What is the National 5 Standard for 176 Diesel?
1 Answers
Diesel National 5 Standard is evaluated based on anti-knock quality, volatility, fluidity, corrosiveness, and stability. The detailed criteria are as follows: 1. Anti-knock quality: The cetane number is the indicator for evaluating the anti-knock quality (ignition performance) of diesel. 2. Volatility: The indicators for evaluating diesel volatility are distillation range and flash point. 3. Fluidity: The indicators for evaluating diesel fluidity are viscosity, freezing point, and cold filter plugging point. 4. Corrosiveness: The indicators for evaluating diesel corrosiveness are sulfur compounds and sulfur content. 5. Stability: The indicators for evaluating diesel stability are total insolubles and 10% carbon residue of distillation residue.
