Note(s) In this sub-class, compositions are classified according to the mutual proportions by weight of only the macromolecular constituents. [2] Compositions are classified according to the macromolecular constituent or constituents present in the highest proportion; if all these constituents are present in equal proportions the composition is classified according to each of these constituents. [2] In this sub-class it is desirable to add, in conformity with paragraph 61 of the Guide, after the double oblique stroke the symbols relating to complementary information concerning individual constituents of a technical subject unit which is already classified as such. This complementary information concerns the indication of the additional macromolecular constituents of the composition. [2] The term "rubber" includes: natural or conjugated diene rubbers; rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for compositions of such macromolecular compounds).
