ASTM D-13 (Oil and Grease)

ASTM D-13 refers to a set of standards established by ASTM International for testing oil and grease in various materials, primarily water. This includes methods for identifying and measuring the presence of oil and grease, which can indicate pollution levels in waterways. The tests help assess water quality, ensuring compliance with environmental regulations. By analyzing samples, organizations can determine the impacts of industrial discharge, runoff, or spills, enabling them to take appropriate measures to protect ecosystems and public health.
