Full title and description

Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating parts — Part 5: Machine sets in hydraulic power generating and pumping plants (ISO 10816-5:2000). This International Standard gives procedures for measurement and evaluation of vibration on non-rotating parts (for example bearing housings) of machine sets used in hydraulic power generating and pumping plants.

Abstract

ISO 10816-5:2000 specifies measurement locations, measurement quantities (displacement/velocity), instrumentation and frequency ranges, operational conditions and evaluation criteria for assessing vibration magnitudes and monitoring changes on machine sets in hydraulic power and pumping plants. It provides guidance for both acceptance/repair decisions (preventing damage) and monitoring for diagnostic/prognostic purposes.

Scope

This part of ISO 10816 applies to machine sets in hydraulic power generating and pumping plants and covers vibration evaluation by measurements on non-rotating parts (typically bearing housings and adjacent structures). It is intended to provide criteria and procedures for: (a) preventing damage by assessing absolute vibration magnitudes and (b) monitoring changes in vibrational behaviour for diagnosis and prognosis. It does not replace application-specific investigation where external transmitted vibration or unusual installation conditions dominate.

Key topics and requirements

• Measurement quantities: preferred use of vibration velocity for medium/high-speed machines and displacement for low-speed machines; guidance on broad-band and narrow-band measurement approaches.
• Measurement locations and directions: representative locations on bearing housings/pedestals; typically two orthogonal radial directions and axial where appropriate; selection to avoid local resonances.
• Measurement equipment and frequency ranges: requirements for flat response across specified frequency bands (e.g., velocity measurements commonly quoted from 2 Hz to 1 000 Hz) and appropriate transducer mounting.
• Operational conditions: measurements to be made under steady-state conditions representative of normal operation; guidance on reduced-speed or no-load measurements where relevant.
• Evaluation criteria: defined acceptance/alert/alarm bands and procedures for monitoring changes (purpose A: prevent damage; purpose B: monitor for diagnosis/prognosis).
• Interpretation guidance: cautions about vibration transmitted from foundations or external sources and the need for special investigation when external excitation is significant.

Technical measurement and evaluation details are described in the standard text and related guidance documents.

Typical use and users

Primary users are vibration analysts, rotating‑machine maintenance engineers, condition‑monitoring specialists, power plant mechanical engineers and consultants involved with hydroelectric turbines, pump sets and pump‑storage installations. The standard is used for acceptance testing, periodic condition assessments, alarm-setting and establishing thresholds for maintenance intervention.

Related standards

ISO 10816-5:2000 is part of the ISO 10816 family of standards for evaluation of machine vibration by measurements on non-rotating parts. It has been superseded by ISO 20816-5:2018 (covering similar machine sets in hydraulic power generating and pump‑storage plants). Other related parts and documents in the vibration measurement and evaluation series (ISO/TC 108/SC 2) include various parts addressing different machine types and measurement methods.

FAQ

Q: What is this standard?

A: ISO 10816-5:2000 is an International Standard that specified procedures and evaluation criteria for measuring and assessing vibration on non-rotating parts of machine sets used in hydraulic power generating and pumping plants.

Q: What does it cover?

A: It covers measurement locations, measurement quantities (displacement and velocity), instrument requirements and frequency ranges, operational conditions for testing, and evaluation criteria (acceptance/alert/alarm bands) for hydraulic power and pumping machine sets.

Q: Who typically uses it?

A: Maintenance and reliability engineers, vibration analysts, plant operators and consultants working with hydroelectric turbines, large pumps and pump‑storage installations use the standard for acceptance testing, monitoring and troubleshooting.

Q: Is it current or superseded?

A: ISO 10816-5:2000 has been withdrawn and superseded by ISO 20816-5:2018, which provides the updated measurement and evaluation guidance for the same class of machines. Users should refer to ISO 20816-5:2018 for the current requirements.

Q: Is it part of a series?

A: Yes. It is (was) part of the ISO 10816 family (measurement and evaluation of machine vibration by measurements on non-rotating parts) and the subject matter is now continued in the ISO 20816 series addressing measurement and evaluation of machine vibration.
