Overview

EN ISO 3262-10:2024 defines the specifications and test methods for extenders based on natural talc/chlorite in lamellar form. As part of the ISO 3262 series, this standard provides key requirements for quality, composition, and properties relevant to naturally occurring talc/chlorite mixtures used as extenders. The document details grading, essential product characteristics, and test procedures for these materials, supporting consistency, safety, and regulatory compliance across industries.

EN ISO 3262-10:2024 replaces the previous version (EN ISO 3262-10:2000), introducing updated methods and requirements in line with current analytical practices. This standard is essential for manufacturers, quality assurance professionals, and end-users across sectors where extenders play a critical role in formulations.

Key Topics

• Scope and Application: Specifies requirements for naturally occurring talc/chlorite in lamellar form, including mineralogical grading (A, B, C, D) based on talc and chlorite content.
• Essential Requirements: Covers minimum talc/chlorite content, loss on ignition, volatile matter, water-soluble matter, pH of aqueous suspension, quartz content, and detection of asbestos fibers.
• Test Methods: Standardized procedures such as X-ray diffraction, SEM/EDX or TEM for asbestos analysis, and ISO-referenced methods for residue, pH, and particle size distribution.
• Conditional and Additional Properties: Includes optional test parameters like particle size distribution, residue on sieve, color, lightness, and resistivity; these are typically agreed upon between supplier and customer.
• Test Reporting: Outlines necessary information for test reports to ensure traceability and clarity, including reference to the standard and any deviations from prescribed methods.

Applications

Natural talc/chlorite extenders in lamellar form addressed by EN ISO 3262-10:2024 find application in a range of industries where reliable performance and material consistency are critical, including:

• Paints and Coatings: Used as functional fillers to enhance mechanical properties, improve coverage, and optimize rheology in architectural and industrial coatings.
• Plastics and Polymers: Improves dimensional stability and processing characteristics in thermoplastics and thermosets.
• Rubbers and Elastomers: Provides reinforcement, improves mixing, and controls viscosity in rubber compounding.
• Paper and Pulp: Functions as a filler and coating pigment, enhancing smoothness, printability, and opacity.
• Other Industrial Uses: Deployed in ceramics, sealants, and adhesives for property enhancement and cost optimization.

Manufacturers and product developers rely on compliance with EN ISO 3262-10:2024 to meet regulatory requirements and customer specifications for extender products.

Related Standards

EN ISO 3262-10:2024 is one part of a comprehensive family of standards for pigments and extenders. Key related standards include:

• ISO 3262-1: Introduction and general test methods for extenders
• ISO 787 series: General test methods for pigments and extenders, including tests for volatile matter, water solubility, residue on sieve, pH, and resistivity
• ISO 3262-2:2023: Specifications for baryte (natural barium sulfate)
• ISO 8130-13: Particle size analysis by laser diffraction
• ISO 14966: Determination of inorganic fibrous particle concentrations using electron microscopy
• ISO 18451-1: Terminology for pigments, dyestuffs, and extenders

Implementing EN ISO 3262-10:2024 ensures compatibility with global quality frameworks, aligns with customer demands, and encourages uniform practices in the testing and classification of talc/chlorite 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.
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 docum
