The article introduces the methods of identification, description and classification of soils presented in the PN-ENISO14688-1 and PN-EN ISO 14688-2 standards. Experience shows that these standards, although referred to by Eurocode 7, are still not fully implemented and are most often applied incorrectly. In practice, the soil is still identified macroscopically using the principles presented in the with drawn PN-B-02480:1986, PN-B-02481:1998 and PN-B-04481:1988 standards.

The paper presents classifications of seven different cohesive soils, based on seven methods suggested by the standards PN-B-02480:1994, PN-B-04481:1988 and PN-EN ISO 14688:2006. Two included macroscopic analysis, three - grain distribution and two other - Atterberg limits. The liquid limits, necessary to determine the soil type according to the Casagrande's nomogram, were assessed with the use of the Casagrande's method according to PN-B-04481:1988 and cone penetrometer test according to PKN-CEN ISO/TS 17892-12:2009. The latter one gave lower values, which is consistent with previous studies. The results were additionally evaluated in terms of the activity and swelling potential of the soils. It has been concluded that macroscopic analysis classifies soils in a way similar to the one suggested in the Casagrande’s nomogram, which in turn, allows estimation ofphysical parameters of the cohesive soils. In the Authors'opinion, these two ways of cohesive soil description are worth using; the necessity ofplotting the grain size distribution curves could be limited to some doubtful cases - e.g. when the activity value of soil is required.

The paper illustrates principles of soil classification system according to PN-EN ISO 14688 and critical remarks concerning it. Differences between both classifications PN-86/B-02480 and PN-EN ISO have been emphasized. In the era of globalization it is essential that technical standards like those for the classification of soil types, are uniform. The ISO classification presented in the paper stresses the recognition of soil type with its characteristics influencing its mechanical features such as fractions, grain size and shape, sustainability.
