New or newly commissioned machinery. Vibration levels are within acceptable, optimal ranges.

Primarily focuses on vibration measurements made on non-rotating parts, such as bearing housings .

: Pumps requiring high reliability, availability, or safety (e.g., hazardous toxic liquids, critical power plant pumps). iso 10816-7 pdf download

This category enforces stricter (lower) allowable vibration thresholds due to the high energy and risk involved. Category II: Standard Industrial Pumps

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). New or newly commissioned machinery

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".

However, if the motor is connected via a flexible coupling, the standard only applies to the pump itself. Separately mounted drivers are explicitly excluded and are covered by other standards like ISO 10816-3. : Pumps requiring high reliability, availability, or safety

ISO 10816-7 establishes specific procedures and guidelines for assessing the mechanical vibration of rotodynamic pumps for industrial applications. It applies to measurements taken on the non-rotating parts, such as the bearing housings of the pumps. Key Metrics Covered
