Colour Checks After Coating: Separate Lighting from Surface Change
A perceived colour difference can depend on the light source and viewing conditions. Repeat the observation before assigning it to the coating.
Coating Test Panels: Keep the Backing Consistent
The support behind a sample can affect how a test is performed or observed. Unrecorded backing changes introduce another variable into comparisons.
Coating Measurement Reports: Preserve Instrument Settings
A number without its method settings may be impossible to reproduce. Saved settings are part of the measurement record.
Coating Contact-Angle Tests: Control the Time After Drop Placement
A contact-angle observation is associated with a measurement time. Comparing an immediate image with a later image introduces a timing difference.
Coating Roughness Measurements: Preserve the Filter and Evaluation Length
Roughness results depend on how the measured profile is processed and evaluated. Method settings belong with the number.
Contact-Angle Reports: Read Left and Right Angles Before Averaging
Unequal left and right drop profiles can signal a geometry or surface issue worth reviewing. An average can conceal that asymmetry.
Coating Test Liquids: Record Purity and Handling
The liquid used in a wetting test is part of the test system. Contaminated water or reused dispensing equipment can undermine a comparison.
Coating Roughness on Directional Finishes: Measure the Specified Traverse
A profile measured along a directional texture can differ from one measured across it. The traverse direction must match the specification.
Coating Inspection Values: Do Not Round Before the Final Decision
Early rounding can change a calculated result or obscure a borderline decision. Preserve the original measurement precision through the analysis.
Coating Laboratory Quotes: Define the Failure Endpoint First
A laboratory cannot design a useful comparison from a request to test durability alone. The endpoint must describe the change that matters.
ATR and Transmission FTIR for Coating Samples: Ask Which Sampling Method Fits
ATR and transmission are different FTIR sampling approaches. Their suitability depends on the specimen and analytical question.
Coating Trials: Separate Positive Controls from Untreated Controls
An untreated control and a reference treatment serve different purposes. The first describes the baseline; the second can help compare the candidate with an established process.
