1 Scope

This standard specifies the method of dynamic or static extracting oil from the lubricating oil system and hydraulic system fluid sample.

When the need for lubricating oil and hydraulic oil systems fluid analysis, the need for proper sampling operation.

In order to obtain reliable and comparable results of the analysis, sampling should be carried out under specified conditions and operating environment.

When the system reaches operating temperature, from the turbulent state of the fluid samples, a process known as dynamic sampling. If not dynamic sampling can Samples were taken from the tank to the system, this method is called static sampling.

Note. Static sampling process, a size larger than 20µm rapidly precipitated particles.

This standard specifies the dynamic and static methods of sampling and sample bottling.

Extracting a sample through the filter with the "standard slide" in comparison, provide reference for device manufacturers to develop manual.
