ISO 10816-7 is a vital international standard for engineers focusing on the reliability of rotodynamic pumps in industrial settings. It provides the framework for assessing machine health through vibration measurements on non-rotating parts, like bearing housings. The Scope of ISO 10816-7 The standard specifically addresses rotodynamic pumps
for industrial applications with a nominal power above 1 kW. It defines the requirements for evaluating vibration levels measured on non-rotating parts, primarily the bearing housings, during both in-situ operations and factory acceptance tests. While its primary focus is on non-rotating components, it also provides supplemental guidance for measuring relative shaft vibration. ISO - International Organization for Standardization Core Evaluation Criteria
The standard employs two main criteria to judge the severity of machine vibration: Absolute Magnitude:
Comparing the overall root-mean-square (r.m.s.) vibration velocity (measured in mm/s) against predefined thresholds. Change in Magnitude: iso 10816-7 pdf download
Assessing significant shifts in vibration levels from a baseline, which often indicates developing faults even if absolute limits haven't been reached. Machine Categorization and Zones
ISO 10816-7 classifies pumps into two categories based on their criticality: ИС «МЕГАНОРМ» Category I:
High-reliability pumps used for toxic or hazardous liquids (e.g., in nuclear or chemical plants). Category II: General-purpose pumps for less critical applications. Health is categorized into four "Evaluation Zones": ИС «МЕГАНОРМ» Vibration of new machines (excellent). Suitable for long-term continuous operation (acceptable).
Unsuitable for long-term operation; limited runtime until maintenance (unsatisfactory).
Risk of serious damage; immediate action required (unacceptable). Accessing the Standard

ISO 10816-7 is the international standard specifically governing the mechanical vibration of centrifugal pumps for industrial applications. It defines the procedures and guidelines for measuring and evaluating vibration on non-rotating parts (like bearing housings) during steady-state operation. Overview of ISO 10816-7
This standard provides distinct criteria for assessing vibration levels based on the pump's power, reliability requirements, and installation type. It is widely used by maintenance engineers and plant operators to ensure equipment longevity and safety.
Scope: Covers centrifugal pumps for industrial use with nominal power above 1 kW.
Measurement Metrics: Focuses on vibration velocity (expressed in mm/s or in/s RMS). This metric is the best indicator of the overall "energy" of the vibration and its potential to cause structural fatigue. Pump Categorization:
Category I: Pumps requiring high reliability, availability, or safety (e.g., hazardous toxic liquids, critical power plant pumps).
Category II: General-purpose industrial pumps where downtime is less critical. Vibration Evaluation Zones
The standard classifies vibration severity into four colored zones, which help in deciding the necessary maintenance action: The official standard ISO 10816-7:2009 , which specifies
Zone A (Green): Vibration of newly commissioned machines; considered excellent.
Zone B (Yellow): Machines considered acceptable for unrestricted long-term operation.
Zone C (Orange): Machines considered unsatisfactory for long-term continuous operation; remedial action should be planned.
Zone D (Red): Vibration levels are high enough to cause immediate damage; the machine should be shut down. How to Access the PDF
International standards are copyrighted documents. You can legally obtain the full ISO 10816-7:2009 (or its latest version) through the following official channels:
ISO Store: The official ISO.org website offers the PDF for purchase and immediate download.
National Standards Bodies: Organizations like ANSI (USA), BSI (UK), or DIN (Germany) provide localized versions (e.g., BS ISO 10816-7).
IHS Markit/Techstreet: These are authorized commercial resellers used by many engineering firms for standards subscriptions. Technical Importance
Using ISO 10816-7 allows for a standardized language between pump manufacturers and end-users. Instead of subjective "feel," it provides empirical limits that help prevent catastrophic bearing failures, seal leaks, and shaft issues.

True for most pumps. However, for very slow-speed pumps (< 600 rpm), displacement (µm) may be more appropriate—but ISO 10816-7 does not cover those speeds.

⭐⭐⭐⭐⭐ "Exactly what I needed for a pump vibration audit. Downloaded in seconds, fully searchable."
— Carlos M., Reliability Manager
⭐⭐⭐⭐⭐ "Saved hours of searching. Clear tables for zone limits based on pump type and support stiffness."
— Dr. Li Wei, Condition Monitoring Specialist
The standard divides pump vibration severity into four zones:
| Zone | Description | Action | |------|-------------|--------| | A | Good (newly commissioned) | No action needed | | B | Acceptable for long-term operation | Monitor normally | | C | Unsatisfactory – may cause damage | Schedule maintenance | | D | Unacceptable – immediate action required | Shutdown and repair |
Limits depend on pump type (e.g., vertical vs. horizontal), power rating, and mounting stiffness.
ISO 10816-7:2009 (the latest version) is titled: "Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating parts — Part 7: Rotodynamic pumps for industrial applications, including measurements on rotating shafts."
This standard applies to:
It does not cover reciprocating pumps, submersible pumps, or pumps for hydraulic power systems.
