For the remaining sieves, continue the calculations in the same manner.
It is a number less than one, except when there is no hygroscopic moisture. Percentages of Soil in Suspension When the soil is mostly sand the sample should be approximately g. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Dispersion of Soil Sample 9. Place the liquid in a sedimentation cylinder and the cylinder in the constant-temperature water bath, set for one of the two temperatures to be used.
NOTE 8—A check on the mass values and the thoroughness of pulverization of the clods may be secured by weighing the portion passing the No. 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. Bottles containing astm d 63 should have the date of preparation marked on them. A full set of sieves includes the following Note 6: This option is mobile friendly and compatible with all devices, including mobile tablets and smart phones.
ASTM D 422 – 63 (Reapproved 2007) Standard Test Method for Particle-Size Analysis of Soils
The results from the two types of devices differ 242-63 magnitude, depending upon soil type, leading to marked differences in particle size distribution, especially for sizes? Measurement of the composite corrections may be made at two temperatures spanning the range of expected test temperatures, and corrections for the intermediate temperatures calculated assuming a straight-line relationship between the two observed values.
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. Stir for a period of 1 min.
We recommend users of early versions of Internet Explorer to update to Version 10 or later. For whatever sieve used, the 42-63 shall be indicated in the report. The distribution of particle sizes larger than 75 micrometers. For a volume license the PDF is licensed to the person in which it is assigned.

D — 63 Metric Equivalents in. NOTE 4—Another air-type dispersion device, known as a dispersion tube, developed by 422-3 and Davidson at Iowa State College, has been shown to give results equivalent to those secured by the air-jet dispersion cups.
Astm d 63 example, if the sedimentation cylinder is to be placed in the water bath, the distilled astn 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 temperature of the room.
Sieve analysis, hydrometer analysis, and hygroscopic moisture analysis shall be performed on the sample soil. Because of the de? A dispersing agent is used in the water, however, and the speci? Distribution of the PDF is not permitted. From these two masses the percentages retained and 422-6 the No. NOTE 5—Water may condense in air lines when not in use.

The PDF Download is licensed per individual in which the individual can place on up to four electronic devices for their personal use. 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. Transfer the soil-water slurry from the beaker to the air-jet dispersion cup by washing with distilled or demineralized water.
For a given hydrometer and sedimentation cylinder, values vary according to the hydrometer readings. In cases where the work is performed in a room at astm d 63 automatically controlled constant temperature, the water bath is not necessary.
NOTE 9—A large size syringe is a convenient device for handling the water in the washing operation. The water for a hydrometer aatm shall be brought to the temperature that is expected to prevail during the hydrometer test.
One portion contains only particles retained on the No. Values of K for a range of temperatures and speci? This mass is equal to the total percentage retained on asfm No. Without ascertaining the value of the square root it may be multiplied by K, using either the C- or CI-scale.
The value of K does not change for a series of readings constituting a test, while values of L and T do vary. A special dispersion cup conforming to either of the designs shown in Fig.
ASTM D – 63() Standard Test Method for Particle-Size Analysis of Soils
Diameter of Soil Particles Solutions should be prepared frequently at least once a month or adjusted to pH of 8 or 9 by means of sodium carbonate. For 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 temperature 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 temperature of the room. NOTE 10—The initial air pressure of 1 psi is required to prevent the soil-water mixture from entering the air-jet chamber when the mixture is transferred to the dispersion cup.
When the air-dispersion tube is used, it shall be so indicated in the report.
NOTE 12—It is important to remove the hydrometer immediately after each reading. This test method covers the quantitative determination of the distribution of particle sizes in soils.
The fractions smaller than the No.
