International organizations, governmental and non-governmental, in liaison with ISO, also take part in th

In particular the
22、different approval criteria needed for the different types of ISO documents should be noted.

33、:2015INTERNATIONAL STANDARD ISO 17892-3:2015(E)Geotechnical investigation and testing Laboratory testing of soil Part 3: Determination of particle density1 ScopeThis part of ISO 17892 specifies methods for the determination of the particle density of soils.This part of ISO 17892 is applicable to the
34、 laboratory determination of the particle density of soil within the scope of geotechnical investigations, and describes two methods, a pycnometer method by fluid displacement and a pycnometer method by gas displacement.The fluid pycnometer method described in this part of ISO 17892 applies to soil
35、types with particle sizes under about 4 mm, or soils crushed to meet this requirement. Larger pycnometers are used for coarser materials. The particle size of soils suitable for testing in the gas pycnometer is limited by the dimensions of the specimen container of the particular gas pycnometer bein
36、g used.NOTE 1 This part of ISO 17892 fulfils the requirements of the determination of particle density of soils for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.NOTE 2 The presence of dissolved salts in the pore water can affect the results of these tests. Techni
37、ques for compensating for dissolved salts are available but are beyond the scope of this standard.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

41、dicating desiccant such as silica gel. It is not required if test specimen containers with close-fitting lids are used.NOTE The purpose of the desiccator is to prevent absorption of moisture from air.4.2.3 Riffle box, should be used to obtain a representative part of the specimen. Distribution by ha

Any air circulation shall not be so strong that any transport of particle
43、s can take place.4.2.5 Sample crushing equipment, a mortar and soft-ended pestle (e.g. a pestle with a rubber or wooden tip) shall be used to break up dried soil specimens. More substantial sample crushing equipment may be required to crush gravel sized rock particles.4.3 Fluid displacement equipmen

48、 is required to fill the pycnometer bottle. Distilled, demineralized, or deionized water is often the most suitable liquid. Alternatively, a suitable organic solvent such as hexane or kerosene may be used. Control liquids with a surface tension lower than that of water might be found to be preferabl
