Scope

Calcium and magnesium salts in water are the primary components of water hardness which can cause pipe or tube scaling.

1.1 These test methods cover the determination of calcium and magnesium in water by complexometric titration and atomic absorption spectrometric procedures. Two test methods are included, as follows:

	Sections
Test Method A-Complexometric Titration	7 to 14
Test Method B-Atomic Absorption Spectrometric	15 to 23

1.2 This standard does not purport to address all of 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. Specific hazard statements are given in 12.2.6 and 20.6.
