This part of IEC 62765 provides strategies, technical requirements, and recommended practices for the management of ageing to ensure that ageing of pressure transmitters important to safety in nuclear power plants (NPPs) can be identified and that suitable remedial actions are undertaken as necessary to demonstrate that the safety of the plant will not be impaired. This standard is aligned with the IEC 62342 standards, which provides guidance on ageing management for I&C systems important to safety in NPPs. This standard, IEC 62765-1 , is the first part for pressure transmitters in the IEC 62765 sensor and transmitter series for pressure, temperature, neutron and other sensors. This standard deals with analogue electronic pressure transmitters, which have an electrical signal output that is a function of pressure applied on the sensing part, and which are included in I&C systems important to safety in accordance with IAEA terminology. Any software used for data acquisition, data qualification, or data analysis for transmitter testing or condition monitoring system for pressure transmitter is classified according to IEC 62138 depending on its functionality as specified in IEC 61226 . The qualification of the software for the digital data processing is beyond the scope of this standard. Additional condition monitoring system for ageing management of the pressure transmitters is classified according to IEC 61226 with respect to its functionality. If classified, the software installed in the monitoring system complies with IEC 62138 for its B or C categorised function. Regarding environmental qualification, the requirements of IEC 60780 apply. For assessing the performance of transmitters in the safety system instrument channel, the IEC 62385 methods, IEC 61888 requirements and IEC 60671 surveillance testing requirements apply. Pressure measurements may be used for the measurement of other parameters that can be related to pressure, e.g., level or flow. Interfaces which include sensing lines, condensing pots, and primary (e.g., flow) elements between process and transmitters are within the scope of this standard.
