Diesel exhaust fluid definition

Diesel exhaust fluid or “DEF” means a liquid reducing agent used in conjunction with selective catalytic reduction to reduce NOx emissions. DEF is generally understood to be an aqueous solution of urea conforming to the specification of ISO 22241.
Diesel exhaust fluid means an aqueous urea solution
Diesel exhaust fluid means a preparation of aqueous urea [(NH2)2CO], containing 32.5 per cent by mass of technically-pure urea in high-purity water.
