NACE International standard recommended practice defines data categories and specific data elements (fields) that are considered necessary for meaningful transfer of electrochemical polarization curve data from one laboratory to another. It is thus intended to facilitate the use of data by different laboratories and does not imply or endorse any particular database design or schema.

This standard was prepared by Task Group T-3U-4, a component of Unit Committee T-3U on

Computers in Corrosion Control, and is issued under the auspices of Group Committee T-3 on

Corrosion Science and Technology. The scope of the task group was "to enhance the ability to share polarization data through electronic data exchange by developing a standard format." Task group participants included representatives from materials groups from chemical and process industries, research institutions, technical associations, and government laboratories.

1.1 This standard identifies the requirements for the complete specification of parameters necessary for the meaningful interchange of electrochemical polarization curve data files among different computer systems and laboratories.

1.2 Reliable comparisons of corrosion data from multiple sources are expedited when data are provided for as many of the listed fields as possible. When data are limited, some degree of uncertainty is present.

1.3 This standard provides a useful reference to be consulted before initiating a corrosion test to ensure plans are made to record relevant data.

1.4 Reference should also be made to NACE Standard RP0690 (latest revision), "Standard Format for Collection and Compilation of Data for Computerized Material Corrosion Resistance Database lnput.
