Which Clause in ISO 9001 Covers Equipment Maintenance?

The Short Answer: Clause 7.1.3

If you are looking for the specific clause in ISO 9001:2015 that covers equipment maintenance, the answer is Clause 7.1.3 Infrastructure. This clause requires organisations to determine, provide, and maintain the infrastructure necessary to operate their processes and achieve conformity of products and services.

That said, equipment maintenance in ISO 9001 is not confined to a single clause. Depending on how your equipment is used and what it affects, you may also find relevant requirements in Clause 7.1.5 (Monitoring and Measuring Resources), Clause 8.5.1 (Control of Production and Service Provision), and Clause 10.2 (Nonconformity and Corrective Action). We will cover all of these in detail below.

For a broader understanding of how the standard is structured, it helps to first read our beginner's guide to ISO 9001:2015 before diving into individual clauses.

What Does Clause 7.1.3 Infrastructure Actually Require?

Clause 7.1.3 is part of Section 7, which covers the support requirements of your quality management system. The clause reads simply but carries significant weight. Organisations must determine, provide, and maintain the infrastructure needed for the operation of its processes and to achieve conformity of products and services.

The standard then gives examples of what infrastructure can include:

• Buildings and associated utilities
• Equipment, including hardware and software
• Transportation resources
• Information and communication technology

The word maintain is doing a lot of work in that sentence. It is not enough to simply have the equipment. You need to demonstrate that you are actively keeping it in a condition that supports consistent, conforming output. That means planned maintenance schedules, records of servicing, and evidence that breakdowns or deterioration are being managed rather than ignored.

What Does “Maintain” Mean in Practice?

ISO 9001 does not prescribe how you maintain your equipment. It does not tell you to use a particular maintenance software, follow a specific schedule, or hire a dedicated maintenance team. What it does require is that your approach is systematic and documented well enough to demonstrate control.

In practical terms, most businesses satisfy Clause 7.1.3 through some combination of the following:

• A preventive maintenance schedule covering critical equipment
• Service records or logbooks showing when maintenance was performed and by whom
• Calibration records where applicable (more on this under Clause 7.1.5)
• A process for reporting and responding to equipment faults or breakdowns
• Evidence that maintenance tasks are assigned to competent personnel or qualified contractors

A small food manufacturer in regional Victoria, for example, might satisfy this clause by keeping a simple spreadsheet showing monthly cleaning and lubrication of their packaging line, quarterly servicing by an external technician, and a fault log where operators record any issues during production. That is entirely sufficient. You do not need a sophisticated computerised maintenance management system to comply, though larger organisations often benefit from one.

Clause 7.1.5: Monitoring and Measuring Equipment

This is where many businesses get confused. Clause 7.1.5 deals specifically with monitoring and measuring resources, which includes equipment used to verify that products or services meet requirements. Think of test instruments, gauges, scales, thermometers, pressure gauges, and similar devices.

The requirement here goes beyond general maintenance. Clause 7.1.5 requires that measuring equipment is:

• Calibrated or verified at specified intervals, or prior to use, against measurement standards traceable to national or international standards
• Identified so that calibration status can be determined
• Safeguarded from adjustments, damage, or deterioration that would invalidate the calibration status
• Stored and handled appropriately

This is a separate and more specific obligation than the general infrastructure maintenance required under 7.1.3. If your business uses a torque wrench to assemble components to a specified torque, that wrench needs to be calibrated. If you use a temperature probe to verify that a food product reaches a safe internal temperature, that probe needs calibration records traceable to a national standard.

The distinction matters because auditors treat these two clauses differently. A general maintenance schedule for your production line addresses 7.1.3. Calibration certificates for your measuring instruments address 7.1.5. You need evidence for both, and confusing them is a common source of nonconformities during certification audits.

What Happens When Measuring Equipment Is Found to Be Out of Calibration?

This is an important question and ISO 9001 addresses it directly. When measuring equipment is found to be invalid, you must evaluate and record the validity of previous measurement results. You then need to take appropriate action on the equipment and on any product or service that may have been affected.

In plain terms: if your thermometer was reading three degrees too low for the past six weeks, you need to assess what product was made during that period, whether it still meets requirements, and what you will do about it. This links directly to Clause 10.2 on nonconformity and corrective action, which we will come to shortly.

Clause 8.5.1: Control of Production and Service Provision

Clause 8.5.1 covers the controlled conditions under which production and service delivery must occur. Equipment maintenance appears here in a different form. The clause requires that organisations implement production and service provision under controlled conditions, which includes:

• The use of suitable infrastructure and environment for the operation of processes
• The availability and use of suitable monitoring and measuring resources
• Implementation of monitoring and measurement activities at appropriate stages

The connection to equipment maintenance here is about operational readiness. If a piece of equipment is not maintained and fails mid-production, you have lost control of your process. Auditors looking at Clause 8.5.1 will want to see that your production conditions are consistently controlled, and that includes the reliability and fitness for purpose of the equipment being used.

Think of a commercial printing business. If their colour calibration equipment is not regularly maintained and calibrated, they cannot reliably produce colour-accurate output. Clause 8.5.1 would be relevant here alongside 7.1.3 and 7.1.5, because the lack of maintenance directly affects their ability to control the production process.

Clause 10.2: Nonconformity and Corrective Action

Equipment failures do not just affect production. They generate nonconformities, and those nonconformities need to be managed under Clause 10.2. When a piece of equipment breaks down and causes defective output, or when calibration records reveal that a measuring device has been out of tolerance, you are dealing with a nonconformity.

