- This International Standard defines methods of meas-uring and reporting shock and vibration data for shock-and vibration-sensitive equipment (in operating and non-operating modes) in buildings. The shock and vi-bration data obtained are used to establish a database.
To facilitate comparison of data (e.g. comparison of shock and vibration levels measured in different coun-tries on equipment from different manufacturers), a database reporting system is discussed. The reporting system presented will aid in the establishment of lim-iting values for specific equipment and also for classi-fication of their environmental conditions.
The types of shock and vibration considered in this In-ternational Standard are those transmitted from floors, tables, walls, ceilings or the isolation system to a unit of equipment. The vibration and shock response of individual mechanical or electronic parts inside the unit are not considered.
The classification system of environmental conditions established from the database should serve as a guide for those who construct, manufacture and use shock-and vibration-sensitive equipment and for building contractors. The types of sensitive equipment envis-aged include:
a) stationary computer systems (including the peri-pherals);
b) stationary telecommunication equipment;
c) stationary laboratory instruments, such as elec-tron microscopes, mass spectrometers, gas chromatographs, lasers and X-ray apparatus of general character;
d) mechanical high-precision instruments (tools), such as equipment for microelectronic produc-tion;
e) optical high-precision instruments, photo-repro-duction instruments and E-beams;
f) electromechanical systems in train traffic control centres;
g) security equipment (fire detection) and equipment for access control.
The types of shock and vibration considered in this International Standard can be generated by:
a) external sources (e.g. traffic or building and con-struction activities such as blasting, piling and vi-bratory compaction); the vibration response to sonic booms and acoustic excitations is also in-cluded;
b) equipment for indoor use, such as punch presses, forging hammers, rotary equipment (e.g. air com-pressors, air-conditioner pumps) and heavy equipment transported or operated inside a
building;
c) human activities in connection with the service or operation of the equipment;
d) natural sources, such as earthquakes, water and wind;
e) internal sources; i.e. vibration generated by the equipment itself.
The frequency range of interest is 0,5 Hz to 250 Hz. (The frequency range of interest for earthquake-induced vibration is 0,5 Hz to 35 Hz.) Normally the dominant frequencies are less than 100 Hz, because
they represent the response of the elements of the building.
The vibration amplitude and duration depend mainly upon the source, its distance from the sensitive equip-ment and the response of the elements of the build-ing supporting the sensitive equipment. Expressed in terms of particle velocity, which is the parameter used currently in building vibration evaluation, the values are in the range of 10
m/s to 2 × 10 m/s. The vibration values of interest for transient and con-tinuous vibration from different sources are given for information in annex B.
