26、:2014 (E) 3 IntroductionThis document covers areas in the international field of geotechnical engineering never previously standardised internationally. It is intended that this document presents broad good practice throughout the world and significant differences with national documents is not anti

27、cipated. It is based on international practice (see Reference 1).DIN EN ISO 17892-2:2015-03 EN ISO 17892-2:2014 (E) 4 1 ScopeThis International Standard specifies three methods for the determination of the bulk density of soils, comprising:a) linear measurement method;b) immersion in fluid method;c)

28、 fluid displacement method.This International Standard is applicable to the laboratory determination of the bulk density of soil within the scope of geotechnical investigations.The linear measurement method is suitable for the determination of the bulk density of a specimen of soil of regular shape,

29、 including specimens prepared for other tests. The specimens used are either rectangular prisms or cylinders with circular cross sections.The immersion in fluid method covers the determination of the bulk density of a specimen of natural or compacted soil by measuring its mass in air and its apparen

30、t mass when suspended in fluid. The method may be used when lumps of material of suitable size can be obtained.The fluid displacement method covers the determination of the bulk density of a specimen of soil by measuring its mass in air and the mass of fluid displaced by immersion. The method may be

31、 used when lumps of material of suitable size can be obtained.If the immersion in fluid method or fluid displacement method is used, and if the fluid is likely to penetrate into the specimen (eg water) the specimen should be coated before testing to prevent fluid penetration.The bulk density of a so

32、il is useful in the determination of the in situ overburden stress as a function of depth.If required, the dry density of a specimen may be calculated from the bulk density and the water content, if known.NOTE This International Standard fulfils the requirements of the determination of the bulk dens

33、ity of soils for geotechnical investigation and testing in accordance with EN 19971 and EN 19972.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、 straight edge, with a maximum deviation from straight of 0,1 % of its length.4.1.3 Try-square or a jig (e.g. a mitre box) or split mould, to ensure that flatness shall be accurate to within 0,5 % of each dimension and that right-angles are within 0,5 of true.4.1.4 Callipers, either analogue or digi

The container shall be large enough to accommodate the specimen.4.3.2 Container, to collect the fluid siphoning

43、.g. paraffin wax).4.3.6 Equipment for melting wax (if used), preferably electrically heated and thermostatically controlled.Alternatively, the equipment described in 4.2 can be used. In such case, a correction for the uplift for the cradle shall be included in the calculations.5 Test procedureTest s

44、pecimens should be at least 50 cm3in volume, and preferably significantly larger.NOTE If smaller specimens are tested they may be less representative of the material as a whole and the result may not be as accurate as suggested by the reported value.5.1 Linear measurement method5.1.1 GeneralThe prin

45、ciple of the method is to weigh a specimen of known volume. Three procedures are specified for preparing the specimen. Other methods are also accepted if they provide representative specimens of regular shape.5.1.2 Specimen from block sample5.1.2.1 At least 10 mm from the outside face of the block s

46、ample shall be cut away and an approximately rectangular prism of soil slightly larger than the final dimensions of the specimen shall be formed. If the specimen is to be used for some other test, its shape and dimensions shall also be appropriate for that test.5.1.2.2 For a rectangular prism specim

47、en the faces shall be made plane and parallel by careful trimming and checking with a straight edge and try-square or other jig.
