Overview
EN 12904:2005 is a CEN standard that covers silica sand and silica gravel used for the treatment of water intended for human consumption. The document describes the relevant characteristics of these filter media, specifies requirements and the corresponding test methods, and provides information on their use in water treatment. EN 12904 helps ensure that silica-based media are suitable and safe for use in drinking‑water filtration and related processes.
Key Topics
- Scope and applicability: materials covered (silica sand and silica gravel) and intended use in drinking‑water treatment.
- Material characteristics: descriptive parameters such as grain size distribution, physical form, chemical purity, mechanical stability and absence of harmful contaminants (examples of typical characteristics a purchaser or tester will consider).
- Quality requirements: conformance criteria that suppliers and users must meet to ensure media performance and safety.
- Test methods: standardized procedures to verify compliance with the specified requirements (sampling, laboratory tests and performance checks).
- Guidance on use: practical information for selection, installation and maintenance of silica media in filtration and clarification systems.
Applications
EN 12904 is practical for professionals and organizations involved in:
- Water utilities and municipal treatment plants selecting and specifying filter media for drinking-water filtration.
- Filter media manufacturers and suppliers establishing quality control and demonstrating compliance to buyers.
- Laboratories and testing bodies performing standardized tests to verify media properties and safety.
- Consultants and engineers preparing technical specifications, procurement documents and design guidance for filtration systems.
- Regulators and procurement officers referencing harmonized criteria for public supply and infrastructure projects.
Benefits of using EN 12904 include improved reliability of filtration performance, consistent material quality, and reduced risk of introducing contaminants into drinking water through filter media.
Related Standards
EN 12904 complements other national and international standards and guidance on drinking‑water quality, water treatment chemicals, and filtration media. Users should consider EN 12904 alongside local drinking‑water regulations and additional CEN/ISO documents that cover specific testing, measurement procedures, or materials used in water treatment.
