An iron oxide tinting-strength percentage is meaningful only with its reference standard and preparation method. A value of 100% does not mean pure pigment or universal equivalence across every binder.

The LANXESS BAYFERROX 504 sheet, Specified Color Data names a reference standard, binder and titanium-dioxide reduction. This is an example of method context, not an ENVO specification or a transferable acceptance range.
Retain the reference pigment identity and revision, dispersion procedure, binder, reduction ratio, measurement conditions and calculation. A buyer comparing reports from two suppliers should establish whether the underlying systems are comparable before ranking their percentages.
| Reported field | Misinterpretation to avoid |
|---|---|
| Relative tinting strength | Treating the percentage as pigment purity |
| Colour difference | Comparing values measured against different references |
| Reduced-shade result | Assuming it fully describes the masstone appearance |
Use a common application comparison
Evaluate incumbent and candidate in the intended formulation using a controlled procedure. Record both colour and relevant processing properties. If the formulation team adjusts loading to match the target, retain the actual qualified addition and any remaining shade difference.
For ENVO, provide the current pigment standard, colour system, reduction method and intended use. Ask for actual grade data and a representative sample. This record supports an informed substitution decision without treating one producer’s internal strength scale as a universal measure.
