• Framework for acceptance criteria and actionable steps for setting alarms and trip points based on vibration magnitude and variation
• Evaluation that only considers vibration generated by the machine itself

Implementation and Compliance

Targeted at OEMs, plant operators, maintenance engineers, and compliance managers, ISO 20816-1:2026 provides a flexible yet robust backbone for building condition monitoring and preventive maintenance programs.

• Continuous and periodic monitoring methods
• Broad-band vibration evaluation near bearings, pedestals, and critical shaft locations
• Practical advice for deciding between shaft and housing vibration measurement, depending on machine design and fault detection objectives

Key Requirements and Specifications

• Measurement equipment must meet flat response over frequency ranges suitable for the rotating speed (typically 10 Hz–1,000 Hz), supported by relevant ISO cross-references (ISO 20816-1, ISO 10817-1)
• Classification of machines by power, shaft height, and support structure flexibility (rigid vs flexible)
• Precise directions on when and how to apply Criterion I (vibration magnitude) and Criterion II (vibration change) for operational safety and acceptance testing
• Procedures for managing and discounting background vibration
• Annexes with formulas, evaluation zones, and supplementary assessment guidelines for specific machine types

Implementation and Compliance

Relevant for industries operating critical rotating capital assets—energy, manufacturing, chemicals, and process industries—ISO 20816-3:2026 is indispensable for machine designers, asset managers, and quality assurance professionals.

Notable 2026 Revisions
