GB/T 23717.2-2009

This standard provides a classification system for vibration and shock levels within buildings that house sensitive equipment, such as laboratories, semiconductor fabrication facilities, or precision manufacturing plants. It is applied during the design, construction, or assessment of these structures to categorize the severity of dynamic disturbances and ensure they remain within acceptable limits for the installed equipment. The classification helps engineers and facility managers select appropriate vibration isolation measures and verify compliance with operational requirements.
