Hydraulic fluid power. Determination of the particulate contamination level of a liquid sample by automatic particle counting using the light-extinction principle1 Scope This International Standard specifies an automatic particle counting procedure for determining the number and sizes of particles present in hydraulic fluid bottle samples of clear, homogeneous, single phase liquids using an automatic particle counter (APC) that works on the light extinction principle. This International Standard is applicable to the monitoring of a) the cleanliness level of fluids circulating in hydraulic systems, b) the

and routine application of a procedure for the effective liquid extraction of particulate matter from the surfaces of single-use components and assemblies designed for use in biopharmaceutical manufacturing processes

The plane of the lens shape is now defined as being the plane containing the vertical centreline parallel to the horizontal centreline of the individual lens based on the apex of the groove instead of being based on the plane tangential to the demonstration lens

as well as the consequent costs and absenteeism

examples of such methods are incorporated into other standards (such as ITU Rec
