Schema documentation for component diggs:AggregateAbrasionValueTest

The Aggregate Abrasion Value is a measure of the resistance of aggregate to surface wear by abrasion. In this test, two specimens are pressed against the surface of a steel disc rotating in a horizontal plane, with a force of 0.365 newtons per sq. centimetre. Sand, fed by hoppers, is used as an abrasive. After 500 disc revolutions the amount of material abraded is measured by calculation of the weight loss of the aggregate. The percentage loss in mass of chippings as known as the ‘Aggregate Abrasion Value’ (AAV), and ranges from about 1 for hard flints to over 16 for aggregates normally considered too soft for use in road surfacings.

Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods. This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.
