ISO 10816-7 classifies vibration levels into four "evaluation zones":

ISO 10816-7 defines four evaluation zones to assess the severity of vibration:

ISO 10816-7 is the international standard for evaluating mechanical vibration rotatable pumps

ISO 10816-7 is part of the ISO 10816 series of international standards, which provide guidelines for evaluating machine vibration by measuring on non-rotating parts, such as bearing housings. The full title of the document is "Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating parts — Part 7: Rotodynamic pumps for industrial applications, including measurements on rotating shafts". It is a first edition, published in February 2009, comprising 17 pages, and is currently designated as an International Standard that is "to be revised". iso 10816-7 pdf download

: Contains a shared copy of the standard (ISO 10816-7:2009) often used for engineering coursework.

Take initial baseline vibration velocity readings (usually measured in mm/s RMS) on the bearing housings in three orthogonal directions (horizontal, vertical, axial).

Applies to rotodynamic pumps for industrial use with power above 1 kW. : Contains a shared copy of the standard

To effectively use ISO 10816-7, it is important to understand several key terms and measurement principles defined within the standard.

To ensure compliance with ISO 10816-7, vibration analysts must follow strict measurement criteria: To effectively use ISO 10816-7, it is important

Measurements must cover a frequency range of at least 10 Hz to 1000 Hz to capture fundamental running speeds and common fault frequencies (like vane pass frequency).

Transducers (accelerometers) must be placed directly on, or as close as possible to, the bearing housing. Measurements are taken in three orthogonal directions: horizontal, vertical, and axial. Why Accessing the Official PDF Matters

The standard divides rotodynamic pumps into two distinct categories based on their critical power requirements and operational rigidity. Category I: High-Consequence Pumps

Machinery is unsatisfactory for long-term continuous operation. The pump may operate for a limited period until maintenance can be scheduled.
