ISO/TC 61/SC 1/WG 3 - Symbols

ISO 1043-3:2016 provides uniform symbols for components of terms relating to plasticizers to form abbreviated terms. It includes, in general, only those abbreviated terms that have come into established use. The purpose of ISO 1043-3:2016 is to prevent the occurrence of more than one abbreviated term for a given plasticizer. The symbols are primarily intended to be convenient shorthand for forming abbreviated terms for chemical names in publications and other written matter.

ISO 11469:2016 specifies a system of uniform marking of products that have been fabricated from plastics materials. Provision for the process or processes to be used for marking is outside the scope of this International Standard. NOTE 1 Precise details of the marking, e.g. the minimum size of the item to be marked, the size of the lettering, the appropriate location of the marking, are subject to agreement between the manufacturer and the user. The marking system is intended to help identify plastics products for subsequent decisions concerning handling, waste recovery or disposal. Generic identification of the plastics is provided by the symbols and abbreviated terms given in ISO 1043‑1, ISO 1043‑2, ISO 1043‑3 and ISO 1043‑4. NOTE 2 If more detailed information for material identification is needed, additional marking of plastics products can be applied as defined in the appropriate product standard. ISO 11469:2016 is not intended to supplant, replace or in any way interfere with the requirements for labelling specified in product standards or legislation.

ISO 1043-2:2011 specifies uniform symbols for terms referring to fillers and reinforcing materials. It includes only those symbols that have come into established use, and its main aim is both to prevent the occurrence of more than one symbol for a given filler or reinforcing material and to prevent a given symbol being interpreted in more than one way.

ISO 1043-1:2011 defines abbreviated terms for the basic polymers used in plastics, symbols for components of these terms, and symbols for special characteristics of plastics. It includes only those abbreviated terms that have come into established use and its aim is both to prevent the occurrence of more than one abbreviated term for a given plastic and to prevent a given abbreviated term being interpreted in more than one way. Guidance for the preparation of new abbreviated terms, reference lists of symbols for the components of plastics terms used to form the abbreviated terms for plastics, and a classification of abbreviated terms for polymers grouped by type are given in annexes.

Gives uniform abbreviated terms for plastics and symbols for components of these terms. It includes only abbreviated terms that have come into established use. Replaces the first edition.

Provides uniform symbols for components of terms relating to plasticizers for plastics in terms of abbreviations. Contains in general, only those abbreviations that have come into established use in practice. Replaces the first edition.
