Description

ASTM D1141-98-Reapproved2021

Active Standard: Standard Practice for Preparation of Substitute Ocean Water

ASTM D1141

Scope

1.1 This 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.

1.2 This 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.

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

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
