DEFINITION

Classification: 149/40

(under subclass 37) Compositions which contains at least two oxygen yielding compounds.

(1) Note. For the purpose of this and related subclasses a mixture of like compounds which differ in say, degree of oxidation, is not considered as being different oxygen supplying compounds under the definition of this subclass (e.g., a mixture of Fe2O3 and Fe3O4 is regarded as one compound).
