Overview
ISO 3262-16:2023 is an international standard established by the International Organization for Standardization (ISO) that defines specifications and test methods specifically for aluminium hydroxides used as extenders. Extenders are materials added to products, such as pigments and fillers, to improve performance or reduce costs. This second edition updates the original 2000 release and introduces refined requirements to ensure quality and consistency in aluminium hydroxides, essential for industrial applications.
The standard focuses on aluminium hydroxides, primarily gibbsite (Al(OH)₃), including bayerite and boehmite forms, specifying their key physical and chemical properties. Compliance with ISO 3262-16:2023 guarantees that aluminium hydroxide extenders meet internationally recognized benchmarks for particle size, purity, pH, density, and other critical features.
Key Topics
Specifications for Aluminium Hydroxides
- Material Types: Includes both crystallized and ground aluminium hydroxides, with defined grades reflecting particle size and electrolyte content.
- Particle Size Distribution: Median particle size requirements vary by grade, ensuring suitability for specific industrial applications.
- Physical Properties: Parameters such as specific surface area, apparent density after tamping, and residue on sieves are standardized.
- Chemical Properties: pH of aqueous suspensions and resistivity of aqueous extracts set performance criteria.
- Volatile Matter Content: Limits on moisture and volatile compounds measured at 105 °C to ensure product stability.
Test Methods
- Utilizes internationally recognized test procedures like ISO 787 series for evaluating matters such as volatile content, pH, particle sieve residue, and resistivity.
- Methods encompass manual and instrumental analysis to accurately assess product conformity.
Sampling and Reporting
- Sampling is done per ISO 15528, which guarantees representative and reliable test samples.
- Detailed test reports are required, including identification, test results, compliance status, and any anomalies.
Conditional Requirements
- Lightness or brightness requirements for aluminium hydroxides are subject to agreement between parties, allowing flexibility based on end-use.
Applications
ISO 3262-16:2023 aluminium hydroxides are commonly used as extenders in:
- Paints and Coatings: Improve durability, texture, and opacity while optimizing cost.
- Rubber and Plastics: Enhance physical properties without compromising performance.
- Pigment and Dye Industries: Serve as fillers to modify characteristics and processing behavior.
- Chemical Manufacturing: Used in formulations requiring high purity and controlled particle size.
By adhering to this standard, manufacturers and quality control laboratories can ensure consistency, safety, and interoperability of aluminium hydroxide extenders across various industries worldwide.
Related Standards
ISO 3262-16:2023 references a range of complementary standards for testing and terminology, including:
- ISO 787 Series: A suite of test methods for pigments and extenders covering particle analysis, pH measurement, and other physical tests.
- ISO 5794-1: Addresses non-rubber tests for silica and hydrated precipitated materials, applicable for similar filler substances.
- ISO 15528: Specifies sampling procedures essential for accurate testing.
- ISO 18451-1: Provides terminology for pigments, dyestuffs, and extenders, ensuring consistent communication and definitions.
Compliance with ISO 3262-16:2023 alongside these related standards helps organizations maintain high-quality processes in manufacturing and testing aluminium hydroxide extenders.

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.
