ISO 10816

Definition of ISO 10816

ISO 10816 defines an international standard for evaluating machine vibrations through measurements on non-rotating parts, establishing uniform criteria for assessing vibration intensity across various machine types.

Normative Foundations

The ISO 10816 series structures vibration assessment by machine classes:

• Part 1: General guidelines for vibration evaluation.
• Part 2: Classifies steam turbines and generators.
• Part 3: Assesses medium-sized industrial machines.
• Part 4: Sets limits for gas-powered turbomachines.
• Additional Parts: Systematically address specific machine types.

Assessment Criteria

The standard establishes standardized vibration criteria based on effective values:

• Vibration Velocity: Primary parameter in mm/s RMS.
• Evaluation Zones: A (new), B (unlimited), C (restricted), D (damaging).
• Machine Foundations: Rigid or flexible.
• Machine Power: Classified by kW power ranges.
• Machine Speed: Classified by RPM ranges.

Measurement Methods

Standard-compliant measurement requires defined techniques and equipment:

• Measurement Sensors: Positioned at specified points.
• Vibration Transducers: Selected by parameter and frequency range.
• Measurement Chain: Calibrated per standard requirements.
• Measurements: Conducted under defined operating conditions.
• Evaluation: Assessed against specified criteria.

Practical Application

ISO 10816 forms the basis for systematic condition monitoring:

• Baseline Measurements: Establish initial state post-installation.
• Trend Analysis: Identifies gradual condition changes.
• Alarm Limits: Set based on standard thresholds.
• Documentation: Ensures compliance history.
• Maintenance Planning: Driven by objective vibration data.

Consistent application of ISO 10816 standards in industrial maintenance programs enables reliable, uniform machine condition assessment, supporting data-driven maintenance decisions and preventive strategies.
