Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as asfm of the standard. A paradigm for a skin graft substitute.

The main observed corrosion products were iron sulfides and the typical damage associated with hydrogen sulfide presence was Sulfide Stress Cracking SSC. No other units of measurement are included in this standard.

ASTM D1141 – 98(2013)

Historical Version s – view previous versions of standard. Trace elements, occurring naturally in concentrations below 0.

Gravimetric tests and surface analyses were carried out to establish both the corrosion rate and damage type exhibited by the metal. 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.


The surface damage evidences the presence of cracks with considerable magnitude and metal loss as consequences of the corrosion processes.

ASTM D – 98() Standard Practice for the Preparation of Substitute 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 of asfm, 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.

For preparation of substitute ocean water, aliquots of the first two stock solutions with added salt are combined in larger volume. Chasing the queens of the alien predator of honeybees: Link to Astn This link will always route to the current Active version of the standard.

In the present work, the susceptibility of API 5L X52 steel to corrosion processes was evaluated in the presence of high contents of hydrogen sulfide and carbon dioxide. Materials Sciences and ApplicationsVol.

A water drop in the invasiveness ocean.

The obtained results indicate that the hydrogen sulfide is the most active gas in the corrosion processes that asstm place, quite above carbon dioxide. Likewise, the presence of oxygen in the system modifies the displayed corrosion type, where corrosion products such as iron oxides and reduction in the number and extent of cracks are observed. Examples are for tests on oil contamination, detergency evaluation, and corrosion testing.

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.


Scientific Research An Academic Publisher. Note 2 — The lack of organic matter, suspended matter, and marine life in this solution does not permit unqualified acceptance of sstm results as representing performance in actual ocean water.

On the other hand, the addition of a film-forming corrosion inhibitor based on modified imidazolines eliminates completely the development of cracks, although under certain test conditions, it can favor localized pitting corrosion.
