Preventive Maintenance

Preventive Maintenance

One of the requirements of the ISO 9001:2000 standard is that you have a preventive maintenance process in place. As an auditor, I will share with you some typical audit findings related to the maintenance process. I will also provide you with a sample section from a quality manual and a maintenance procedure.

Typical audit findings are:
  • Maintenance schedule was not followed.
  • Maintenance was not performed when scheduled.
  • All equipment was not in the maintenance schedule.
  • Equipment is only serviced during breakdown.

Summary

As always, the existence of your company is dependent on your ability to deliver quality products and services that get to your customer on time. How well you plan and control your processes are vital if you are to provide quality. A well-planned and well-executed maintenance process will allow you to meet production and delivery schedules by preventing unscheduled machine down time.
