The result is reported in units of by volume in the vapor phase.

ASTM D5705 is a standard test method that describes a procedure for determining the water absorption of plastics under specified conditions. For anyone working with polymer materials — product designers, materials engineers, quality managers, and manufacturers — understanding and using a reliable water‑absorption test like D5705 is important because moisture uptake can affect mechanical properties, dimensional stability, electrical behavior, and long‑term durability.

: A representative sample of the fuel oil is collected in a specialized one-liter glass container, filling it to 50% of its capacity. Equilibration : The container is heated in a water bath to and agitated to ensure the H2Scap H sub 2 cap S reaches equilibrium between the liquid and vapor phases.

When searching for "ASTM D5705 PDF," users often confuse it with other similar standards. Here is a comparison:

Maritime organizations, such as the International Maritime Organization (IMO) under the MARPOL convention, enforce strict limits on the allowable H2Scap H sub 2 cap S The result is reported in units of by

The operator inserts a length-of-stain detector tube into the headspace through a specialized sampling septum or cap configuration. Using the sampling pump, a fixed volume of headspace gas is drawn through the tube.

The current version of the standard, , includes specific constraints for its use:

Collect the residual fuel oil sample directly from the source (pipeline, storage tank, or bunker manifold) into the test container. The container must be filled to exactly : A representative sample of the fuel oil

The sample is heated to a specific temperature, usually 60° C or higher, to encourage H₂S to leave the liquid and enter the vapor phase (headspace).

within the liquid phase. However, during storage, transport, or agitation, this dissolved gas readily migrates out of the liquid and accumulates in the "headspace" or ullage of a storage tank. A relatively low concentration in the liquid phase can evolve into thousands of ppm within an enclosed vapor space. Regulatory Compliance
