Traceability ensures that calibration results can be linked to national or international standards through an unbroken chain of comparisons. It is essential for:

1. Compliance: Meeting ISO 17025 and other regulatory requirements.

2. Quality Assurance: Ensuring consistent and reliable measurements.

3. Audits: Providing documented evidence of calibration processes.

Key takeaways:

• Traceability is critical for compliance and quality assurance.

• Use certified reference materials and equipment for reliable results.
