IEC/TS 62098:2000 pdf download-Evaluation methods for microprocessor- based instruments.
1 General 1.1 Scope This Technical Specification aims at providing background information for developing evaluation methods for microprocessor-based instruments. An evaluation starts with analysis of the instrument in terms of the external and internal information flows from and to the process, the human operator and external systems. Main function blocks in the instrument are then identified. By using the checklists given in 4.2 and 4.3, the functions and properties that may be embedded in the function blocks of the instrument to be evaluated can be identified. Subclause 4.4 gives a checklist for identification of the relevant influencing conditions for the instrument to be evaluated. Depending on the application of an instrument, the user of this technical specification may have to define further functions and properties or influencing conditions.
