New Test Method for Total Hardness of Water, Waste Water with Color Using Titration and Optical Spectroscopy as End Point Determination

1. Scope

The study of water, the promotion of knowledge thereof, and the standardization of terminology methods for:
* Sampling and analysis of water, waterborne materials, and wastes, water- formed deposits and fluvial sediments,
* Surface-water hydraulics and hydrologic measurements,
* The determination of the performance of materials or products used to modify water characteristics, and
* The determination of the corrosivity or deposit forming properties of water.
The term "water" includes, but is not limited to, surface waters (rivers, lakes, artificial impoundments, runoff, etc.), groundwaters and springwaters, wastewaters (mine drainage, landfill leachate, brines, waters resulting from atmospheric precipitation and condensation (with the exception of acid deposition), process waters, potable waters, glacial melt waters, steam, water for subsurface injection and water discharges including waterborne materials and water-formed deposits.
The work of the Committee will be coordinated with other ASTM Committees and other societies and organizations having mutual interests.
