Mixed Mirror and Brushed Stainless Assemblies: Use Separate Appearance References

Use distinct appearance standards for mirror and brushed stainless parts so one acceptance image does not misjudge the other finish.

An assembly containing mirror and brushed stainless steel needs more than one appearance reference. The finishes respond differently to viewing direction and reflected surroundings, so a single photograph or gloss target may not describe both adequately.

Identify finish boundaries

Mark each finish on the drawing and confirm the supplied material. Include welds, returns and decorative transitions that may have a different local finish. Keep a physical reference sample for each accepted surface where practical.

Set suitable observations

Finish Useful inspection control
Mirror Consistent reflected scene and viewing position
Brushed Consistent grain direction, illumination and angle
Transition Defined boundary and local workmanship reference

If instruments are used, confirm that their method and geometry suit the particular finish. A number collected outside a method’s useful conditions should not overrule a relevant visual observation.

Trial the complete combination

Apply the proposed treatment to representative samples of both finishes, retaining untreated references. Use the intended preparation and care method. Evaluate streaking, colour or texture changes and cleaning results separately rather than averaging unlike appearance scores.

Make handover criteria readable

The acceptance sheet should identify which reference belongs to each zone. For example, a mirror insert can be judged against a controlled reflection while the surrounding brushed panel is checked with its grain vertical. If one finish passes and the other does not, revise the application scope or process for that finish. An overall “pass” should not hide a known local appearance problem.
