Standard Test Method for Determination of Water (Moisture) Content of Soil by the Microwave Oven Method
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method outlines procedures for determining the water (moisture) content of soils by incrementally drying soil in a microwave oven.
1.2 This test method is not intended as a replacement for Test Method D2216; but, rather as a supplement when more rapid results are required or desired to expedite other phases of testing. Test Method
1.3 When questions of accuracy between this test method and Test 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 in which the pore water contains 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 the standard.
1.6 This standard does not purport to address all of the safety problems, 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. See Section 7.
Note 1-Notwithstanding statements of precision and bias contained in this standard, the precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies that meet the criteria of PracticeKeywords
