Store in well stoppered amber glass containers. Where corrosion is involved, the results obtained from laboratory tests may not approximate those secured under natural d11419-8 conditions that differ greatly from those of the laboratory, and especially ast, effects of velocity, salt atmospheres, or organic constituents are involved.
Note 2 — The lack of organic matter, suspended matter, and marine life in this solution does not permit unqualified acceptance of test results as representing performance in actual ocean water. Synthetic seawater is also known as artificial seawater and substitute ocean water.
Trace elements, occurring naturally in concentrations below 0. 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.
Also the rapid depletion of reacting elements present in low concentrations suggests caution in direct application of results. Examples are for tests on oil contamination, detergency evaluation, and corrosion testing.
