Operating conditions for industrial-process measurement and control equipment - Part 3: Mechanical influences

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 - Maitenance and repair conditions are excluded from consideration in this Part 3 - The operating influcences 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 (Similar questions are at present being studied by Technical Committee 75: Classification of Environmental Conditions - Upon the issue of this committee's publication, the present publication should be reconsidered)
