In 2006 a Round Robin study was conducted on a number of laboratory test methods listed in
NACE TM0104-2004, TM0204-2004, TM0304-2004 and TM0404-2004 in order to establish the
reproducibility of the test methods. The results from this study indicated that significant differences in
results could be achieved between different laboratories testing the same coating systems.
This paper discusses the results from this study, including statistical analysis of the data
generated, gives guidance on how laboratory test results should be interpreted and provides some
suggestions for future test method development.
