\nT/CICEIA /CAMS116-2025 Rapid Evaluation Method for Metal Content in Nitrogen Oxide Reducing Agents for Diesel Engines
T/CICEIA /CAMS116-2025 Diesel engine nitrogen oxide reduction agent metal content rapid evaluation method
Basic Information
Scope
Scope: This document defines the terms and definitions of the rapid evaluation method for the metal content in nitrogen oxide reducers for diesel engines, describes the test method, and specifies the evaluation method. This document is applicable to the rapid evaluation of whether the metal content (calcium, iron, copper, zinc, chromium, nickel, aluminum, magnesium, sodium, and potassium) in urea aqueous solution (AUS 32), a nitrogen oxide reducer for diesel engines, is acceptable, but it is not applicable to the detection of the specific values of metal ion content.
