Type of transportation	Operation		Maximum acceleration (g)
			Up and down	Left and right	Front and back
Railway wagon	Vibration during operation (30∼ 60 km/h)		0.2∼0.6	0.1∼0.2	0.1∼0.2
	Vibration during deceleration		0.6∼1.7	0.2∼1.2	0.2∼0.5
Automobile	General highway	Good pavement	0.4∼0.7	0.1∼0.2	0.1∼0.2
	20∼40 km/h	Bad pavement	1.3∼2.4	0.4∼1.0	0.5∼1.5
	Paved highway	The full load	0.6∼ 1.0	0.2∼0.5	0.1∼0.4
