Overview
SIST EN ISO 3262-18:2023 provides internationally harmonized specifications and standardized test methods for precipitated sodium aluminium silicate, an important industrial extender. As Part 18 of the ISO 3262 series, this standard ensures quality consistency in raw materials used as extenders across various sectors, primarily in paints, coatings, plastics, and other composite materials. Developed by the international technical committees for pigments and extenders, the document describes both the necessary requirements for product quality and the accepted methods for sampling and laboratory analysis.
Key Topics
- Scope and Coverage
- Specifies the minimum quality standards for precipitated sodium aluminium silicate.
- Defines test methods for verifying compliance with these standards.
- Essential Product Requirements
- Includes key characteristics such as silica content, aluminium oxide and sodium oxide content, pH value, oil absorption, particle size, and residue on sieve.
- Test Methods
- Outlines precise analytical methods including gravimetric analysis, spectrometry (such as FAAS and ICP-AES), and standardized procedures for determining physical and chemical properties.
- Terminology
- Incorporates up-to-date definitions and references core terminology from ISO 18451-1 for consistency.
- Sampling Procedures
- Provides detailed guidance on correct sampling to ensure representative test results.
Applications
Precipitated sodium aluminium silicate finds extensive application as a functional filler or extender due to its performance and cost benefits. Following SIST EN ISO 3262-18:2023 helps industries and suppliers in several ways:
- Paints and Coatings
- Used to improve coverage, regulate sheen, and enhance physical properties in architectural and industrial paints.
- Plastics and Polymers
- Functions as a reinforcing filler for improved strength and stability in thermoplastics and thermosets.
- Rubber Compounding
- Incorporated as a performance additive in rubber products, often alongside silica-based reinforcing agents.
- Ink and Paper
- Provides control over viscosity and opacity in specialty printing inks and paper formulations.
- Quality Assurance
- Regular application of the standard’s test methods ensures ongoing product quality and facilitates international trade.
- Research and Development
- Enables R&D teams to benchmark and improve extender formulations for new products.

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

This second edition cancels and replaces the first edition (ISO 3262-18:2000), which has been technically
revised.
The main changes are as follows:
