ISO 9001 Internal audit clauses

That will depend on the scope of the audit. If your organization performs an annual internal audit, all clauses have to be included. For example, if you are going to audit the production process, perhaps you must include the following ISO 9001:2015 clauses:

• 7.1.3 – about equipment maintenance
• 7.1.4 – about production environment
• 7.1.5 – about monitoring and measuring resources
• 7.2 – about people’s competence
• 7.3 – about people knowing the quality policy
• 7.5 – about documents and records control
• 8.5 – about specifications, process control plans, work instructions, traceability, preservation,
• 8.6 – quality control
• 8.7 – nonconforming product treatment
