Searching for “ISO 10816-7 PDF download” is the first step toward better pump reliability. While there’s no legal free lunch, the official document is a worthwhile investment compared to the cost of a catastrophic pump failure. Use the standard alongside vibration analyzers and root cause analysis to keep your rotodynamic pumps running in Zone A or B.

The ISO 10816-7:2009 standard is the essential global benchmark for evaluating the mechanical vibration of rotodynamic pumps. Whether you are a reliability engineer or a maintenance manager, understanding how to apply these criteria is critical for ensuring pump longevity and preventing catastrophic failures. What is ISO 10816-7?
ISO 10816-7 provides specific instructions for evaluating vibration measured on non-rotating parts, such as bearing housings, for industrial rotodynamic pumps with a nominal power above 1 kW.
Unlike more general standards, this part of ISO 10816 is tailored specifically to the unique hydraulic and mechanical characteristics of pumps. It covers both horizontal and vertical pumps and is used for: Operational monitoring of pumps in situ. Factory acceptance tests at the manufacturer's facility. Setting Alarm and Trip thresholds to prevent damage. Key Measurement Parameters
To comply with the standard, measurements must follow these technical requirements:
Primary Quantity: The root-mean-square (r.m.s.) vibration velocity in mm/s.
Frequency Range: Typically 10 Hz to 1,000 Hz. For low-speed pumps (below 600 r/min), the range should extend down to 2 Hz, and peak-to-peak displacement ( ) must also be measured.
Pump Categories: The standard distinguishes between two main application types:
Category I: Pumps for high-reliability or critical applications (e.g., hazardous liquids, chemical, or power plants).
Category II: Pumps for general or less critical industrial applications. Evaluation Zones and Limits
ISO 10816-7 classifies vibration levels into four "evaluation zones":
Zone A: Vibration of newly commissioned machines (typically within the preferred operating range).
Zone B: Machines considered acceptable for unrestricted long-term operation.
Zone C: Machines considered unsatisfactory for long-term continuous operation, though they may operate for a limited period until maintenance can be performed.
Zone D: Vibration levels high enough to cause immediate damage to the machine. 1st ISO/CD 10816-7 "Mechanical vibration

This standard provides instructions for evaluating the vibration of rotodynamic pumps for industrial applications. Scope: Applies to pumps with nominal power above 1 kW.
Measurements: Primarily focuses on vibration measurements made on non-rotating parts, such as bearing housings.
Applications: Used for in-situ operational monitoring, factory acceptance tests, and general diagnostics.
Classification: Distinguishes between pumps above and below 200 kW for certain evaluation criteria.
Current Status: The 2009 version remains the current standard, though a successor (ISO 20816-7) is currently under development. Evaluation Zones
The standard classifies vibration severity into four zones to help engineers determine machine health:
Zone A: Vibration of newly commissioned machines (excellent). Zone B: Acceptable for unrestricted long-term operation. Zone C: Acceptable for limited operation only. Zone D: Dangerous levels; risk of damage to the machine. Where to Purchase and Download ISO 10816-7:2009 - Mechanical vibration

The standard classifies vibration severity into four distinct zones to guide maintenance decisions:
Zone A: Vibration typical of newly commissioned machines in the preferred operating range.
Zone B: Machines normally considered acceptable for unrestricted long-term operation.
Zone C: Vibration levels considered unsatisfactory for long-term continuous operation; maintenance should be planned.
Zone D: High vibration levels that carry a significant risk of immediate damage; the pump should be shut down. Measurement Requirements

ISO 10816-7 standard provides specific guidelines for evaluating the mechanical vibration of rotodynamic pumps for industrial applications with a nominal power above
kW. It focuses on measurements taken on non-rotating parts, such as bearing housings, and also includes guidelines for rotating shafts. ISO - International Organization for Standardization Key Features of ISO 10816-7 Vibration Severity Zones
: The standard classifies vibration severity into four distinct zones to assess machine health: : Typical of newly commissioned machines [5.2]. : Acceptable for long-term continuous operation [5.2].
: Unsatisfactory for long-term use; usually requires a planned shutdown for remedial action [5.2].
: Dangerous levels likely to cause immediate damage to the pump [5.2]. Dual Evaluation Criteria
: It uses two primary criteria for assessing vibration during long-term operation: Absolute Magnitude
: Comparing the measured vibration value against defined zone boundaries. Change in Magnitude
: Monitoring significant deviations from established baseline values, even if they remain within "acceptable" zones. Support & Orientation Flexibility
: Unlike other parts of the ISO 10816 series, Part 7 specifies limits for both horizontal and vertical pumps regardless of their support flexibility (rigid vs. flexible). Pump Categorization
: It distinguishes between two pump categories based on their criticality: Category I
: Pumps with high requirements for reliability and safety (e.g., handling hazardous or toxic liquids) [5.1]. Category II
: Standard industrial pumps for less critical applications [5.1]. Measurement Quantities Velocity (mm/s RMS) : The primary measurement for most industrial pumps [3.1]. Displacement ( m peak-to-peak) : Used specifically for low-speed pumps (operating below Frequency Ranges : Typically monitors a wide frequency band from Hz, though lower-speed machines require starting at Hz to capture rotation-related components.
