BS EN 60654-4 is the fourth part of the BS EN 60654 multi-series that discusses operating conditions for industrial-process measurement and control equipment.
BS EN 60654-4 considers the corrosive and erosive industrial environment to which land-based and off-shore, industrial-process measurement and control systems or parts of systems may be exposed during operation, during periods when they are installed but inactive, during storage or transportation. The environmental influences considered in this part are limited to those which may directly affect the performance of process-measurement and control systems or parts of such systems.
Note: Maintenance and repair conditions are excluded from BS EN 60654-4.
BS EN 60654-4 on operating conditions for industrial-process measurement and control equipment is useful for:
Higher levels of contamination can occur permanently or temporarily. In many cases the effects on measurement and control equipment are proportional to the concentration, temperature and period of exposure, these effects being often increased by humidity. It is however very difficult to describe an environment by specifying the concentration of the contaminant against time.
BS EN 60654-4 provide you with a uniform listing and classification of corrosive and erosive environmental conditions to which equipment may be exposed in specified locations during operation, storage, handling and transportation.
BS EN 60654-4 helps you to minimize problems that might occur from neglecting considerations of specific operating conditions affecting the performance of systems and parts of systems.
Overall, the guidance of BS EN 60654-4 helps you to produce/design industrial process measurement and control equipment that are more resistant to corrosion and erosion influences.
