Short description
The guideline describes typical infuences on the result of measurement of dimensional measurements with industrial Computertomografie (CT). In addition the different dimensional measuring tasks are classified, which can be realized using an industrial CT. In the annex of the guideline recommendations regarding the quality assurance of dimensional measurements with CT are given. Only axial CT-systems with a rotation of the examined workpiece around a space-fixed axle are considered. The rotation takes place orthogonal for radiography direction. Industrial CT-devices with x-ray tubes and line accelerators are regarded as the sources of x-ray. Further the structure of typical industrial CT-equipment, for which the indicated measured variables are valid are described. The descriptive factors of influence are valid thereby both for fan beam CT and for cone beam CT.
