INDEXING SCHEME ASSOCIATED WITH SUBCLASSES B29B, B29C OR B29D, RELATING TO MOULDING MATERIALS OR TO MATERIALS FOR REINFORCEMENTS, FILLERS OR PREFORMED PARTS, e.g. INSERTS

Introduced: January 1985

Description

B29K is an indexing scheme that classifies materials used in plastic and polymer processing rather than the processing methods themselves. It covers moulding materials (thermoplastics, thermosetting resins, elastomers), reinforcement materials (fibres, fabrics, mats), fillers (mineral, organic), and preformed components such as inserts used in moulding operations. This classification is used as a supplementary index to other B29 subclasses to denote the specific material composition of plastic workpieces and related manufacturing inputs.

Of 371 combined children, 0 exist in both systems.

227 codes are CPC-only extensions, 144 exist only in IPC.

Note: 227 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1985.
