Overview
EN 888:2023 - published by CEN - is the European standard that specifies requirements for iron (III) chloride (ferric chloride) when used for the treatment of water intended for human consumption. It applies to two commercial forms:
- Iron (III) chloride solution (ferric chloride solution; FeCl3, Mw 162.21 g·mol−1), and
- Iron (III) chloride hexahydrate (FeCl3·6H2O, Mw 270.31 g·mol−1), a yellow, hygroscopic crystalline granulate.
The standard describes identification, physical and chemical properties, product grades and types, labelling, storage, transportation and rules for safe handling and use. EN 888:2023 supersedes EN 888:2004 and incorporates updates to safety labelling and alignment with current drinking-water regulation considerations.
Key topics and technical requirements
- Scope and identification: chemical names, CAS numbers (7705-08-0 for FeCl3 solution; 10025-77-1 for the hexahydrate), empirical and chemical formulas.
- Physical properties: e.g., 40 % FeCl3 solution density ≈ 1.43 g·cm−3 at 20 °C; hexahydrate density ≈ 1.8 g·cm−3; hexahydrate melting point ~37 °C; hexahydrate solubility up to ~47 % FeCl3 mass fraction at 20 °C.
- Composition and purity criteria: requirements for commercial grades and types used in drinking-water treatment.
- Analytical methods: analytical methods were removed from this edition and are now provided via the referenced normative standard EN 17215 (Iron‑based coagulants - Analytical methods).
- Labelling, transport and storage: mandates on EU risk/safety labelling, transport regulations and storage precautions (including long‑term stability and incompatibilities).
- Safety and emergency procedures: Annex B provides general rules for safe handling, first aid, spillage and fire response.
Practical applications
EN 888:2023 is a practical reference for the use of ferric chloride in drinking‑water treatment processes such as coagulation/flocculation and related removal of turbidity and contaminants (document provides guidance on use form, dosing and application methods in Annex A). The standard helps ensure product consistency, safe handling, regulatory compliance and traceability.
Who should use this standard
- Water utilities and treatment plant operators
- Chemical manufacturers and suppliers of ferric chloride (solution and hexahydrate)
- Quality assurance and analytical laboratories testing water‑treatment chemicals
- Procurement officers, regulatory authorities and safety officers responsible for labeling, transport and storage
