Storage tests and electrochemical
tests have several parameters in
common:
• The statistical confidence
increases with the number of
replicate samples for each
measurement
• Both tests must be conducted
for the appropriate length of
time
• Appropriate data collection,
analysis and interpretation
procedures
• Temperature does not
accelerate the corrosion; and
• Inappropriate parameters and
procedures invalidate test results
In the next issue, I’ll complete the
discussion with some details on
electrochemical corrosion testing
and an example of how much an
unexpected corrosion incidence
could cost.

for reading and I’ll see you in March. Spray
