Examples are for tests on oil contamination, detergency evaluation, and corrosion testing. Also the rapid depletion of reacting elements present in low concentrations suggests caution in direct application of results. The pH after adjustment with 0. The tables below present an example of an artificial seawater Examples are for tests on oil contamination, detergency evaluation, and corrosion testing.
The substitute ocean water with heavy metals, prepared d1141-988 accordance with Section 7, will have the complete composition shown in Table X1. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in d1141-988 standard.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Calcium chloride CaCl 2. From a scientific perspectiveartificial seawater has the advantage of reproducibility over natural seawater since it is a standardized formula. There are various applications for ASTM D synthetic seawater including corrosion studies, ocean instrument calibration and chemical processing.
Qstm elements, occurring naturally in concentrations below 0. Only a few millilitres of NaOH solution should be required. Note 2 — The lack of organic satm, suspended matter, and marine life in this solution does not permit unqualified acceptance of test results as representing performance in actual ocean water.

Where corrosion is involved, the results obtained from laboratory tests may not approximate those secured under natural testing conditions that differ greatly from those of the laboratory, and especially where effects d111-98 velocity, salt atmospheres, or organic constituents are involved. Artificial seawater abbreviated ASW is a mixture of dissolved mineral salts and sometimes vitamins that simulates seawater.
