Lube oil testing
Lubricant testing is recommended for the
To study the condition (wear, and so
on) of the machine being lubricated. If
there is a problem with the lubricant,
there is a strong possibility that the
machine will need maintenance.
To determine if the lubricant is meeting
LUBRICANT OIL ANALYSIS
ASTM D 4378-97 is Standard Practice
for In-Service Monitoring of Mineral
Turbine Oils for Steam and Gas
LUB OIL DIAGNOSIS
Degradation of lubricant oil.
Impurities in lubricant oil.
Wear debris in lubricant oil.
Wear Debris Analysis
The continuous trending of wear rate
monitors the performance of machine
/machine components and provide
early warning and diagnosis.
Oil condition monitoring can sense
danger earlier than vibration
Minimize component wear.
Extend equipment life.
Ensure lubricant suitability for continued
Monitor viscosity levels for optimum
Reduce unscheduled downtime.
Boost company profit.
Wear particle analysis
Trending ( quantitative) :
wear particles concentrations to
identify onset of abnormal wear.
Particle identification (qualitative ):
microscopic analysis to predict source
,cause and scope of wear .

Surface fatigue (rolling)
This type of wear
typically occurs with

These particles are
often too small.
Due to acidic

Oxide particles, which are either red
or black iron oxides, are produced
from chemical reactions between iron
Red oxides are an indication of
moisture in the system, while black
oxides indicate inadequate lubrication
and excessive heat generation in the
Shape of Wear particles
Cutting Cutting wear particles are abnormal.
They are generated as a result of one surface
Fatigue This class contains particles that are
formed as an effect of repeated passes through
the system which results in plastic deformation
of particles. They have a smooth surface and
irregularly shaped circumference.
Shape of Wear particles
Sliding Sliding particles have long
shape and irregular edge. They are
smaller than fatigue particles.
Sphere Spherical particles can be
generated if there is insufficient
lubrication or there is a depletion of
EP additives in high load.
ANALYSIS & DIAGNOSIS
This monitors equipment condition
and can identify types and possible
sources of wear and contamination.
It includes a Particle Count or
A Particle Count identify all particles
present measuring 4 to 100 microns
