It is intended that this part of ISO 17892 p
36、resents broad good practice and significant differences with national documents is not anticipated. It is based on international practice (see Reference 1).DIN EN ISO 17892-3:2016-07 EN ISO 17892-3:2015 (E)6 1 ScopeThis part of ISO 17892 specifies methods for the determination of the particle densit
37、y of soils.This part of ISO 17892 is applicable to the 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 metho
38、d described in this part of ISO 17892 applies to soil 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 sp
39、ecimen container of the particular gas pycnometer being 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 po
40、re water can affect the results of these tests. Techniques 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 applic
