For which of the following purposes would one use QA Form 28?

QA Form 28 is specifically designed for recording a Shop Test, which involves documenting the results of tests performed on products or components during the manufacturing process. This form ensures that test procedures and results are systematically captured and can be reviewed or audited later.

Using QA Form 28 for this purpose allows for consistency in data reporting and aids in quality control by keeping detailed records of the conditions and outcomes of each test. These records are critical in confirming that products meet specified requirements and standards before they are finalized or delivered.

While other aspects like torque application, thickness measurement, and documenting drop tests are important quality assurance activities, they would typically require different forms or reports tailored to those specific tasks. QA Form 28 is not intended for capturing data outside of the scope of shop test results, highlighting its specialized utility in the QA documentation process.
