DIN ISO 14359:1997-09

The document specifies the marking of all separable parts made of polymer material (plastic), which are used in wintersport equipment (e.g. ski boots, ski-bindungs). It is not applicable for component materials with duroplastic components (e.g. skis). It lays down minimum requirements for identifying of material. This shall provide the precondition for a type-pure separation of polymer materials to enable recycling.
