ISO 11469 specifies a uniform marking system for products fabricated from plastic materials. But precise details of the marking, e.g. the minimum size of the item to be marked, the size of the lettering, and the appropriate location of the marking, these terms depend on the agreement between the manufacturer and the user.
The marking system is intended to help identify plastic products for subsequent decisions concerning handling, waste recovery or disposal. The symbols and abbreviated terms in ISO 1043-1, ISO 1043-2, ISO 1043-3 and ISO 1043-4 help identify different types of plastics.
If more detailed information for material identification is needed, additional marking of plastic products can be applied. ISO 11469 is not intended to supplant, replace, or interfere with the requirements for labelling specified in product standards or legislation.
The text of ISO 11469:2016 has been approved in Europe as EN ISO 11469:2016 without any changes.
