Sketches
•
Show layout of structure(s).
•
Show location of measurements with polarity of measurement.
•
Record name and serial numbers of all instruments used.
Site Conditions
Always indicate unusual site conditions.
Legibility
Data must be legible if it is to be of any value.
Computer Records and Spreadsheets
Nearly all corrosion records today are kept on computer databases. Usually
these databases show the test points, date of last test, the measurement
itself, whether or not the data meet the selected criterion, and when the next
test is due. Printouts are then generated at the appropriate times for
technicians to take into the field for the next scheduled tests. The latest data
are then entered into the database. Spreadsheets can also be generated
showing test points that do not meet criteria. These can be taken into the
field for trouble shooting.
If you have been collecting data on a computer data logger, the data can be
entered directly into a computer. Graphs and spreadsheets of data can be
generated, or the data can be downloaded into the company computer
system.
Large companies, particularly those with operations spread over a large
area, are now using Internet access for corrosion control data. This makes it
possible for all data in a technician’s area to be available without having to
have a large computer system in local offices.
Facility Maps and Work Documentation
Companies that operate underground plants, such as pipelines or cables,
maintain atlas maps showing the location of structures, test points, cathodic
protection installations, and many other data. The same is true of many
large industrial plants, refineries, college campuses, and similar facilities.
