What is BS EN 60654-2 - Power received by industrial-process measurement and control equipment about?

BS EN 60654 is a European standard that discusses operating conditions for industrial-process measurement and control equipment. BS EN 60654-2 is the second part of the multi-part series that outlines the limiting values for power received by land-based and off-shore industrial-process measurement and control systems or parts of systems, during operation. Maintenance and repair conditions are not considered. The influence quantities considered in BS EN 60654-2 are limited to those which may directly affect the performance of process systems. BS EN 60654-2 layouts limit values, or sets of limit values, for the operating conditions listed. Other operating conditions, including those for which characteristics are difficult both to define and to measure, and for which adequate standards are not known to exist, will be covered in other publications. An example of an operating condition difficult to define is corrosive atmospheres, which are difficult to classify due to the wide variety and concentration of corrosive substances and combinations of substances that may be encountered. Note 1: Only operating conditions as such are considered the effects of these conditions on instrumentation are specifically excluded. Note 2: Effects of the specific operating conditions on personnel are not within the scope of BS EN 60654-2 .
