Overview

EN 1208:2005 (CEN) defines requirements for sodium calcium polyphosphate used in the treatment of water intended for human consumption. The standard describes the product identity and physical properties, sets minimum purity criteria and limits for typical impurities and trace elements, and specifies corresponding test methods, sampling, labelling, transportation and storage information. EN 1208:2005 supersedes EN 1208:1997 and provides guidance while noting that national regulatory approval for use in drinking water remains the responsibility of authorities.

Key topics and technical requirements

  • Identification and composition
    • Chemical formula: (NaPO3)n · CaO (n typically ≈ 5)
    • Appearance: white glassy crystals or spheres
    • Solubility: ≈ 0.005 g/L at 25 °C
    • CAS: 23209-59-8; EINECS: 245-490-9
  • Composition (dry mass basis)
    • Phosphate (as P2O5): 61–69%
    • Sodium (as Na2O): 20–30%
    • Calcium (as CaO): 7–15%
  • Impurity limits
    • Sulfate (SO4 2–): ≤ 500 mg/kg
    • Fluoride (F–): ≤ 10 mg/kg
  • Trace element (chemical parameter) limits (mg/kg dry product)
    • Antimony (Sb) ≤ 3; Arsenic (As) ≤ 3; Cadmium (Cd) ≤ 3; Chromium (Cr) ≤ 10; Cyanide (CN–) ≤ 5; Lead (Pb) ≤ 10; Mercury (Hg) ≤ 1; Nickel (Ni) ≤ 10; Selenium (Se) ≤ 3
  • Test methods & sampling
    • Sampling: ISO 3165, ISO 6206 and ISO 8213 guidance
    • Main component analyses: ISO 3357 (P2O5), ISO 5373 (Ca), alkalimetric titration for Na2O (procedure provided)
    • Trace metals and elements: referenced EN/ISO methods (EN 1483, EN ISO 5961, EN ISO 11885, EN ISO 11969, ISO 8288, ISO 9174, ISO 9965, ISO 6703‑1, etc.)
  • Labelling / transportation / storage
    • Delivery means must be clean or dedicated to avoid contamination.
    • At publication date sodium calcium polyphosphate was not subject to EU hazard labelling; users must follow current national/EU regulations.

Applications and users

  • Practical use: corrosion control, sequestration and scale inhibition in potable water treatment systems (product information and recommended dosages are provided as guidance).
  • Typical users:
    • Water utilities and drinking water treatment operators
    • Chemical manufacturers and suppliers of water treatment products
    • Analytical laboratories performing conformity testing
    • Regulatory bodies and procurement/specification teams
