1.1This practice covers the preparation of solutions containing inorganic salts in proportions and concentrations representative of ocean water.2

Note 1-Since the concentrations of ocean water varies with sampling location, the gross concentration employed herein is an average of many reliable individual analyses. Trace elements, occurring naturally in concentrations below 0.005 mg/L, are not included.

1.2This practice provides three stock solutions, each relatively concentrated but stable in storage. For preparation of substitute ocean water, aliquots of the first two stock solutions with added salt are combined in larger volume. An added refinement in adjustment of heavy metal concentration is provided by the addition of a small aliquot of the third stock solution to the previous solution.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This 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.
