An object describing a flat plate dilatometer test procedure. This testconsists of forcing the dilatometer blade into the soil, with the membrane facingthe horizontal direction, to a desired test penetration, measuring the thrust toaccomplish this penetration and then using gas pressure to expand a circular steelmembrane located on one side of the blade. The operator measures and records thepressure required to produce expansion of the membrane into the soil at two presetdeflections. The operator then deflates the membrane, possibly recording an optionalthird measurement, advances the blade the desired penetration increment and repeatsthe test.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
