Understanding ISO 13485 Audit Processes

What is an ISO 13485 Audit?

ISO 13485 specifies requirements for a QMS where an organization needs to demonstrate its ability to provide medical devices and related services that consistently meet customer and applicable regulatory requirements. The primary objective of ISO 13485 certification is to facilitate harmonized QMS requirements in the medical device sector on a global scale.

Types of Audits

  1. Internal Audits: Conducted by the organization to ensure that its QMS is effectively implemented and maintained.
  2. External Audits: Conducted by third-party certification bodies to verify compliance with ISO 13485.
  3. Supplier Audits: Assessing suppliers' compliance to ensure their processes align with the organization's QMS requirements.

Preparing for the ISO 13485 Audit
