Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products.
This sixth edition cancels and replaces the fifth edition (ISO 6472:2017), which has been technically revised.
The main changes are as follows:
— new ingredients and their abbreviations have been added;
— di-tert-butyl peroxide (DTBP) has been removed from Table 1 due to its high risk of ignition in rubber
applications.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Rubber compounding ingredients — Abbreviated terms
1 Scope
This document establishes unambiguous abbreviated terms for commonly used rubber compounding
ingredients of known, specific chemical composition.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
4 Notation conventions used in this document
4.1 The abbreviated terms are derived from common usage in industry and commerce rather than from
any systematic nomenclature. The list is not intended to conflict with, but rather to act as a supplement to,
existing trade names and trademarks.
4.2 When abbreviated terms first appear in a text, they shall be enclosed in parentheses and shall be
preceded by the chemical name written in full.
4.3 The list does not purport to be comprehensive, and abbreviated terms for other compounding
ingredients will be added in future revisions of this document.
4.4 International Union of Pure and Applied Chemistry (IUPAC) nomenclature is provided where this
is available, in addition to the commonly used chemical name or names. In some instances, alternative
commonly used chemical names are given where they are recognized. For those materials whose chemical
formula cannot be specified, such as reaction products or polymerized products, the identification of
IUPAC is “not possible”. Chemical Abstracts Service Registry Number (CAS RN) is also provided unless “not
available”.
4.5 Unlike ISO 1043-3, which uses the letter F for phosphates, this document uses the letter P, because
P is used universally to designate phosphates and other phosphorous compounds and the letter F is used
universally to designate fluorine and its compounds; this usage would thus minimize the confusion among
those using this document.
