Overview

SIST EN ISO 3262-7:2023 is the Slovenian adoption of the international standard ISO 3262-7:2023, prepared by the International Organization for Standardization (ISO) and adopted by the European Committee for Standardization (CEN). This standard specifies the requirements and corresponding test methods for dolomite used as an extender in industrial applications, particularly in the production of paints, coatings, plastics, and related materials. Dolomite, a naturally occurring calcium magnesium carbonate, serves as a pigment extender and functional filler in various industries.

Key Topics

• Product Requirements
  • Defines essential chemical and physical property requirements for dolomite in extender applications.
  • Specifies minimum content levels, moisture content, loss on ignition, and permissible insoluble matter.
• Testing Methods
  • Includes standardized methods for sampling, analysis, and quality assessment.
  • Testing covers aspects such as volatility, solubility, pH, residue on sieve, particle size distribution, and lightness.
• Quality Grades
  • Provides grading system for dolomite based on pure content and specific property thresholds, allowing users to select suitable material for their needs.
• Reporting Criteria
  • Describes mandatory items for test reporting to ensure traceability and compliance with the standard.

Applications

Dolomite as specified in SIST EN ISO 3262-7:2023 is widely utilized as an extender or filler in many manufacturing sectors, offering several advantages:

• Paints and Coatings
  • Improves bulk, optimizes cost, and modifies gloss and opacity characteristics of finished coatings.
• Plastics Industry
  • Acts as a filler to enhance mechanical properties and control production costs.
• Construction Materials
  • Used in adhesives, sealants, and plasters where defined particle size and purity contribute to product consistency and quality.
• Other Industrial Uses
  • Assists in ceramics, paper production, and agricultural products due to its defined mineralogical composition and reliable performance.

Using dolomite that meets standardized specifications ensures product consistency, safety, and optimal performance across these sectors, helping manufacturers meet regulatory and customer requirements.

Related Standards

To fully implement the requirements and testing methods in SIST EN ISO 3262-7:2023, familiarity with related standards is essential:

• ISO 3262-1: Extenders - Specifications and methods of test - Part 1: Introduction and general test methods
• ISO 787 Series: General methods of test for pigments and extenders, including:
  • ISO 787-2: Determination of matter volatile at 105 °C
  • ISO 787-3: Determination of matter soluble in water
  • ISO 787-7: Determination of residue on sieve
  • ISO 787-9: Determination of pH value of an aqueous suspension
  • ISO 787-14: Determination of resistivity of aqueous extract
• ISO 8130-13: Coating powders - Particle size analysis by laser diffraction
• ISO 15528: Sampling of paints, varnishes, and raw materials
• ISO 18451-1: Terminology for pigments, dyestuffs, and extenders

By aligning with SIST EN ISO 3262-7:2023 and these associated standards, organizations benefit from internationally recognized quality, safety, and interoperability in the use of dolomite as an extender. This contributes to higher efficiency, reduced waste, and improved market competitiveness in industries relying on pigments and fillers.
