Standard Test Method, European Committee for Standardization Part 3: Design Assisted by Field Testing, Section 9: FLAT DILATOMETER TEST (DMT), 9 pp. TC16 (1997). “The DMT in soil Investigations”, a report by the ISSMGE Technical Committee tc16 ON Ground Property, Characterization from in-situ testing, 41 pp. ASTM (2002). Standard Test Method D , American Society for Testing and Materials The standard test method for performing the Flat Dilatometer Test (DMT), 14 pp. FLAT DILATOMETER
