Scope Part 4 of the standard considers the corr

36、osive 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. Maintenance and repair conditions

37、 are excluded from this part. The environmental influences considered in this part are limited to those which may directly affect performance of process-measurement and control systems or parts of such systems. Effects of the specific environmental conditions on personnel are not within the scope of

38、 this part. The appropriate values of the physical or chemical parameters listed here as well as the qualitative descriptions of the environment should be used to define local environments in which equipment is expected to operate, be transported and stored. Only conditions as such are considered; t

39、he resulting effects of these conditions on instrument performance are specifically excluded. Many environmental conditions listed in this part are difficult to classify so that a qualitative description is used to characterize the environment. 2. Object The object of Part 4 of the standard is to pr

40、ovide users and suppliers of industrial-process measurement and control systems and parts of such systems 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 trans

41、portation. Condi- tions for transportation are for equipment in suitable packages to prevent damage. The listed environmental conditions are intended to serve as a basis for comprehensive specifications. One of the objects of this part is to minimize problems which might result from neglecting considerations of specific operating conditions affecting performance of systems and parts of sys tems. An additional object of this part is to aid in the choice of specific limit values for use in the development of evaluation specifications for industrial-process measurement and control equipment.
