BOSAL thoroughly tests its entire product range in house, to make sure only safe and reliable quality products reach its customers.

Starting off with virtual testing, to optimize and validate the design, allows BOSAL to perform physical tests on already enhanced prototypes. As a result, BOSAL cost-efficiently improves endurance performance of all products its clients receive.

Virtual simulation and testing

Design validation starts with virtual simulations, which verify endurance based on virtual input of engine vibration, road vibrations and gas flow temperatures. Virtual simulation enables a fast optimization of the design, after which BOSAL builds prototypes and submits them to a series of physical tests.

BOSAL's capabilites

BOSAL has built extensive competences and specific know-how in different fields of endurance validation:

Thermal loading

This test entails rapidly heating up the test sample up to 1000°C, followed by an extremely fast cool down by means of a water quench or a cold air flow.

  • Internal thermal cycling
  • External thermal cycling with water quench
  • Thermo-mechanical fatigue

Vibration loading

Submitting components to recorded or synthesized vibration signals tests the vibration resistance of a product. Vibration levels can go up to 100G for some products, which is sometimes combined with hot gas flow through the component.

  • Road load data acquisition
  • Engine vibration
  • Road vibration
  • Flexible decoupling design
  • Hanger system design
  • Fatigue testing
  • Accelerated vibration testing
  • Hot vibration tests of catalyst canning

Internal & external corrosion

  • Chemical resistance  
  • Material grade selection
  • condensate evacuation


All performance tests meet BOSAL’s standards. Each and every product that passes design validation, complies with the market’s legal requirements and OE customer specifications.
