Overview
EN 1204:2005 is the CEN European standard for calcium tetrahydrogen bis(orthophosphate) (common name: monocalcium phosphate, Ca(H2PO4)2) when used for the treatment of water intended for human consumption. The standard defines product identity, physical and chemical properties, minimum purity criteria, required test methods, labelling, transportation and storage information, and guidance on use in drinking-water treatment (noting national regulatory control may apply).
Key topics and technical requirements
- Identification and properties
- Chemical name: calcium tetrahydrogen bis(orthophosphate); CAS 7758-11-4; EINECS 231-837-1.
- Form: white powder, bulk density 500–800 g/dm3; solubility ≈ 0.005 g/L at 25 °C; 10% suspension pH ≈ 3.
- Composition requirements (dry basis)
- Phosphate (as P2O5): (56 ± 2.0) %
- Calcium (as CaO): (23 ± 2.0) %
- Impurity limits
- Sulfate (SO4 2–): ≤ 500 mg/kg
- Fluoride (F–): ≤ 10 mg/kg
- Trace element limits (mg/kg dry product): Antimony ≤ 3, Arsenic ≤ 3, Cadmium ≤ 3, Chromium ≤ 10, Cyanide ≤ 5, Lead ≤ 10, Mercury ≤ 1, Nickel ≤ 10, Selenium ≤ 3.
- Test and sampling methods
- Sampling per ISO 3165 / ISO 6206 / ISO 8213.
- Main analyses: P2O5 (ISO 3357); CaO (ISO 5373).
- Impurities: sulfate (ISO 2997); fluoride (ISO 3360).
- Trace elements: AAS/ICP methods referenced (EN ISO 11885, EN ISO 5961, ISO 9174, EN ISO 11969, EN 1483, etc.). Specific sample preparation and calculation formula provided.
- Labelling and packaging
- Required marking: chemical name/trade name/grade, net mass, supplier address, statement “this product conforms to EN 1204”.
- Storage & transport
- Not classified as dangerous for transport; no UN number. Store in plastics, avoid contact with metals; stable ≥1 year in closed containers.
Applications and practical use
- Primary application: corrosion inhibition in drinking-water distribution systems (cast iron, steel, copper).
- Formulation/use: applied as a non-defined suspension and dosed via metering pumps.
- Typical dosing guidance in the standard: ensure phosphate in treated water ≤ 5 mg/L (expressed as P2O5).
- Users should assess national regulations and raw-water quality when selecting product grades and dosing.
Who uses EN 1204:2005
- Water utilities and distribution system operators
- Chemical manufacturers and suppliers of phosphate products
- Drinking-water treatment consultants and engineers
- Analytical laboratories performing conformity testing
- Regulatory authorities assessing product acceptance for potable water use
