A Guide to Auditing Material Test Reports
When it comes to maintaining AS9100 certification, one critical aspect is the auditing of receiving processes, particularly the comparison of Material Test Reports (MTRs) to actual specifications. This step is crucial to ensure that materials meet the required standards and specifications, not just the Purchase Order (PO) requirements. The following is a guide to auditing material test reports.
Why is this Important?
The AS9100 standard mandates that organizations must have a process in place to evaluate the data in test reports to confirm that the product meets the necessary requirements. This means that auditors must have access to the actual specifications and must compare the values required for material composition against what the test report states[1].
Common Practices and Auditor Expectations
Auditors' expectations can vary significantly. Some auditors may allow for this comparison to be done on a sample basis, such as 1 out of every 10 or 20 reports[2]. Others may permit organizations to delegate this responsibility to their supply chain, requiring distributors or suppliers to perform the checks, with the organization only verifying periodically (e.g., monthly or quarterly)[3]. Additionally, some auditors may accept alternative verification methods, such as sending samples to a test lab or using an XRF gun to test each batch[4].
Understanding Section 8.4.2 Requirements
Section 8.4.2 of the AS9100 standard outlines specific requirements for using external provider test reports[5]:
Evaluation of Test Reports: When external provider test reports are used to verify products, the organization must implement a process to evaluate the data in these reports to confirm that the product meets requirements[6].
Validation of Test Reports: If raw material is identified as a significant operational risk (e.g., critical items), the organization must implement a process to validate the accuracy of these test reports[7].
Practical Implementation
In practice, this means that organizations should:
Have Access to Specifications: Ensure that auditors have access to the actual specifications and can compare them against the MTRs[8].
Implement a Robust Process: Develop and implement a process for evaluating and validating test reports, especially for critical materials[9].
Periodic Verification: Depending on the auditor's requirements, perform periodic checks or delegate the responsibility to suppliers, ensuring that the process is documented and followed consistently.
Conclusion
While auditors may have different approaches, it is essential for organizations to have a clear and documented process for evaluating and validating Material Test Reports. By doing so, they can ensure compliance with AS9100 and maintain the integrity of their materials and products.
