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 documents 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 ).

The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee SC 3, Raw materials (including latex) for use in the rubber industry.

This fifth edition cancels and replaces the fourth edition (ISO 7663:2005), which has been technically revised with the following changes:

• Clause 2 has been updated;
• 4.2, the method given in ISO 248-2 is now allowed;
• 5.2.2.1, addition of a statement that the mixing with a laboratory internal mixer is the preferred procedure. Method B becomes “Single stage mixing with a laboratory internal mixer”;
• 5.2.2.3, advice on mixing with various sizes of laboratory internal mixer is given along with a general mixing procedure.

1 Scope

This International Standard specifies the following:

• physical and chemical tests on raw rubbers;
• standardized materials, a standardized test formulation, and the equipment and processing methods for evaluating the vulcanization characteristics of all types of halogenated isobutene-isoprene rubber (BIIR and CIIR).
