Scope

Scope: This document specifies a method for rapid quantitative detection of automotive diesel using a combination of near-infrared spectroscopy and chemometrics. This document is applicable to the rapid detection of cetane number, cetane index, polycyclic aromatic hydrocarbons (PAHs), pour point, and cold filter plugging point (CFPP) in automotive diesel. It is not recommended for use as an arbitration test. Main technical content: Table 1: Standard analysis items, methods, and repeatability and reproducibility indicators for automotive diesel.
