AdBlue / diesel exhaust fluid
Identity, urea concentration and impurity-related parameters aligned with the published AdBlue capability.| Test / parameter | Published method | Technical purpose | Interpretation context | Capability |
|---|---|---|---|---|
| Urea Content | ISO 22241-2 Annex C | Measures or evaluates urea content under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Refractive Index | ISO 22241-2 Annex C | Measures or evaluates refractive index under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Alkalinity as NH₃ | ISO 22241-2 Annex D | Reports selected wear, contaminant, additive or composition-related elements. | Higher or lower values require comparison with formulation, metallurgy, process inputs and trend history; one result alone does not establish the source. | Inhouse |
| Biuret | ISO 22241-2 Annex E | Measures or evaluates biuret under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Aldehydes | ISO 22241-2 Annex F | Measures or evaluates aldehydes under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Phosphate | ISO 22241-2 Annex H | Measures or evaluates phosphate under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Identity | ISO 22241-2 Annex J | Measures or evaluates identity under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
