This International Standard specifies methods for determining the level of participate contamination in liquids used in hydraulic systems by counting the number of particles deposited on the surface of a membrane filter using an optical microscope. It includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems. Particle sizes ≥ 2 μn can be sized and counted by this method, but the resolution and accuracy of the results wiB depend upon the optical system used and the capabilities of the operator. All hydraulic fluids with a wide range of contamination levels can be analysed according to this International Standard. However, the counting uncertainty at the larger particle sizes increases if the volume filtered is reduced to allow smaller sized particles to be counted, where a fine precipitate or a high particle concentration is present.

This powerpoint presentation begins by providing a brief overview of biological filtration (biofiltration), including basic aspects of biological processes and a physical concept of a biofilm system. The presentation covers modeling and a unifying concept, pharmaceuticals removal, and membrane pretreatment. The presentation summary includes: classical and newer objectives for biofiltration include no design criteria and the need for a practically based modelling approach; dimensionless contact time (X) useful unifying parameter; simplification and extension of X possible; biofilters can remove certain pharmaceuticals and endocrine disrupting compounds; biofiltration as a pretreatment can reduce membrane fouling, although further development and experimental verification necessary; and, the Biofiltration Factor (BF) -- a (new) possible practically-oriented design parameter. Includes figures.

This European Standard specifies a procedure for the comparative evaluation of resistance to soiling of an organic coating on a metallic substrate (coil coating) in an outdoor exposure environment, particularly the soiling defect known as "Tiger stripes".
