Stir until the soil is thoroughly wetted. Values of K for a range of temperatures and speci? Or a Max density of Isn’t evenly distributing astm d 63 rammer blows for a proctor clear enough? Small variations of temperature do not introduce differences that are of practical signi?
This test method covers the quantitative determination of the distribution of particle sizes in soils. Open the control valve so that the gage indicates 1 psi 7 kPa pressure Note D — 63 Reapproved. NOTE 5—Water may condense in air lines when 4222-63 in use. Sieve analysis, hydrometer analysis, and hygroscopic asym analysis shall be performed on the sample soil. Current edition approved Oct. The distribution of particle sizes larger than 75?
The results from the two types of devices 422-6 in magnitude, depending upon soil type, leading to marked differences in particle size distribution, especially for sizes?
A air gage must be on the line between the cup and the control valve. 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 4222-63 with controlled temperature, the water for the test shall be at the temperature of the room.

Use numerical value of one in both instances in the equation. To secure the total mass of soil passing the 3?
Determination of Composite Correction for Hydrometer Reading 7. Use on a local area network or other network is not permitted. Plasticity Index Under 5 6 to 20 Over 422-3 Dispersion Period, min 5 10 15 Soils containing astn percentages of mica need be dispersed for only 1 min. 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.
The distribution of particle sizes larger than 75 micrometers retained on the No. A dispersing agent is used in the water, however, and the speci? 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.
NOTE 7—Solutions of this salt, if acidic, slowly revert or hydrolyze back to the orthophosphate form with a resultant decrease in dispersive action. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Does it really matter when the next shovelful of earth from the same excavation is minutely different. It is a number less than one, except when there is no hygroscopic moisture.
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.
After the dispersion period, reduce the gage pressure to 1 psi preparatory to transfer of soil-water slurry to the sedimentation cylinder.
If particles larger than asfm contained in the sample were removed before testing, the report shall so state giving the amount and maximum size. Add distilled or demineralized water, if necessary, so that the total volume in the cup is mL, but no more. For whatever sieve used, the size shall be indicated in the report. NOTE 9—A large size syringe is a convenient device for handling the water in the asstm operation.
For hydrometer H the composite correction 42-263 the difference between this reading and one; for hydrometer H it is the difference between the reading and zero. Other devices include the wash-water bottle and a hose with nozzle connected to a pressurized distilled water tank.

Astn 10—The initial air pressure of 1 psi is required to prevent the soil-water mixture from entering aztm air-jet chamber when the mixture is transferred to the dispersion cup. Dispersion of Soil Sample 9. This option is mobile friendly and compatible with all devices, including mobile tablets and smart phones.
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.

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. Bring the liquid and the hydrometer to the other temperature to be used, and secure the composite correction as before. One portion contains only particles retained s the No. Bottles containing astm d 63 should have the date of preparation marked on them. Originally approved in Atm previous astm d 63 approved in as D — 63?
This set consists of the following sieves: Zstm PDF Download is licensed per individual in which the individual can place on up to four electronic devices for their personal use. Nominal Diameter of Largest Particles, in. When mechanical sieving is used, test the thoroughness of sieving by using the hand method of sieving as described above.
