Overview
EN 1406:2017 (CEN) specifies requirements and test methods for modified starches used in the treatment of water intended for human consumption. The standard describes identification, composition, physical and chemical properties, purity criteria, sampling and analysis methods, and labelling/transport/storage instructions for starch-based water treatment chemicals (often called starch flocculants). It supersedes EN 1406:2009 and allows a wider possible degree of substitution for modified starch products.
Key topics and technical requirements
- Scope & applicability: Applies to modified starches used in potable water treatment; covers commercial forms (powder, granules, flakes, viscous aqueous solutions).
- Identification: Typical chemical types listed (non‑ionic, cationic, anionic, starch succinate) with empirical/chemical formulae and CAS numbers (e.g., non‑ionic starch 9005‑25‑8).
- Physical properties: Typical molecular mass range for undegraded potato derivatives (10^6–10^8), bulk densities for powders/granules and aqueous solutions, and solubility in hot/cold water (limited by viscosity).
- Chemical properties & hazards: Generally non‑hazardous but can react exothermically with strong oxidizers or acids; note potential interactions with disinfection/oxidizing agents in water.
- Purity and composition: Minimum purity criteria and limits on impurities are defined; composition of commercial products is specified.
- Test methods & sampling: References to analytical and sampling standards used for verification (e.g., EN ISO 1666, EN ISO 3696, EN ISO 5377, ISO 3165, ISO 6206, ISO 8213).
- Labelling, transport, storage: Requirements for delivery format, EU labelling, transport regulations and shelf‑life/stability guidance are included.
- Informative Annex: Practical information on raw materials, manufacturing, dosing, application methods, removal of excess product, handling and emergency procedures.
Practical applications
- Use this standard when specifying, procuring, testing or approving modified starch flocculants for drinking-water treatment processes such as clarification, flocculation and sludge handling.
- Helpful for quality control of supplied products, conformity checks, and ensuring compatibility with disinfection regimes.
Who should use this standard
- Water utilities and treatment plant operators
- Chemical manufacturers and suppliers of modified starches
- Analytical laboratories performing compliance testing
- Regulatory bodies and procurement teams
- Consultants and designers specifying coagulant/flocculant chemicals
Related standards and notes
- Normative references within EN 1406:2017: EN ISO 1666, EN ISO 3696, EN ISO 5377, ISO 3165, ISO 6206, ISO 8213.
- Note: Conformity with EN 1406:2017 does not automatically guarantee national regulatory approval; national rules may still apply.
