EXAMPLE The item "Hex Cap Screw - A193 Grade B7,.250-20 X 1.250" appears in a manufacturer's catalogue. It can be described as:

Class: hexagon cap screw

Property values:

   [material specification, A193 Grade B7]

   [diameter, 0.250 in]

   [thread pitch, 20/in]

   [length, 1.250 in]

In actual characteristic data, the first element of each bracketed pair would be an identifier for a data dictionary entry. The elements are shown decoded here for clarity.
