ISO 10816-7-2009 PDF

Full title and description

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 part of ISO 10816 gives guidance for assessing vibration measured on non-rotating parts (typically bearing housings) of rotodynamic pumps used in industrial applications (nominal power above 1 kW), and includes notes on corresponding shaft measurements and acceptance testing.

Abstract

ISO 10816-7:2009 provides instructions for the evaluation of vibration on rotodynamic pumps for industrial use. It defines measurement locations, measurement quantities and evaluation criteria when vibration measurements are taken on non-rotating parts (bearing housings) and gives guidance for acceptance tests at the manufacturer's facility and for in-service monitoring. The standard addresses assessment by overall vibration values and trends and recommends procedures for setting operational limits, alarm and trip values to help ensure reliable long‑term pump operation and to minimise transmitted vibration to connected equipment.

Scope

The standard applies to rotodynamic pumps for industrial applications with nominal power above 1 kW. It covers procedures and requirements for measuring and evaluating vibration on non-rotating parts (bearing housings) and gives supplementary guidance for shaft vibration measurements where relevant. ISO 10816-7 is intended for use both at the manufacturer’s acceptance test and for in-service condition monitoring and provides criteria to distinguish acceptable vibration levels from those requiring investigation, maintenance, alarm or trip.

Key topics and requirements

• Measurement guidance for vibration on non-rotating parts (bearing housing locations) of rotodynamic pumps.
• Criteria for evaluating overall vibration magnitude and for monitoring changes (trends) in vibration.
• Recommendations for acceptance tests at the manufacturer’s facility and for in-plant acceptance checks.
• Advice on defining operational limits and setting alarm and trip thresholds for long‑term monitoring.
• Instructions on applicability for pump units with integrated electrical motors and for flexibly coupled motor‑pump arrangements.
• General note on assessing shaft vibration in addition to bearing housing vibration where required.

Typical use and users

Used by vibration/condition monitoring engineers, reliability and maintenance teams, pump manufacturers and test laboratories, rotating‑equipment specialists, plant commissioning teams, and consultants involved in acceptance testing and ongoing vibration surveillance of industrial pump installations.

Related standards

ISO 10816-7 is part of the ISO 10816 series on evaluation of machine vibration by measurements on non-rotating parts. Related standards and documents include other parts of ISO 10816 (general and machine‑specific parts), and the newer ISO 20816 family (project work to revise/supersede parts of ISO 10816). National adoptions and identical texts (where applicable) exist in several standards bodies' catalogues.

FAQ

Q: What is this standard?

A: ISO 10816-7:2009 is an international standard that gives guidance for evaluating vibration measured on non-rotating parts (bearing housings) of rotodynamic pumps used in industrial applications.

Q: What does it cover?

A: It covers measurement locations, evaluation criteria for overall vibration and trends, recommendations for manufacturer acceptance tests and in-service monitoring, and guidance for setting operational limits, alarm and trip values. It applies to pumps with nominal power above 1 kW and includes notes on shaft measurements.

Q: Who typically uses it?

A: Maintenance and reliability engineers, vibration analysts, pump manufacturers, test houses, commissioning teams and consultants responsible for pump acceptance testing and condition monitoring.

Q: Is it current or superseded?

A: The document was published in 2009 and remains a published ISO standard; it has been identified for revision and there is work to update parts of the 10816 series under the ISO 20816 project family. Users should check national standards bodies or ISO for the latest status before relying on the standard for compliance-sensitive applications.

Q: Is it part of a series?

A: Yes — it is Part 7 of the ISO 10816 series (evaluation of machine vibration by measurements on non-rotating parts). The ISO 20816 family represents a modernised set of documents that are intended to replace or harmonise parts of the 10816 series over time.
