Overview
EN 12912:2012 (CEN) is the European standard for barite (barium sulfate, BaSO4 - CAS 13462-86-7) used in the treatment of water intended for human consumption. The document describes product identification, physical and chemical characteristics, performance requirements, and the test methods and labelling rules needed to support safe use of barite as a filtration or support medium in drinking-water treatment systems.
Key topics and technical requirements
- Identification and composition
- Chemical name: Barium sulfate (BaSO4); common names: barite, baryte.
- Minimum BaSO4 content: typically specified (commercial requirement: BaSO4 ≥ 92%).
- Acid‑soluble material: limited (max 3%).
- Particle size and grading
- Particle size distribution determined per EN 12902.
- Particle sizing options: effective size (d10) with ±5% tolerance, uniformity coefficient U < 1.5, or defined particle-size ranges with permitted oversize/undersize mass fractions:
- Multimedium filtration layer: ≤ 5% oversize/undersize
- Single medium filters: ≤ 10%
- Support layer: ≤ 15%
- Physical properties
- Bulk density (loose): 2 200–2 400 kg/m3
- Bulk density (packed): 2 500–2 600 kg/m3
- Absolute/particle density: typically 4.2–4.5 g/cm3
- Chemical safety and leaching
- Low solubility of BaSO4 (solubility product KS ≈ 1.07×10^-10 at 25 °C); correctly used granular barite should not significantly raise barium in treated water after filling, washing and commissioning.
- Testing and sampling
- Test methods and sampling reference EN 12902 and EN ISO 3696 for laboratory water quality.
- Gravimetric method for BaSO4 content and standard procedures for particle size, bulk density and acid‑soluble matter are described.
- Labelling, transport and storage
- Marking must include product name/grade, net mass, supplier/manufacturer details and “This product conforms to EN 12912”.
- Barite is not classified as dangerous for transport (no UN number) and has unlimited storage stability.
Applications and users
- Primary use: filtering and supporting material in open or closed multilayer drinking-water filters.
- Typical users:
- Water utilities and treatment plant operators
- Filter media manufacturers and suppliers
- Testing laboratories and conformity assessors
- Regulatory and procurement bodies specifying media for potable water systems
- Practical notes:
- Check national regulations before use - conformity with EN 12912 does not automatically imply national approval.
- Notify users/authorities if production changes introduce significant impurities or additives.
