ASTM D Water Absorption (24 hr). %. ASTM D Mechanical. Nominal Value Unit. Test Method. Tensile Modulus (73°F). E+6 psi. ASTM D Rate of Water and Moisture Absorption. The rate of water absorption is. ASTM‐ D， after 24 hours in water. 0. 23~0. 26％. The rate of water and moisture. Water Absorption 24 Hour/Equilibrium ASTM D Scope: Water absorption is used to determine the amount of water absorbed under specified conditions.
Test Method for Water Absorption of Plastics Can Anyone tell me the available properties yield and ultimate strengths of both specs?
Thank you, Jeff. Please upgrade your browser or contact your System Administrator for A wide variety of astm a options are available to you, such as aisi, api, and astm. You can also choose from hot rolled, erw, and cold drawn.
As well as from structure pipe, fluid pipe, and gas pipe.
And whether astm a is valve steels, or mold steel. Today, some 12, ASTM standards are used around the world to improve Material Notes Maximum thickness of 5.

Test Specimen 5. Permissible variations in thickness are NOTE 3—If a static charge interferes with the weighing, lightly rub the surface of the specimens with a grounded conductor. Tolerance for the mm dimension is 62 mm and This test method and ISO 62 are technically equivalent when the test specimen described in 5. When comparison of absorption values with molded plastics is desired, specimens 3.
Permissible variations in thickness shall be 0. Procedure 7. The diameter of the specimen shall be the diameter of the finished rod.
For tubes 76 mm 3 in. The cut edges shall be made smooth by finishing with No. Sawing, machining, and sandpapering operations shall be slow enough so that the material is not heated appreciably.
NOTE 4—In using this test method the amount of water absorbed in 24 h may be less than it would have been had the immersion not been interrupted. NOTE 2—If there is any oil on the surface of the specimen when received or as a result of machining operations, wash the specimen with a cloth wet with gasoline to remove oil, wipe with a dry cloth, and allow to stand in air for 2 h to permit evaporation of the gasoline.
If gasoline attacks the plastic, use some suitable solvent or detergent that will evaporate within the 2-h period.
The weighings shall be repeated at the end of the first week and every two weeks thereafter until the increase in weight per two-week period, as shown by three consecutive weighings, averages less 5. Dimensions not listed shall be measured within 0.
The difference between the substantially saturated weight and the dry weight shall be considered as the water absorbed when substantially saturated. At the end of 6 4 min, the specimens shall be removed from the water and cooled in distilled water maintained at room temperature.
An American National Standard
After 15 6 1 min, the specimens shall be removed from the water, one at a time, all surface water removed with a dry cloth, and the specimens weighed to the nearest 0.
The initial slope of this graph is proportional to the diffusion constant of water in the plastic.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. Test Procedure: This test method and ISO 62 are technically equivalent when the test specimen described in 5.
Water Absorption ASTM D570
This test method and ISO 62 are technically equivalent when the test specimen described in 5. 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.
