[REQUEST] ASTM Standards Request

[devilmaycry]

Hi guys, I need the following standards, thanks in advance:

ASTM D4959 - 07 Standard Test Method for Determination of Water (Moisture) Content of Soil By Direct Heating

ASTM D2419-09 Standard Test Method for Sand Equivalent Value of Soils and Fine Aggregate, 2009

ASTM D4959-07 Standard Test Method for Determination of Water (Moisture) Content of Soil By Direct Heating

Author: ASTM Committee D18 | Size: 0.1 MB | Format: PDF | Quality: Original preprint | Publisher: ASTM Int. | Year: 2007 | pages: 6

1.1 This test method covers procedures for determining the water (moisture) content of soils by drying with direct heat, such as using a hotplate, stove, blowtorch, etc.
1.2 This test method can be used as a substitute for Test Methods D2216 when more rapid results are desired to expedite other phases of testing and slightly less accurate results are acceptable.
1.3 When questions of accuracy between this test method and Test Methods D2216 arise, Test Methods D2216 shall be the referee method.
1.4 This test method is applicable for most soil types. For some soils, such as those containing significant amounts of halloysite, mica, montmorillonite, gypsum, or other hydrated materials, highly organic soils or soils that contain dissolved solids, (such as salt in the case of marine deposits), this test method may not yield reliable water content values.
1.5 The values stated in SI units are to be regarded as standard.
1.6 Refer to Practice D6026 for guidance concerning the use of significant figures. This is important if the water content will be used to calculate other relationships such as moist mass to dry mass or vice versa, wet unit weight to dry unit weight or vice versa, and total density to dry density or vice versa. For example, if four significant digits are required in any of the above calculations, then the water content has to be recorded to the nearest 0.1%. This occurs since 1 plus the water content (not in percent) will have four significant digits, While, if three significant digits are acceptable, then the water content can be recorded to the nearest 1%
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D2419 – 09 Standard Test Method for Sand Equivalent Value of Soils and Fine Aggregate

Author: ASTM Committee D04 | Size: 0.32 MB | Format: PDF | Quality: Original preprint | Publisher: ASTM Int. | Year: 2009 | pages: 9

1.1 This test method is intended to serve as a rapid fieldcorrelation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-like or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve. The term “sand equivalent” expresses the concept that most granular soils and fine aggregates are mixtures of desirable coarse particles, sand, and generally undesirable clay or plastic fines and dust.
NOTE 1—Some agencies perform the test on material with a top size smaller than the 4.75-mm (No. 4) sieve. This is done to avoid trapping the clay-like or plastic fines and dust below flaky shaped 4.75 to 2.36 mm (No. 4 to 8) sized particles. Testing smaller top sized material may lower the numerical results of the test.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only
and are not considered standard.
1.2.1 Regarding sieves, per Specification E11 Section 1.2, “the values stated in SI units shall be considered standard for the dimensions of the wire cloth openings and the diameter of the wires used in the wire cloth. The values stated in inchpound units shall be considered standard with regard to the sieve frames.” When sieve mesh sizes are referenced, the alternate inch-pound designations are provided for information purposes and enclosed in parentheses.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
