ISO 14359:1997 PDF

Overview

ISO 14359:1997 - Winter‑sports equipment - Marking of parts made of polymer materials - specifies how separable plastic and elastomer parts used in winter‑sports equipment (for example, ski boots and ski‑bindings) must be marked to enable reliable identification and facilitate recycling. The standard sets minimum marking requirements for thermoplastics, thermosets and elastomers, and explains formats, symbol use and placement. It does not apply to compound materials with duroplastic components (e.g., skis).

Key topics and technical requirements

• Scope & intent: Minimum requirements for identifying polymer parts so materials can be completely separated for recycling. Marking is mandatory unless technical or geometrical reasons make marking impossible.
• Referenced standards: Marking symbols follow ISO 1043‑1 and ISO 1043‑2 (plastics symbols) and ISO 1629 (rubber/elastomers).
• Marking structure (thermoplastics/thermosets):
  • Basic polymer symbol (e.g., PA6, PC, POM)
  • Material variant (e.g., PA66)
  • Filler/reinforcement symbol and percentage by mass (e.g., GF30 for 30% glass fibre)
  • Example: >PA66-GF30<
• Blends and copolymers:
  • Blends separated by a plus sign (e.g., >PC+PBT<)
  • Copolymers separated by a slash (e.g., >PA6/12<)
• Compound parts: Individual part areas are labelled with their material (e.g., Housing >POM<, Window >PC<).
• Filler mixtures: Multiple fillers placed in brackets and separated by plus signs (e.g., >PA66-(GF25+MD15)<).
• Elastomers: Use ISO 1629 symbols (e.g., >EPDM<) and list main components by content order for vulcanized blends (e.g., >CR+NBR<).
• Marking method & durability:
  • Markings must be durable and readable on removed parts.
