1. INFRA RED THERMOFRAPHY REPORT
by
ISMAIL BIN YUSOF
SUMMARY OF THE REPORT
The pages of the report are formatted to document “exceptions” (abnormally warm and
cool components) observed during the survey. Each page documents are exception.
The Thermograph is the “Heat Picture” that shows the problem. Accompanying this is
a photograph of the same then with an arrow or circle to identify the “HOT SPOT’.
The text of the pages identifies the date, area, place of equipment and the problem.
The “priority” of each problem is given based on the temperature rise of the hot spot
areas above reference, which is usually a similar component under the same conditions.
This can be useful in determining the immediacy of the needed repair. The table below is
used as a GUIDE for priority. Considerations such as safety, criticality of the equipment
and availability of spares must also be taken into consideration by maintenance personnel
when determining priority.
Priority Delta Temperature of C Comments
Alert 0 to 20 A problem exists, schedule
action as convenient
Alarm 21 to 40 Schedule action soon
Danger Above 40 Schedule action
immediately
At the bottom of this page is a recommendation action area to suggest the correction
action should be taken. However the actual repair procedure will be the decision of the
owners and maintenance personnel of the equipment. This should be based on what is
found once the problem investigated. REMEMBER the thermography is a tool to detect
the problem area in advance so that the maintenance personnel can project schedule
maintenance before it breakdown. This what people say Predictive Maintenance or
Condition Based Maintenance program.
The last of the report is an equipment list, which the equipment was inspected, whatever
any problems were found and on which page a problem is documented if applicable. This

2. is useful in knowing what was checked. It also senses as a checklist for the next survey,
thus maximizing the use of time on future inspection..
Along the right of the thermography is a scale showing the temperature range and the
corresponding color. The hottest will be white and the cool will be blue. The area of
concern is usually outlined with a rectangle, round or ellipse. A label containing the
maximum temperature within the outline identifies the temperature of interest. Cursor
points or another outline is used to indicate temperatures at the reference points.
Sometime the isotherming function will be used to identify the warmest area of
interest. This will be the color are filling in a space on the thermograph, which
temperature of the color area appearing on the scale at the right of the image.
