Coating Field Notes: Separate the Observation from the Proposed Explanation

A field note should record what was observed before stating why the observer thinks it happened. Keeping those layers separate helps later reviewers consider alternative explanations without losing the original evidence.

Updated · NANOLAB Knowledge

The key distinction

Describe the location, condition, timing and inspection context in concrete terms. Then label the proposed cause as a hypothesis unless it has been established through an appropriate investigation. This makes support records more useful than a confident diagnosis that omits the visible facts behind it.

Practical checks

  1. Record the direct observation and relevant photographs.
  2. List recent exposures or process changes without assuming causation.
  3. State the hypothesis and the next check that could support or challenge it.

Example

Illustrative example: a note says coating failed after the surface shows reduced water beading. A more useful record describes the water behaviour, cleaning history and test conditions, then identifies failure as one possibility to investigate. The revised note preserves evidence instead of embedding an unverified conclusion.

Scope and limits

Do not treat cautious wording as a reason to ignore a genuine problem. The purpose is a better investigation, not a favourable narrative. This guide does not diagnose coating condition from a single observation or replace the product supplier's technical assessment.
