Organization: IEC
Publication Date: 1 January 1983
Status: active
Page Count: 32
ICS Code (Industrial process measurement and control): 25.040.40
scope:

Part 3 of the standard considers the specific operating conditions of vibration, shock, seismic and mechanical stress conditions to which land-based, and off-shore, industrial-process measurement and control systems or parts of systems may be exposed during operation, storage or transportation. Maintenance and repair conditions are excluded from consideration in this Part 3.

The operating influences considered in this part are limited to those which may directly affect performance of process measurement and control systems. Effects of the specific operating conditions on personnel are not within the scope of this part. The appropriate values of the physical parameters listed here should be used to describe local environments in which equipment is expected to operate, be transported and stored. Only conditions as such are considered; the effects of these conditions on instruments' performance are specifically excluded.

IEC Publication 68: Basic Environmental Testing Procedures gives the basic test conditions for vibration and shock. This part establishes a list of selected limit values for the operating conditions.

Note. - Similar questions are at present being studied by Technical Committee No. 75: Classification of Environmental Conditions. Upon the issue of this committee's publication, the present publication should be reconsidered.

Object

The object of Part 3 of the standard is to provide users and suppliers of industrial-process measurement and control systems and parts of such systems with a uniform listing and classification of mechanical influences. The specified conditions to which equipment may be exposed during operation, storage, handling and transportation are included. Conditions for transportation are for equipment parts in suitable packages with appropriate locking and clamping devices to prevent damage, as well as for complete systems mounted in mobile units.

The listed operating conditions are intended to serve as a basis for comprehensive specifications.

One of the purposes of this part is to minimize problems which might result from neglecting considerations of specific operating conditions affecting performance of systems and parts of systems.

An additional purpose of this part is to aid the choice of specific limit values for use in the development of evaluation specifications for industrial-process measurement and control equipment.
