Development of a design reference for assessing the ageing of plastic moulded products for medical technology (KoReAlt)

Subject of research

  • Development and validation of characterisation methods for mapping the ageing behaviour of plastics in medical devices
  • Further development of artificial ageing models (beyond the ASTM F1980 standard) to shorten development times
  • Selection of relevant materials and sterilisation parameters based on market analyses and reference products
  • Establishment of a scientifically sound, time-optimised ageing protocol for single-use and reusable medical devices

Project goals

  • Development of a representative test specimen for predicting the ageing behaviour of plastics
  • Validated ageing model with 20% time savings compared to ASTM standard
  • Database for material behaviour of selected medical grade plastics under sterilisation and ageing
  • New methodological standards for SMEs and suppliers in the medical technology industry
  • Basis for future ‘gold standards’ in material testing and approval
