with oxides, hydroxides or mixed oxides; with salts derived from anions with an amphoteric element-oxygen bond

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Treating fibres, threads, yarns, fabrics or fibrous goods made from such materials, with inorganic substances or complexes thereof; Such treatment combined with mechanical treatment, e.g. mercerising > with oxygen, ozone, ozonides, oxides, hydroxides or percompounds; Salts derived from anions with an amphoteric element-oxygen bond > with oxides, hydroxides or mixed oxides; with salts derived from anions with an amphoteric element-oxygen bond

CPC:

Treating fibres, threads, yarns, fabrics or fibrous goods made from such materials, with inorganic substances or complexes thereof; Such treatment combined with mechanical treatment, e.g. mercerising (D06M10/00 takes precedence) > with oxygen, ozone, ozonides, oxides, hydroxides or percompounds; Salts derived from anions with an amphoteric element-oxygen bond (with water or heavy water D06M11/05; with oxides or oxyacids of halogens D06M11/30) > with oxides, hydroxides or mixed oxides; with salts derived from anions with an amphoteric element-oxygen bond

IPC and CPC are identically structured here. All 7 subcodes exist in both systems.

IPC defines codes here since 1990.
