BS EN 61298-2 is the second part of the IEC 61298 multi-series that discusses process measurement and control devices.
BS EN 61298-2 specifies general methods and procedures for conducting tests and reporting on the functional and performance characteristics of process measurement and control devices.
The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs, and include analogue and digital devices. For devices that require special tests, BS EN 61298-2 should be used, together with any product-specific standard specifying special tests.
BS EN 61298-2 covers tests made under reference conditions.
BS EN 61298-2 on general methods and procedures for evaluating the performance of process measurement and control devices is useful for:
Process measurement and control devices measure and regulate the conditions such as humidity, airflow, pressure etc. Given the conditions these devices operate in their operating efficiency can get affected over a period of time. Hence, these devices need to be regularly evaluated to verify their performance.
The guidelines of BS EN 61298-2 help you to perform tests on process measurement and control devices under reference conditions. BS EN 61298-2 helps you to identify the dynamic performance, and general characteristics of control devices which includes input resistance, insulation, power consumption and airflow characteristic of a pneumatic device. BS EN 61298-2 also helps you to perform tests to calculate the start-up drift and long-term drift of the measurement and control devices.
Overall, the guidelines of BS EN 61298-2 enable you to verify that your process measurement and control devices are performing to the specified level.
