INTERWOOLLABS Report on Round Trials Completed in 2004

Abstract

This report summarises the INTERWOOLLABS International Harmonisation (IH) Round Tests completed in 2004. The programs covered by this report include:

• Mean Fibre Length (as Hauteur) measured by the Almeter Method
  (IWTO-17)
• Mean Fibre Diameter measured by the Projection Microscope Method
  (IWTO-8)
• Mean Fibre Diameter measured by the Airflow Method (IWTO-6)
• Mean Fibre Diameter measured by the OFDA Method (IWTO-47)
• Mean Fibre Diameter measured by the Laserscan Method (IWTO-12)

The results are presented in graphical form and show the ranges in measured results that can be expected for each of the above methods. In general, the between-laboratories differences increase as the value of the measured characteristic increases.
