Both ISO 1043-1 4th Edition, “Plastics – Symbols and abbreviated terms – Part 1: Basic polymers and their special characteristics,” and ISO 1043-2 3rd Edition, “Plastics – Symbols and abbreviated terms – Part 2: Fillers and reinforcing materials,” have just been released.
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.
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.
The other 2 standards in the series are:
- ISO 1043-3, Plastics – Symbols and abbreviated terms – Part 3: Plasticizers
- ISO 1043-4, Plastics – Symbols and abbreviated terms – Part 4: Flame retardants
Part 3 is scheduled for review and possible revision, Part 4 is stable.
