Scope
Content
This SAE Aerospace Standard (AS) defines the materials, apparatus and procedure for sizing and counting of particulate contamination, 5 µm or greater, in hydraulic fluid samples by membrane filtration with microscopic counting.
The microscopic counting method is capable of counting particulate matter in samples withdrawn from fluid power systems as identified by the 12 classes of AS4059 and projected beyond these for the five standard ranges specified and can thus serve as the primary document to determine acceptability.
It is also capable of revealing but not measuring evidence of abnormal amount of water, other fluids, fine particulate and other materials, especially fibers and metals.
It is applicable to all military, civil, space vehicles and test equipment.
Rationale
Content
There is a need to upgrade this document from a recommended practice to an aerospace standard to reflext its usage in the aerospace industry. This document has been changed to reflect this upgrade.
