Scope

This document 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 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 if a suitable sampling device is not fitted.

This document can be used for offline and online sampling. The samples taken are used for particulate contamination analysis.
