Understanding Clause 7.1.5.2 – Measurement Traceability:ISO 9001:2015 requires organizations to ensure that measuring equipment (e.g., spectrometers) is calibrated and traceable to recognized standards. The failure to maintain calibration within valid dates directly violates this clause and raises concerns about the reliability of the measurement results.

Root Cause of the Nonconformity:The organization failed to plan for the possibility that the calibration service provider (X-TECH) might become unavailable, leading to expired calibration. This indicates inadequate risk-based thinking, which is required under Clause 6.1 of ISO 9001:2015.

Option Analysis:

A. Select one sample for external lab analysis to use as an internal standard:Incorrect. While using an internal standard could provide short-term verification of results, this action does not address the root cause (failure to consider risks associated with external providers).

B. Look for a local company to provide this service:Incorrect. While finding a new local service provider resolves the immediate calibration issue, it does not address the risk of future provider unavailability.

C. Double-check one out of ten samples externally:Incorrect. This corrective action ensures some quality assurance for batch release but does not resolve the nonconformance related to expired calibration.

D. Add this issue to the external issue register, assess its associated risk, and plan action to address that risk:Correct. This approach directly addresses the root cause (failure to anticipate the calibration provider leaving) and ensures proper risk management. ISO 9001:2015 emphasizes risk-based thinking under Clause 6.1, requiring organizations to identify risks and opportunities and implement plans to mitigate them.

Why D is the Best Option:

By adding the issue to the external issue register, the organization ensures it is monitored and tracked.

Assessing the risk ensures proactive measures are in place for similar issues in the future.

Planning actions to address the risk ensures a sustainable solution is implemented, such as identifying multiple service providers or ensuring backup plans for calibration services.
