ASTM D4065

ASTM D4065 is a standardized test method used to determine the sulfur content in liquid petroleum products such as fuels and oils. It involves chemically analyzing a sample to measure how much sulfur is present, which is important because sulfur can affect fuel performance and environmental emissions. Accurate sulfur measurement ensures compliance with regulations and helps consumers and manufacturers manage fuel quality. This method provides reliable, standardized results, making it a key tool in quality control and regulatory compliance within the petroleum industry.
