REPORTING CLEANLINESS LEVELS OF HYDRAULIC FLUIDS

1986-03-01
HISTORICAL
J1165_198603
This SAE Recommended Practice has been formulated to advance and endorse the use of the ISO (International Organization for Standardization) Solid Contaminant Code as the universal means for expressing the level of particulate contaminant in hydraulic fluid and for specifying acceptable limits of cleanliness. Worldwide approval was gained for this coding system because it provides a simple, unmistakable, meaningful, and consistent means of communication between suppliers and users. The code applies to all types of hydraulic (liquid) fluids used in fluid power and control systems as applied to self-propelled machines as referenced in J1116.

CURRENT
J748_201912
This SAE Recommended Practice has been set up by Subcommittee 4 of the Off-Road Machinery Technical Committee and is primarily for directional control valves on construction and industrial machinery equipment as referenced in SAE J1116. The purpose is to establish port area to flow relationship and match valve spool eye ends in relation to rated capacity. Port connections are optional for either the 4-bolt split flange connection or the internal straight thread "O" ring connection.
