What is the ISO standard for vibration severity?

Vibration is a common phenomenon, and it can occur in various machines and structures. Excessive vibration can lead to equipment failure and compromise safety. To ensure reliable performance and minimize risks, the International Organization for Standardization (ISO) has established standards for vibration severity.

The Purpose of ISO Standards

ISO standards provide guidelines and specifications for different aspects of industries and technologies. When it comes to vibration severity, ISO standards help manufacturers, engineers, and maintenance personnel evaluate and compare the vibration levels of different equipment. These standards define the acceptable limits of vibration based on the type and location of the machine or structure.

ISO 10816-1: General Machinery

ISO 10816-1 is a widely used standard for assessing vibration severity in general machinery. It provides guidelines for determining the permissible vibration levels in various types of machines, such as pumps, compressors, and fans. The standard specifies measurement methods, evaluation criteria, and acceptance levels based on the machine's size, operation speed, and mounting configuration.

ISO 7919: Rotating Machinery

ISO 7919 focuses specifically on vibration measurements and analysis for rotating machinery like turbines, generators, and motors. This standard provides detailed procedures for measuring vibration amplitudes and analyzing their impacts on machine performance. It also considers factors like rotational speeds, bearing conditions, and load variations to assess the severity of vibration and potential risks to the equipment.
