Description / Abstract:
To describe laboratory methods for determining and reporting the
contaminant level of the wetted portion of hydraulic fluid power
components, parts, subsystems and systems, and of fill fluids. For
each type of item it provides a method of obtaining the liquid
sample and the contamination level thereof. It also includes
procedures for establishing a sampling plan and guidelines for
establishing levels of acceptance, but does not set those
levels.
Purpose
To provide a basis for measuring and reporting cleanliness
levels so that built-in contamination and premature failures of
hydraulic systems can be minimized.
