    AI Overview
    DIN 70070 is a German standard for AdBlue (AUS 32), a 32.5% high-purity urea and 67.5% deionized water solution used in diesel SCR systems to reduce NOx emissions. It ensures urea content (31.8–33.2%), density, and purity to prevent catalytic converter damage. It is non-hazardous, colorless, and acts as a urea-based NOx reduction agent. 
    Key Aspects of DIN 70070 AdBlue (AUS 32) 
    • Composition: 32.5% industrial urea / 67.5% deionized water.
    • Purpose: Essential in Selective Catalytic Reduction (SCR) technology for diesel engines (trucks, cars, machinery) to meet EURO 4/5/6 standards by converting nitrogen oxides into nitrogen and water.
    • Standards & Specifications (DIN 70070 / ISO 22241):
      • Urea Content:
        32.5
        %
        ±0.7
        %
        .
      • Density (
        𝟐𝟎∘
        𝑪
        ):
        1.087
        −1.093
        g/cm3
        .
      • Refractive Index (
        𝟐𝟎∘
        𝑪
        ):
        1.3817
        −1.3840
        .
      • Appearance: Transparent, colorless liquid with a slight ammonia odor.
    • Storage & Handling: Optimal storage temperature is between
      −5∘
      𝐶
       and
      25∘
      𝐶
      . Freezing occurs at roughly
      −11∘
      𝐶
      , and prolonged high temperatures cause decomposition.
    • Other Names: In addition to AdBlue (Europe/China), it is referred to as DEF (Diesel Exhaust Fluid) in the Americas, ARLA32 in Brazil, and AUS 32 (Aqueous Urea Solution 32.5%) generically. 
    Production and Testing 
    • It is produced by mixing high-purity urea with demineralized water.
    • The solution should be tested for purity, particularly alkalinity, biuret content, and insolubles, to ensure it adheres to the DIN 70070 standard, preventing damage to the SCR catalytic converter.
