Failure can often result from the combined effect of many factors. So, our failure investigations often involve a multidisclipinary approach to find the cause, including: 

  • Microscopic examination
  • Chemical analysis of material (including additives)
  • Material degradation analysis (polymer molecular distribution)
  • Thermal analysis
  • Manufacturing process audit (including potential computer simulation)
  • Mechanical testing (including 'real life' simulation to replicate service conditions)

Test programmes are individually designed, and tailored to each project.
