Functional Materials Standardisation Activities

The Composites and Polymeric Materials Group use a broad range of measurement technology to understand material behaviour, supporting businesses of all sizes.

NPL Composites and Polymeric Materials researchers play a significant role in the ISO standardisation process for composites and plastics within ISO TC61, chairing working groups and leading projects. Input to the following standards has been made over recent years.

If you would like to propose standardisation of a test method that fits within these categories please contact Michael Gower for composites, and Martin Rides for polymeric materials.

  • Composites
  • Polymer melt rheology
  • Thermal properties of polymers
  • Ageing, chemical and environmental resistance of polymers
  • Additional polymer standards activity
