Overview
EN 16409:2013 (CEN) is the European standard for dolomitic lime used in the treatment of water intended for human consumption. It defines identification, physical and chemical characteristics, purity criteria, allowable impurities and trace elements, test methods and labelling. The standard also provides practical information on use in water treatment and rules for safe handling and emergency procedures (Annex B). Note: conformity with EN 16409:2013 does not automatically guarantee national regulatory acceptance; local regulations may still apply.
Key topics and requirements
- Scope and identification
- Chemical names, synonyms, CAS and EINECS references and empirical/chemical formulas for dolomitic lime (e.g., Ca(OH)2MgO / CaOMgO).
- Physical and chemical properties
- Commercial forms: coarse material or powder; delivery in bags, containers or bulk.
- Specified densities and bulk densities, and solubility values (e.g., ~1 000 mg/L for CaMg(OH)2 and ~1 385 mg/L for CaMgO2 at 20 °C).
- Aqueous suspensions are strongly alkaline; reactions with water/acids are exothermic.
- Purity and composition
- Major-constituent requirements: CaO + MgO ≥ 90% (dry, bound-water free); MgO ≥ 30%.
- CO2 content ≤ 5%.
- Particle size/retention limits on sieving (specified mm thresholds).
- Impurities and chemical parameters
- Limits for mineral impurities (SiO2, Al2O3, Fe2O3, MnO2) and trace elements:
- Arsenic ≤ 5 mg/kg, Cadmium ≤ 2 mg/kg, Chromium ≤ 20 mg/kg, Mercury ≤ 0.3 mg/kg, Nickel ≤ 20 mg/kg, Lead ≤ 10 mg/kg, Antimony ≤ 3 mg/kg, Selenium ≤ 3 mg/kg.
- Limits for mineral impurities (SiO2, Al2O3, Fe2O3, MnO2) and trace elements:
- Test methods and sampling
- Sampling and analytic methods referenced to EN 12485.
- Labelling and transport
- Labelling to EU CLP Regulation (Reg. 1272/2008); hazard pictogram GHS05 (corrosive) shown where applicable.
- Safety
- Annex B specifies handling, storage, incompatibilities and emergency procedures.
Applications and users
- Primary application: treatment of drinking water (water intended for human consumption).
- Typical users:
- Water utilities and treatment plant operators
- Chemical manufacturers and suppliers of dolomitic lime
- Testing laboratories and QA/QC personnel
- Regulatory bodies and procurement teams specifying water-treatment chemicals
- Environmental and process engineers
Related standards
- EN 12485 - referenced for sampling and test methods for calcium/magnesium lime products.
- EU Regulation No 1272/2008 (CLP) - for labelling and classification requirements.
