ISO 10816 operates with the term vibration magnitude, which, depending on the machine type, can be an RMS value of vibration velocity, acceleration or displacement. ISO 10816 keeps the lower frequency range flexible between 2 and 10 Hz, depending on the machine type. Machine condition is generally diagnosed on the basis of broad band vibration measurements returning an RMS value. Features of ISO 10816 Measurements are made in three direction (horizontal, vertical, axial). There are two ISO recommendations concerning machine condition monitoring by this type of measurement, the much used ISO 2372 and the more recent ISO 10816, which is a replacement of the older standard.
Broad band vibration measurement is the most widely used and cost-efficient method for the diagnosis of general machine condition.
