Chemicals used for treatment of water intended for human consumption - High-calcium lime

This European Standard is applicable to high-calcium lime used for treatment of water intended for human consumption. It describes the characteristics of high-calcium lime and specifies the requirements and the corresponding test methods for high-calcium lime. It gives information on its use in water treatment. It also determines the rules relating to safe handling and use (see Annex B).

Overview

EN 12518:2014 (CEN) is the European standard for high-calcium lime used in the treatment of water intended for human consumption. It describes the identity and commercial forms of high-calcium lime (calcium oxide CaO, calcium hydroxide Ca(OH)2, and milk of lime), specifies quality and purity requirements, references test methods and sampling, and gives guidance on labelling, transportation, storage and safe handling (Annex B). This edition supersedes EN 12518:2008 and aligns safety labelling with Regulation (EC) No 1272/2008 (CLP).

Key Topics and Requirements

• Scope & Description: Identification (CAS, formulas), physical properties (density, solubility ranges for Ca(OH)2), and commercial forms - powdered, lump, hydrated lime and suspensions.
• Purity criteria & Grades: Product grades/classes set minimum active content (e.g., water‑soluble CaO ≥ 87% for top class) and particle-size/retention limits for powders.
• Impurities & water‑insoluble matter: Limits for common impurities (Si as SiO2, Al as Al2O3, Fe as Fe2O3, Mn, CaCO3) and water‑insoluble fractions are specified by grade.
• Trace chemical parameters: Maximum concentrations for trace metals (e.g., As, Cd, Cr, Hg, Ni, Pb, Sb, Se) are defined to protect drinking water quality.
• Test methods & sampling: Analytical and sampling procedures are referenced to EN 12485 to ensure consistent laboratory testing.
• Labelling & CLP: Hazard pictograms, signal words and standard hazard statements (H318, H315, H335) are required under EU CLP rules; Extended Safety Data Sheets (eSDS) and P‑statements are expected.
• Transport & storage: Transport classifications are given (e.g., CaO UN 1910; IMDG/IATA class 8, PG III), together with storage incompatibilities and shelf‑stability guidance.

Practical Applications and Users

EN 12518:2014 is used by:

• Water utilities and treatment plant operators specifying and accepting high‑calcium lime for drinking‑water processes.
• Chemical manufacturers and suppliers to declare product quality, grades and labelling compliance.
• Analytical laboratories performing acceptance and compliance testing (per EN 12485).
• Regulators and procurers assessing conformity for distribution and use in potable water systems. Practical value: ensures consistent product quality, safe handling/transport, and traceability of impurities that could affect drinking-water safety.

Related Standards and Legislation

• EN 12485 - test methods and sampling for calcium‑based treatment chemicals
• Regulation (EC) No 1272/2008 (CLP) - classification and labelling requirements
• Directive 98/83/EC - drinking water quality context (referenced for trace metal implications)
• EN 12518:2008 - previous edition (superseded)

For specification, procurement or compliance tasks involving high‑calcium lime in drinking‑water treatment, EN 12518:2014 is the authoritative reference for product quality, testing and safety practices.
