The distribution of particle sizes larger than 75 micrometers. Use on a local area network or other network is not permitted. Other devices include the wash-water bottle and a hose with nozzle connected to a pressurized distilled water tank. When the air-dispersion tube is used, it shall be so indicated in the report.

Without ascertaining the value of the square root it may be multiplied by K, using either the C- or CI-scale. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. To secure the total mass of soil passing the 3? Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

The amount of the 422-63 increases as the variation from the standard temperature increases.

Nominal Diameter of Largest Particles, in. NOTE 7—Solutions of this salt, if acidic, slowly revert or hydrolyze back to the orthophosphate form with a resultant decrease in dispersive action.

Such a device is illustrated in Fig. This option is mobile friendly and compatible with all devices, including mobile tablets and smart phones. In cases where the work is performed in a room at astm d 63 automatically controlled constant temperature, the water bath is not necessary.


This water must be removed, either by using a water trap on the air line, or by blowing the water out of the line before using any of the air for dispersion purposes. NOTE 5—Water may condense in air lines when not in use.

NOTE 12—It is important to remove the hydrometer immediately after each reading. D — 63 Metric Equivalents in. Do we really need a prescribed pattern? Values of K for a range of temperatures and speci? This water must be removed, either by using a water trap on the air line, or by blowing the water out of the line before using any of the air astm d 63 dispersion purposes. If particles larger than those contained in the sample were removed before testing, the report shall so state giving the amount and maximum size.

When the soil is mostly sand the sample should be approximately g. When mechanical sieving is used, test the thoroughness of sieving by using the hand method of sieving as described above. Percentages of Soil in Suspension The inside diameter shall be such that the mL mark is 36 6 2 cm from the bottom on the inside. From these two masses the percentages retained and passing the No.

No further reproductions authorized. The balances, stirring apparatus, hydrometer, sedimentation cylinder, thermometer, sieves, water bath or constant-temperature room, beaker, and timing device used in the method are specified. At the end of 1 min set the cylinder in a convenient location and take hydrometer readings at the following intervals of time measured from the beginning of sedimentationor as many as may be needed, depending on the sample or the speci?

One portion contains only particles retained on the No. Bottles containing astm d 63 satm have the date of preparation marked on them. Extensive investigations indicate that air-dispersion devices produce a more positive dispersion of plastic soils below the ? For the remaining sieves, continue the calculations in the same manner. NOTE 2—Two types of dispersion devices are 4222-63 A full set of sieves includes the following Note 6: The distribution of particle sizes larger than 75 micrometers retained on the No.


At the end of weighing, the sum of the masses retained on all the sieves used should equal closely the original mass of the quantity sieved. Diameter of Soil Particles A full set of sieves includes astm d 63 following Note 6: This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? For both hydrometers, H and H: Current edition x Nov. The PDF 422-633 is licensed per individual in which the individual can place on up to four electronic devices for their personal use.

Current edition approved Oct. Astm d 63 example, if the sedimentation cylinder is to be placed in the water bath, the distilled or demineralized water to be used shall be brought to the astm d 63 of the controlled water bath; or, if the sedimentation cylinder is used in a room with controlled temperature, the water for the test shall be at the 4222-63 of the room.

The water 4222-63 a hydrometer test shall be brought to the temperature that is expected to prevail during the hydrometer test.
