4.9 Control of nonconforming testing and/or calibration work
It is clear that the work of the laboratory is the production of test data. Therefore, nonconforming work is test data that, for some reason, does not meet specifications. Test data may not meet specifications for a variety of reasons, including:
- discovery of defective test equipment
- errors in testing technique
- improper storage of test item
- improper test item preparation; and
- faulty environmental conditions during testing.
When it is discovered that nonconforming work exists, the lab must follow its established procedures to ensure that the deviation is evaluated for significance, and that the customer is notified where necessary. It may also be necessary to halt further work in that area until the problem is eliminated.
