Organization: ISO
Publication Date: 1 January 1992
Status: active
Page Count: 10
ICS Code (Filters, seals and contamination of fluids): 23.100.60
scope:

This International Standard specifies procedures for extracting fluid samples from a hydraulic fluid power system under operation.

The preferred method is to extract fluid samples from a main flowline of an operating hydraulic system in such a manner that the particulate contaminant in the sample is representative of the fluid flowing at the point of sampling.

An alternative method is to extract a sample from the reservoir of an operating hydraulic system, but this method should only be used if a suitable sampler is not fitted.

The samples taken are used for particulate contamination analysis.
