The series itself describes the measures necessary to assure

18、 a high quality calculation methods implemented in different software products with respect to correctness and precision. The requirements and specifications included are obviously independent from a specific calculation method, because they should be applied for all of them.This Technical Report co

19、ntains generally applicable recommendations to be taken into account in the formulation of such recommendations in the method-specific Technical Reports. Further, a set of test cases is presented that can be supplemented with method-specific parameters to be applied in these Technical Reports.This T

20、echnical Report is a first step. Contents will be supplemented step by step, and or even withdrawn due to newer technical or scientific expertise.Figure 1 Structure of the ISO 17534 series consisting of the main Part 1 and subordinated Technical Reports ISO 2014 All rights reserved vPD ISO/TR 17534-
