Overview
EN 16004:2011 (CEN) is the European standard for magnesium oxide used in the treatment of water intended for human consumption. It defines the product identification, physical and chemical characteristics, minimum purity criteria, required test methods, labelling, transport and storage rules, and provides practical information on use in water treatment (Annex A). The standard does not replace national regulations or regulatory approval - conformity addresses product specification, not legal acceptance in individual Member States.
Key topics and technical requirements
- Identification
- Chemical name: magnesium oxide (MgO), CAS 1309-48-4, formula MgO, relative molecular mass 40.31.
- Physical properties
- Grey granular material; density 3.6 g/cm3 (20 °C); bulk density 1.1–1.3 g/cm3; solubility ~0.0062 g/L at 20 °C.
- Available in various granular particle-size ranges depending on application.
- Composition and purity
- MgO content (dry): > 70%
- Loss on ignition (CO2 and H2O): < 25%
- Impurity limits (mass %)
- CaO / Ca(OH)2 (free): max 5%
- SiO2: max 2%
- Al2O3: max 1%
- Fe2O3: max 2%
- Trace chemical parameters (mg/kg, dry)
- Antimony (Sb): ≤ 3; Arsenic (As): ≤ 3; Cadmium (Cd): ≤ 2; Chromium (Cr): ≤ 10; Lead (Pb): ≤ 10; Mercury (Hg): ≤ 0.5; Nickel (Ni): ≤ 10; Selenium (Se): ≤ 3.
- Testing and sampling
- Sampling: follow ISO 3165 and ISO 6206; analyses: methods referenced in EN 12485.
- Labelling, transport, storage
- Marking must include product name/grade, net mass, supplier/manufacturer and the statement “this product conforms to EN 16004.”
- Not classified as dangerous goods at date of publication; no general EU hazard labelling required then.
- Store dry (indefinite stability if dry); keep away from acids; deliver in bags, containers or bulk (cleaned containers required).
Applications and practical value
- Primary uses: pH adjustment and hardness control in drinking-water treatment, and neutralization of mineral acids.
- Provided guidance on form, particle sizes and application methods (Annex A) to aid selection of the appropriate granular grade and dosing strategy.
- Helps manufacturers, suppliers and water utilities ensure consistent product quality and compatibility with treatment processes and regulatory monitoring.
Who should use EN 16004:2011
- Water treatment plant operators and engineers
- Chemical suppliers and manufacturers of magnesium oxide
- Laboratories performing acceptance testing and compliance analysis
- Procurement teams specifying chemicals for drinking water
- Regulatory bodies and consultants evaluating product suitability
Related standards and references
- EN 12485 (test methods for related chemicals)
- ISO 3165, ISO 6206 (sampling)
- REACH (Regulation (EC) No 1907/2006) and national drinking water regulations for legal compliance
