ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
Sodium s1141-98 NaHCO 3. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine r1141-98 applicability of regulatory limitations prior to use. 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.
For preparation of substitute ocean water, aliquots of the? NOTE 2—The lack of organic matter, suspended matter, and marine life in this solution does not permit unquali?
From a scientific perspectiveartificial seawater has the advantage of reproducibility over natural seawater since it is a standardized formula. Trace elements, occurring naturally in concentrations below 0. Examples are for tests on oil contamination, detergency evaluation, and corrosion testing.
A number in parentheses indicates the year of last reapproval. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as d1141-98 of the standard. While all of the compounds listed in the recipe above are inorganicmineral salts, some artificial seawater recipes, such as Goldman and McCarthy make use of trace solutions of vitamins or organic compounds.
Only a few millilitres of NaOH solution should be required.
ASTM D1141 – 98(2013)
Store in well stoppered amber glass containers. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Historical Version s – view previous versions of standard. 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 of velocity, salt atmospheres, or organic constituents are involved.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Synthetic seawater is also known as artificial seawater and substitute ocean water.
Strontium chloride SrCl 2.
Note 2 — The lack of organic matter, suspended matter, and marine life in s1141-98 solution does not permit unqualified acceptance of test results as representing performance in actual ocean water. The substitute ocean water with heavy metals, prepared in accordance with Section 7, will have the complete composition shown in Table X1.
Typically, laboratory grade water is used when making synthetic salts . Current edition approved Aug.
Artificial seawater is primarily used in marine biology and in marine and reef aquariaand allows the easy preparation of media appropriate for marine organisms including algaebacteriaplants and animals. Calcium chloride CaCl 2. The tables below present qstm example of an artificial seawater 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.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Link to Active This link will always route to the current Active version of the standard. There are various applications for ASTM D synthetic seawater d114-198 corrosion studies, ocean instrument calibration and chemical processing.
