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.

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.

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.

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.
