Overview

EN 882:2016 (CEN) specifies requirements for sodium aluminate when used in the treatment of water intended for human consumption. Approved by CEN in January 2016, this European Standard supersedes EN 882:2004 and covers identification, properties, purity criteria, analytical methods, guidance for use in water treatment, and rules for safe handling (Annex B).

Key SEO terms: EN 882:2016, sodium aluminate, water treatment, drinking water, CEN, chemical safety.

Key topics and technical requirements

• Scope and applicability: Applies to sodium aluminate used for drinking-water treatment; provides characteristic definitions and references to analytical methods.
• Identification and composition:
  • Chemical names: aluminium sodium oxide / aluminium sodium dioxide / aluminium sodium tetrahydroxide.
  • Common name: sodium aluminate.
  • CAS numbers: 1302-42-7; 12251-53-5. EINECS: 215-100-1; 235-487-0.
• Commercial forms: Solids (powder, granules) and aqueous solutions (colourless to yellow).
• Physical properties:
  • Solid absolute density: 2.35 g/cm3; tamped bulk density (powder) ~1.0–1.2 g/cm3.
  • Solution density: ~1.5 g/ml for 10 % Al (mass fraction of aluminium).
  • Solubility: soluble in water up to ~12.7 % Al at 20 °C; hydrolysis and precipitation may occur with dilution/temperature changes.
  • Viscosity examples: at 20 °C, ~120 mPa·s for 10 % Al and ~560 mPa·s for 12.7 % Al solutions (viscosity increases at lower temperatures).
• Purity and impurities: The standard defines purity criteria, allowable impurities and chemical parameters for commercial products.
• Test methods and sampling: References and requirements for sampling solids and liquids and for analytical testing (normative references).
• Labelling, transport and storage: Requirements in accordance with EU labelling rules (Regulation (EC) No 1272/2008), transportation regulations, marking and storage conditions, including long-term stability and incompatibilities.
• Safety: Annex B contains rules for safe handling, emergency procedures for spills, accidents and fires.

Applications and who uses it

• Practical use: Standard applies where sodium aluminate is supplied, specified, or tested for treatment of drinking water - including formulation control, delivery and on-site handling.
• Typical users:
  • Water utilities and water treatment plant operators
  • Chemical suppliers and manufacturers of treatment chemicals
  • Test laboratories and quality control analysts
  • Regulatory bodies and procurement specialists
  • Environmental and safety officers responsible for storage, transport and emergency response

Related standards

• EN 1302 - Aluminium-based coagulants - Analytical methods
• ISO 3165, ISO 6206, ISO 8213 - Sampling standards for chemical products

EN 882:2016 is a practical reference for ensuring sodium aluminate quality, safe use and regulatory compliance in drinking-water treatment operations.
