Calculation according to VDI 2048

The guideline VDI 2048 describes the fundamental principles for evaluating acceptance measurements, including an assessment of promises of guarantee regarding the technical properties, for power plants based on statistical methods. A procedure for data validation that takes the requirements of this guideline into account is integrated into the software system  EBSILON^®Professional.

The fundamental principles of data validation are described in context in the guideline.

The following chapters contain an introduction into the theoretical foundations of VDI 2048.

• The mathematical formulation of the problem

• The Lagrange formalism

• Iteration procedure and treatment of auxiliary conditions

• Error messages, error analyses, and calculation of the covariances

• Raw data analysis

• Treatment of inequalities

• Ensuring monotonic convergence

• Treatment of table uncertainties

• Conversion to guarantee conditions
