Oxygen balance - Wikipedia
Oxygen balance (OB, or OB%) is an expression that is used to indie the degree to which an explosive can be oxidized.If an explosive molecule contains just enough oxygen to form carbon dioxide from carbon, water from hydrogen atoms, all of its sulfur dioxide from sulfur, and all metal oxides from metals with no excess, the molecule is said to have a zero oxygen balance.
