SIST EN ISO 1043-1:2012/A1:2016 PDF

Overview

EN ISO 1043-1:2011/A1:2016 is a CEN-endorsed amendment to ISO 1043-1 (published 2011) that updates the standardized symbols and abbreviated terms used to identify basic polymers and their special characteristics. Published in 2016, this amendment introduces a new symbol ST for syndiotactic and a corresponding abbreviated term PS‑ST (polystyrene, syndiotactic). The change prevents duplication of abbreviations for materials with similar names and ensures consistent material identification across Europe and internationally.

Key topics and requirements

• Standardizes abbreviated terms (Clause 5) and symbols (Clause 6) used in polymer identification.
• Amendment A1 specifically adds:
  • Abbreviated term: PS‑ST - polystyrene, syndiotactic.
  • Symbol: ST - meaning syndiotactic.
• Ensures that national standards bodies adopt the amendment without modification (CEN adoption rules).
• Maintains ISO/TC 61’s editorial and technical conventions for material designation and documentation.
• Requires consistent use of the updated symbols in technical documentation, labeling, and material specifications to avoid ambiguity.

Practical applications

• Clear, unambiguous material labeling on product datasheets, packaging and technical drawings.
• Accurate material declarations for procurement, quality control and regulatory compliance.
• Improved material traceability in manufacturing, testing laboratories and recycling streams.
• Consistent terminology for specification sheets, bills of materials, and CAD/PDM systems where polymer type and tacticity (e.g., syndiotactic) are relevant.
• Useful in research and development where polymer microstructure (syndiotactic vs. isotactic/atactic) affects properties and needs standard coding.

Who should use this standard

• Plastics manufacturers and compounders
• Product designers and engineers specifying polymer grades
• Quality assurance and regulatory teams
• Testing laboratories and material characterization services
• Recyclers and waste management organizations needing reliable material identification
• Standards bodies and procurement officers ensuring consistent documentation

Related standards

• ISO 1043 series (other parts covering symbols/abbreviations for additives, fillers and other plastic-related designations)
• ISO/TC 61 “Plastics” technical committee publications
