

  • Wall cleaning: for cleaning the large rinsing cabinet
  • Basin with ultrasound: especially suitable for testing small bulk materials that are difficult to handle
  • Air purity with clean room filter: for generating overpressure in the rinsing cabinet
  • Spraying: for standard inspection of most components
  • Flushing: for testing open internal areas, such as pipes and tubes, or components that will later be flowed through, such as valves, injectors or pumps
  • Flooding: for loosening particles by leaving the components in the filled basin for a defined period of time

Evaluation by laser spectroscopy: Leica DM6 M LIBS

The particles are first filtered out by the test equipment and then applied to a membrane in order to analyze the composition of the microstructures.

After taking two images with different exposures, the program automatically detects fibers, shiny metallic particles and non-metallic shiny particles.

Highly qualified laboratory staff then check the categorization of the fibers and particles and finally generate a comprehensive report that forms the basis for further optimization in production.