Clause 10.2 requires you to react to the nonconformity, evaluate the need for action to eliminate the cause, and implement any necessary corrective actions. In the context of equipment maintenance, this might mean:

1. Identifying the failed equipment and quarantining any affected product
2. Investigating why the failure occurred (was the maintenance schedule inadequate? Was a service skipped?)
3. Updating the maintenance schedule or procedure to prevent recurrence
4. Verifying the effectiveness of the corrective action over time

This is where a reactive maintenance culture becomes a problem in ISO 9001 audits. If your records show repeated breakdowns of the same equipment with no evidence that you investigated root causes or improved your maintenance approach, an auditor will raise a nonconformity against Clause 10.2 as well as 7.1.3.

What Does an Auditor Actually Look for During an Equipment Maintenance Review?

Having been through certification audits on both sides of the table, here is what auditors typically examine when reviewing equipment maintenance compliance in ISO 9001:

1. A Register of Critical Equipment

Auditors expect to see a list or register of equipment that is relevant to product or service quality. Not every piece of equipment needs to be on the list. A desk fan in the office does not need a maintenance record. But the injection moulding machine, the calibrated pressure gauge, and the clean room HVAC system absolutely do. The register should include the equipment name, identification number, location, maintenance frequency, and calibration requirements where applicable.

2. Maintenance Records That Match the Schedule

A maintenance schedule on paper means nothing if the records do not show it was followed. Auditors will compare your planned maintenance schedule against your actual service records. Gaps are a red flag. If your schedule says quarterly servicing but your records show it happened once in eighteen months, expect a finding.

3. Calibration Certificates With Traceability

For measuring equipment, auditors will want to see calibration certificates from accredited laboratories. The certificates need to show traceability to national measurement standards. In Australia, this typically means the National Measurement Institute (NMI) or a laboratory accredited by NATA (National Association of Testing Authorities). A calibration sticker on a gauge is not sufficient on its own. You need the actual certificate.

4. Evidence of Competence for Maintenance Personnel

Under Clause 7.2 (Competence), anyone performing maintenance tasks needs to be competent to do so. That might mean internal training records, trade qualifications, or evidence that an external contractor is appropriately qualified. An auditor who finds that your maintenance is performed by untrained staff with no documented competence will raise findings against both 7.1.3 and 7.2.

5. A Process for Handling Equipment Failures

What happens when a machine breaks down unexpectedly? Is there a documented process? Who decides whether product made on that machine before the failure is still acceptable? Auditors want to see that you have thought through this scenario and have a clear process for managing it.

Common Mistakes Businesses Make With Equipment Maintenance in ISO 9001

After reviewing dozens of quality management systems, these are the patterns that come up repeatedly:

• Treating calibration and general maintenance as the same thing. They are not. Calibration is a specific, traceable activity for measuring equipment. General maintenance is broader. Mixing them up leads to gaps in both areas.
• Maintaining equipment but not documenting it. ISO 9001 requires documented information as evidence of conformance. Verbal confirmation that “yes, we service the machines regularly” is not acceptable. Write it down.
• Only maintaining equipment when it breaks. Reactive maintenance is not a controlled approach. ISO 9001 expects you to have a preventive maintenance plan, not just a repair log.
• Forgetting about software. Clause 7.1.3 explicitly includes software as infrastructure. If your business relies on a specific software system to deliver your product or service, you need to demonstrate that it is maintained, updated, and backed up appropriately.
• Not linking equipment failures to corrective action. Every significant equipment failure should generate a corrective action record. Many businesses fix the problem but never formally record the root cause analysis or the actions taken to prevent recurrence.

If you want to understand how your overall quality management system should be structured to avoid these gaps, our guide to Clause 4.4 and the QMS process approach provides useful context.

How to Build a Simple Equipment Maintenance System That Satisfies ISO 9001

You do not need to overcomplicate this. Here is a practical approach that works for most small to medium businesses:

1. Create an equipment register. List every piece of equipment that affects product or service quality. Include ID numbers, location, and whether calibration is required.
2. Set maintenance frequencies. For each item, document how often it needs to be serviced, cleaned, lubricated, or otherwise maintained. Base this on manufacturer recommendations and your own operational experience.
3. Assign responsibility. Who is responsible for ensuring each maintenance task is completed? Make it explicit.
4. Record everything. Whether it is a spreadsheet, a maintenance logbook, or a dedicated software system, every maintenance activity needs a record. Date, task performed, who performed it, outcome.
5. Set up calibration cycles. For measuring equipment, establish calibration intervals and ensure certificates are obtained from accredited sources. Keep the certificates on file.
6. Build in a review process. At least annually, review your maintenance records as part of your management review. Are there recurring failures? Are schedules being met? What improvements are needed?

This does not need to be a complex system. A well-maintained spreadsheet with consistent records will satisfy an auditor far better than an elaborate software system with incomplete data.

Does ISO 9001 Require a Documented Maintenance Procedure?

This is a question that comes up often. ISO 9001:2015 does not explicitly require a documented maintenance procedure. The standard requires documented information only where specified, and Clause 7.1.3 does not mandate a formal procedure document.

However, it does require that you retain documented information as evidence of conformance. In practice, this means you need maintenance records even if you do not need a formal procedure. Most auditors would also expect to see some form of documented schedule or plan, because without one it is difficult to demonstrate that your maintenance approach is systematic rather than ad hoc.

The safest approach for most businesses is to have a brief maintenance procedure or plan that outlines what equipment is covered, how often it is maintained, who is responsible, and how records are kept. This document does not need to be lengthy. Two or three pages covering the key points is entirely adequate for most businesses.
