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 ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

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 third edition cancels and replaces the second edition (ISO 5794-2:1998), which has been technically revised with the following changes:

• ISO 5794-3 is now mentioned in the scope;
• normative references have been updated;
• those standards which refer to the ingredients of the standard test formulations have been moved to the new section “Bibliography”;
• footnote 1 in Table 1 has been deleted because SBR 1500 EST is no longer available.

ISO 5794 consists of the following parts, under the general title Rubber compounding ingredients — Silica, precipitated, hydrated:

• Part 1: Non-rubber tests
• Part 2: Evaluation procedures in styrene-butadiene rubber
• Part 3: Evaluation procedures in a blend of solution styrene-butadiene rubber (S-SBR) and butadiene rubber (BR)

1 Scope

This part of ISO 5794 specifies the test formulation, equipment, procedure, and test methods for determining the physical properties of precipitated hydrated silica in a styrene-butadiene rubber mix.

ISO 5794-1 describes methods for chemical analysis of precipitated hydrated silica, describes its physical and chemical properties, and classifies silica with respect to their specific surface area obtained by nitrogen adsorption.

ISO 5794-3 specifies the test formulation, equipment, procedure, and test methods for determining the physical properties of precipitated hydrated silica in a compound based on a blend of solution styrene-butadiene rubber and butadiene rubber.

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
