ISO 6472:2024

Overview

ISO 6472:2024 - Rubber compounding ingredients - Abbreviated terms (Sixth edition) defines clear, unambiguous abbreviated terms for commonly used rubber compounding ingredients of known, specific chemical composition. Prepared by ISO/TC 45, this edition updates the previous 2017 version by adding new ingredients and abbreviations and removing di‑tert‑butyl peroxide (DTBP) from Table 1. The document supplements trade names and trademarks by providing commonly used short forms, IUPAC names and CAS Registry Numbers (where available).

Key topics and technical requirements

• Scope and purpose: Establishes standardized abbreviated terms to avoid ambiguity in formulation documents, datasheets and technical communications.
• Notation conventions:
  • Abbreviations are derived from industry usage rather than a systematic nomenclature.
  • When an abbreviated term first appears in text, it must be enclosed in parentheses and preceded by the full chemical name.
  • IUPAC nomenclature and CAS RN are provided where possible; some reaction products are marked “not possible”.
  • Uses the letter P for phosphates (not F) to minimize confusion with fluorine compounds.
• Structured ingredient lists: The standard organizes abbreviated terms by functional groups, including:
  • Accelerators, co‑agents and vulcanizing agents
  • Activators and process aids
  • Vulcanization retarders
  • Antidegradants, antioxidants and antiozonants (including naming conventions for bisphenol antidegradants)
  • Plasticizers and softeners
  • Blowing agents
  • Isocyanates
• Reference content: Table 1 (and subsequent tables) pairs common chemical names with abbreviations, IUPAC names and CAS RN to promote consistent identification across industry documents.

Practical applications and users

Who benefits from ISO 6472:2024:

• Rubber chemists and compounders - for consistent notation in formulations and lab reports.
• R&D and formulation teams - to standardize ingredient lists and reduce misinterpretation.
• Quality, regulatory and procurement professionals - to harmonize specifications, procurement orders and compliance documents.
• Suppliers and data-sheet authors - to present ingredients with industry-recognized short forms and identifiers.
• Standards writers and technical editors - as a reference for unambiguous terminology in technical standards and guidance.

Practical uses:

• Standardizing ingredient abbreviations in technical datasheets, batch records and safety documentation.
• Improving clarity in international collaboration and supply‑chain communications.
• Reducing errors in formulation transfer and regulatory filings.

Related standards (if applicable)

• ISO 1043‑3 is noted for comparison regarding phosphate notation; ISO 6472:2024 intentionally adopts a different convention (P for phosphates) to avoid confusion with fluorine (F).
• Developed under the procedures described in the ISO/IEC Directives and maintained by ISO/TC 45 (Rubber and rubber products).
