The paper analyses the implementation of European standards: PN-EN ISO 14688:2018 Geotechnical investigation and testing - Identification and classification of soil - Part 1: Identification and description and Part 2: Principles for a classification (hereinafter ISO) in Polish geotechnical practice. Although PN-EN ISO 14688 standards have been a part of the Polish standards scope since 2006, daily practice shows that their proper understanding and use still causes a lot of problems. On the basis of daily experience from reading archival geological and engineering reports and studies, the authors were able to indicate the most common issues in attempts to identify and describe soils according to the aforementioned ISO standards.

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 principles of identification and description of soil presented in the PN-EN ISO 14688-1:2018-05 standard are clear and easy to apply. The most important step in the identification process is the determination of the primary fraction in terms of plastic behaviour. The standard provides 8 tests to distinguish between silt and silt and clay as primary fractions determining the geological and engineering properties of soil.

Zbadano płytki posadzkowe z posadzki Wielkiego Refektarza z Zamku Średniego w Zespole Zamkowym z Malborka. Wykonane analizy makroskopowe oraz fizykochemiczne, pozwoliły uzyskać informacje odnośnie użytych mas i szkliw w produkcji płytek podłogowych. Wyniki badań stały się punktem wyjścia do opracowania nowych mas ceramicznych i szkliw o takiej samej kolorystyce barw, z podwyższeniem wytrzymałości na ścieranie.

In the research the floor tiles from the Great Refectory of the Middle Castle in Malbork were used. The executed macro- and microscopic analyses as well as a range of physical-chemical analyses made it possible to obtain information concerning the ceramic pastes and glazes used in producing the floor tiles. The obtained results became the starting point for creating new ceramic pastes and glazes of the same colour scheme, with a higher abrasion resistance.

The basic aim of our study was to design a physical model of a two-phase metal-matrix material which should be suitable both for computational simulation as well as for experimental verification of computations. To stimulate the matrix flow around the inclusions of the secondary phase, two different models have been designed; one was designed for deformations by tensile tests, and the other for more complex deformations due to the rolling process.
