ASTM D933 - 84(2012) Standard Practice for Reporting Results of Examination and Analysis of Water-Formed Deposits


Source: ASTM International

The results are used to characterize the scale formed and used to evaluate the quality of water used in the unit. Characterizing the scale will assist in the design of the water treatment process to avoid further scale buildup. The use of modern up-to-date chemical detection units will increase the usefulness of the practice.

1. Scope

1.1 This practice covers the manner in which the results of examination and analysis for inorganic constituents of deposits formed from waters are to be reported.

1.2 While various practices of reporting the analysis of water-formed deposits are in use, this practice is intended as a rational and comprehensive practice for general application. For use in specific industries or individual cases, molecular combinations may be useful and desirable.

1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
