Condition-based maintenance and repairs (CBM)

Condition-based maintenance and repairs

Condition-based Maintenance (CBM) is a preventive method in maintaining equipment and devices. In this method, the conditions and symptoms that appear in the equipment and devices are used to determine the time for preventive maintenance and immediate repair. In this article, we will discuss the benefits, maintenance and repair implementation steps based on the conditions and important points in its implementation.

Condition-based maintenance and repairs are a set of activities that are carried out with the aim of maintaining efficiency and improving the efficiency and useful life of equipment, buildings and improving specific conditions. In this method, maintenance and repairs are done based on the environmental conditions and instead of implementing standard programs, they are done to have suitable conditions.

  • Condition-based maintenance services:

  1. Reduced maintenance costs due to timely and accurate preventive repairs
  2. Increasing the useful life of equipment and devices due to timely repairs and before serious breakdowns
  3. Reducing production stoppages due to equipment failure
  4. Improved productivity due to no need to stop work for major repairs
  5. Improving the quality of products due to reducing the number of failures

To perform Condition-based Maintenance, the environmental conditions and the use of the contractor must be checked first. For example, if equipment and supplies are in a dry, low-use environment, they require different maintenance and repairs than in an environment with increased chemicals. Similarly, the type of use of the equipment should also be considered. For example, the maintenance and repair needs of a medical office ventilation system are different from a factory ventilation system.

By determining the environmental and user conditions, the required maintenance and repairs program is prepared. In this program, activities such as  replacement of parts , course repairs , regular inspections and emergency repairs are considered. For example, in a dry environment, ventilation filters may need to be replaced, while in a humid environment, they may need to be repaired.

Condition-based maintenance and repairs
  • Implementation steps:

1. Identify the conditional parameters: In this step, you need to identify the conditional parameters. These parameters include temperature, pressure, vibration, etc.

2. Selection of Conditional Sensors: In this step, you should select sensors that are capable of measuring conditional parameters.

3. Collecting Conditional Data: In this step, you need to store the conditional data collected by the sensors.

4. Condition data analysis: In this step, you need to analyze the condition data so that you can arrive at the right time for preventive maintenance and spot repairs.

5. Determining the time of repairs: In this step, you should determine the time of preventive repairs and immediate repairs based on the analysis of condition data.

In condition-based maintenance, we also seek to improve performance and reduce costs. By carrying out basic and effective repairs, the useful life of equipment and facilities will be increased and the need for frequent repairs will be reduced. Also, by making repairs at the right time and using original and authentic parts, you can reduce the costs of troubleshooting and emergency repairs.

  • Important points in performing condition-based maintenance and repairs:

  • Using quality sensors to measure condition parameters

  • Collection and storage of condition data periodically and on time

  • Periodic and timely analysis of conditional data

  • Determining the time of preventive repairs and immediate repairs accurately and on time


In general, condition-based maintenance is a preventive method to maintain and improve the performance and useful life of equipment, buildings and facilities. According to the environmental and user conditions, a suitable maintenance and repair program is prepared and by performing basic and effective repairs, the costs related to emergency repairs and troubleshooting are reduced. By following the important points in implementing this method, you can use it in the best way and improve the performance of your equipment and devices.
