Abstract: The Paper presents a new proposal of adjusting Polish soil classification in accordance with Polish Standard PN-B-02480:1986 to the nomenclature of Polish Standard PN-EN ISO 14688-1:2006. It has been demonstrated that Polish soil classification based on grain-size distribution and related to it visual and manual soil examination meets the requirements on rules and methods of soil identification in consistency with PN-EN ISO 14688:2006. It has been recommended that Polish soil classification should be used (after small changes, presented below) in PN-EN ISO 14688:2006 as a local Polish Enclosure to the said Standard. The proposal should be met with a favorable reception by civil engineers as it allows for implementation of PN-EN ISO 14688-1:2006, and in the same time it follows the concept that the engineers have been used to for many years.
