BS EN ISO 2884-2:2006

1   Scope This part of ISO 2884 specifies a general procedure for determining the viscosity of paints, varnishes and related products with a viscosity of up to 34 Pas. It is applicable mainly during production and thinning. It supplements

  [ISO 2431](/search?q=ISO%C2%A02431)
  ,  Paints and varnishes — Determination of flow time by use of flow cups ; 

  
  [ISO 2884‑1](/search?q=ISO%C2%A02884%E2%80%911)
  ,  Paints and varnishes — Determination of viscosity using rotary viscometers — Part 1:
     Cone- and-plate viscometer operated at a high rate of shear . 
For more accurate methods of measurement of viscosity, refer to [ISO 3219](/search?q=ISO%C2%A03219),  Plastics — Polymers/resins in the liquid state or as emulsions or dispersions — Determination
     of viscosity using a rotational viscometer with defined shear rate. 

The apparatus specified may be used in both a laboratory and a factory environment
  to determine the viscosity of a product and to monitor the viscosity whilst thinning
  during a manufacturing process.
