Corrosion engineers in the oil- and gas-producing industry are often charged with the responsibility of evaluating and controlling the quality of injection waters. Unfortunately much of the data available are inadequate, misleading, or difficult to interpret. This standard was prepared to provide standard test methods for use by these engineers in evaluating water quality for injection waters.

This standard was originally prepared in 1973 by NACE Task Group T-1C-12, revised in 1976, reaffirmed in 1983, and revised in 1984 and 1992 by T-1C-20, components of Unit Committee T-1C on Detection of Corrosion in Oilfield Equipment. T-1C was combined with T-10 on Corrosion Monitoring and Control of Corrosion Environments in Petroleum Production Operations. This standard was revised by T-1 D-47 in 1999 and is issued by NACE International under the auspices of Group Committee T-1 on Corrosion Control in Petroleum Production.

 This standard describes two test methods for evaluating water quality for subsurface injection: Procedure A-rate versus cumulative volume test (for water-quality monitoring) and Procedure 8-suspended solids test (for diagnosis or monitoring). These two test methods are intended to provide standardized water quality in the petroleum production industry. The test methods describe the apparatus required, test conditions, test procedures, reporting procedures, and supplementary tests. Interpretation of the results is beyond the scope of this standard. The bibliography supplies sources of interpretation methods.
