Zone B indicates that the machine is operating within acceptable limits for long-term continuous operation. However, the vibration levels are higher than a "new" machine. iso 10816-3 vibration severity chart
: These machines use isolators (like springs or rubber mounts) and are allowed higher vibration limits as the mounting absorbs some of the dynamic forces. For example, a Group 2 machine on a rigid foundation typically enters (alert level) when vibration exceeds 2.8 mm/s RMS vibromera.eu : ISO 10816-3 has been formally superseded by ISO 20816-3 For more detailed technical specifications, you can refer
