The work o
10、f preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmenta

18、 1. The series itself describes the measures necessary to assure 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
19、 they should be applied for all of them. This Technical Report contains 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-sp
20、ecific parameters to be applied in these Technical Reports. This Technical Report is a first step. Contents will be supplemented step by step, and or even withdrawn due to newer technical or scientific expertise.

26、All aspects of a method shall be covered by test cases. It is to ensure that the test cases cover the main issues which can significantly affect results. These test cases are described with exact geometry, but generally with respect to parameters that might be different with different calculation me
27、thods. For the precisely defined test cases, according to A.2 in ISO 17534-1:, these general parameter descriptions can be concretized and supplemented by step-by-step results. 1) To be published.
