This part of ISO 2884 is one of a series dealing with the sampling and testing of paints, varnishes and relatedproducts.It supplements ISO 2431:1993, Paints and varnishes — Determination of flow time by use of flow cups.It specifies the general procedure to be followed in determining the dynamic viscosity of paints, varnishes andrelated products at a rate of shear between 9 000 s?1 and 12 000 s?1.The value obtained gives information about the resistance offered by the material to brushing, spraying and rollercoating during application.The method specified in this part of ISO 2884 is suitable for all paints and varnishes whether they are Newtonian inbehaviour or not. Materials containing dispersions of large particles will produce spurious results.
