The purpose is based on the characteristics of in vitro diagnostic medical equipment and Electromagnetic environment, specifies the basic requirements for its electromagnetic compatibility immunity and emission. --- Part 31.Immunity requirements for safety-related systems and equipment intended to perform safety-related functions (functional safety) for general industry application. The purpose is to specify the expected performance of SIL1 to SIL3 in IEC 61508 in the electromagnetic environment of indoor and outdoor industrial sites Immunity requirements for industrial systems and equipment for safety functions. --- Part 32.Immunity requirements for safety-related systems and equipment intended to perform safety-related functions (functional safety) Industrial applications in magnetic environments. The purpose is to specify the specific electromagnetic environment resulting from the use of mitigation measures in indoor and outdoor industrial sites Immunity of systems and equipment for industrial applications intended to perform safety functions as specified in IEC 61508 SIL1 to SIL3 degree requirements. Functional safety is part of the overall safety of the equipment under control (EUC) and EUC control systems that rely on electrical safety the correct operation of the relevant system. To achieve this goal, all equipment components involved in safety-related systems performing safety functions can be Work in the prescribed manner under relevant conditions. GB/T 20438 is the basic safety standard for functional safety of electrical/electronic/programmable electronic safety-related systems. it specifies the implementation All requirements for functional safety. Adequate electromagnetic disturbance immunity is one of the requirements. In the concept of GB/T 20438, the consideration of application and the design of electrical and electronic safety-related systems are distinguished. "Overall Safety Requirements" Specification (SSRS) specifies all relevant requirements for the intended application, as follows. a) The definition of functional safety is based on a risk assessment of the intended application whose function is to reduce risk. b) The appropriate Safety Integrity Level (SIL) for each safety function is based on the risk assessment of the intended application. c) The environment (including electromagnetic environment) in which the system is expected to work is defined in accordance with the requirements of GB/T 20438. The requirements for each safety function are specified in one or more System Safety Requirements Specifications (SSRS). Therefore, according to GB/T 20438 requires that considering the immunity of electromagnetic phenomena, the electromagnetic environment and electromagnetic phenomena are first considered in SSRS. Safety-related systems used to perform specified safety functions should meet SSRS, and their corresponding immunity levels should be based on the equipment department. The requirements specification of the equipment itself; these conclusions should be issued in the equipment requirements specification. Regarding the electromagnetic environment, SSRS and equipment requirements regulations are to be established An accurate assessment of the actual electromagnetic environment that the equipment may be exposed to throughout the foreseeable life cycle. Therefore, the immunity requirements of the equipment should be taken as Depends on the characteristics of the electromagnetic environment in which the equipment is intended to be used. Therefore, equipment manufacturers can use appropriate methods to demonstrate that their equipment meets equipment requirements specifications, while system integrators can demonstrate Its system complies with the requirements of SSRS. They do not need to consider other aspects of the application, e.g. application risk related to failure of safety-related systems risk. Its purpose is to make all equipment in the system comply with the special performance criteria for functional safety (such as the performance criterion DS) The level specified by SSRS, regardless of the SIL level. See Appendix A for a method on how to apply the IEC 61326-3 series of standards. The general EMC standard is applicable to a given electromagnetic environment, as well as those that have not yet formulated a special series of product EMC standards/product EMC standards product. However, for equipment within the scope of this document, the information provided in the general EMC standard is not sufficient. need to give more details Information and specifications, such as specific test configurations, take into account functional earth ports or the type of electromagnetic environment associated with the equipment within the scope of this document. difference.
