Coating Test Deviations: Report What Actually Happened

A report should distinguish the planned method from the procedure actually performed. When a deviation occurs, document it and its potential effect before using the result to support a coating claim.

Updated · NANOLAB Knowledge

The key distinction

Deviations can involve sample preparation, exposure, equipment or evaluation. Their importance depends on the question and method, so neither automatic dismissal nor silent omission is appropriate. The laboratory should explain whether the result remains usable and what qualification belongs with the conclusion.

Practical checks

  1. Preserve the original plan and the actual event record.
  2. Obtain the laboratory's assessment of the deviation.
  3. Carry relevant limitations into any purchasing summary or public claim based on the report.

Example

Illustrative example: a specimen experiences an unplanned interruption during exposure. A final table that lists only the intended test duration would hide useful context. The report should state the event and explain how it affects interpretation rather than presenting an idealized version of the work.

Scope and limits

Do not relabel a modified procedure as full compliance with an unchanged method unless that statement is justified. This guide does not decide the validity of a particular test. It establishes a documentation principle: the evidence should describe the work performed, including departures that matter to the conclusion.
