ASTM D 422 – 63 (Reapproved 2007) Standard Test Method for Particle-Size Analysis of Soils
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 temperature of the room. From these two masses the percentages retained and passing the No. Stir for a period of 1 min. When the air-dispersion tube is used, it shall be so indicated in the report.

The mass of air-dried soil selected for purpose of tests, as prescribed in Practice Dshall be sufficient to yield quantities for mechanical analysis as follows: D — 63 Reapproved. A full set of sieves includes the following Note 6: Such a device is illustrated in Fig. NOTE 11—The number of turns during this minute should be approximately 60, counting the turn upside down and back as two turns.
Dispersion of Soil Sample 9.
D mm11? The distribution of particle sizes larger than 75 micrometers. Use on a local area network or other network is not permitted. Bring the liquid and the hydrometer to the other temperature to be used, and secure the composite correction as before.
Readings shall be taken at the top of the meniscus formed by the suspension around the stem, since it is not possible to secure readings at the bottom of the meniscus. NOTE 9—A large size syringe is a convenient device for handling the water in the washing operation. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Stir until the soil is thoroughly wetted.
The PDF Download is licensed per individual in which the individual can place on up to four electronic devices for their personal use. Transfer the material on the No.

This test method covers the quantitative determination of the distribution of particle sizes in soils. Originally approved in Last previous astm d 63 approved in as D — 63? Solutions should be prepared frequently at least once a month or adjusted to pH of 8 or 9 by means of sodium carbonate. NOTE 7—Solutions of this salt, if acidic, slowly revert or hydrolyze back to the orthophosphate form with a resultant decrease in dispersive action.
Small variations of temperature do not introduce differences that are of practical signi?
This set consists of the following sieves: No further reproductions authorized. Determination of Composite Correction for Hydrometer Reading 7.
ASTM D – 63()e2 Standard Test Method for Particle-Size Analysis of Soils (Withdrawn )
A superscript epsilon e indicates an editorial change since the last revision or reapproval. D — 63 Metric Equivalents in.
Add distilled or demineralized water, if necessary, so that the total volume in the cup is mL, but astj more. NOTE 7—Solutions of this salt, if acidic, slowly revert or hydrolyze back to the orthophosphate form with a resultant decrease in dispersive action. As soon as the reading is taken, carefully remove the hydrometer and place it with a spinning motion in a graduate of clean distilled or demineralized water. When the hydrometer analysis is not made on a portion of the soil, the preparation of the graph is optional, since values may be secured directly from tabulated data.
Current edition approved Nov. 242-63 16—This zstm of graph represents the gradation of the sample tested. Dimensions of both hydrometers are the same, the scale being the only item of difference.
A dispersing agent is used in the water, however, and the speci? When the air-dispersion tube is used, it shall be so indicated in the report. 4422-63
This set consists of the following sieves: The results from the two types of devices differ in magnitude, depending upon soil type, leading to marked differences in particle size distribution, especially for sizes?
