INTERWOOLLABS Report on Round Trials Completed in 2005, INTERWOOLLABS Management Committee

Abstract

This report summarises the INTERWOOLLABS International Harmonisation (IH) Round Tests completed in 2005. 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.
