Overview
EN 1210:2005 is the CEN (European) standard that specifies requirements for sodium tripolyphosphate (STPP) when used as a chemical for the treatment of water intended for human consumption. The document defines identification and physical/chemical properties, minimum purity criteria, impurity limits, required test methods and guidance on labelling, transportation and storage. It applies to STPP in both solid (white powder or granules) and liquid (clear solution) commercial forms and replaces EN 1210:1997.
Key identification facts from the standard:
- Chemical name: Sodium tripolyphosphate (Na5P3O10)
- Relative molecular mass: 368.0
- CAS: 7758-29-4; EINECS: 231-838-7
- Typical solubility: ~150 g/L at 25 °C; 1% solution pH ≈ 9.5
Key topics and requirements
- Scope & applicability: Specifies STPP characteristics and uses for drinking-water treatment; notes that national regulations may impose additional restrictions.
- Composition: Required main-product content on a dry-mass basis:
- Phosphate (as P2O5): (57 ± 2.0) %
- Sodium (as Na2O): (42 ± 1.0) %
- Impurity limits (mg/kg dry product):
- Sulfate (SO4 2–): max 500
- Fluoride (F–): max 10
- Trace chemical parameter limits (mg/kg):
- Antimony, Arsenic, Cadmium, Selenium: max 3 each
- Chromium, Lead, Nickel: max 10 each
- Cyanide: max 5; Mercury: max 1
- Test methods & sampling:
- Sampling standards referenced (e.g., ISO 3165, ISO 8206/8213) and detailed sampling procedures for solids, drums, tanks and tankers.
- Analytical methods cited for determinations: ISO 3357 for phosphate, alkalimetric titration for Na2O, ISO 2997 for sulfate, ISO 3360 for fluoride, and atomic absorption/ICP methods (EN/ISO references) for metals and metalloids.
- Labelling/transport/storage: Requirements and practical handling guidance are included.
Applications and users
Who uses EN 1210:2005:
- Water utilities and municipal drinking-water authorities evaluating STPP for treatment use
- Chemical manufacturers and suppliers of sodium tripolyphosphate and dosing formulations
- Analytical laboratories performing compliance testing and quality control
- Regulators and procurement teams assessing product acceptance for potable water treatment
Practical value:
- Ensures consistent product quality, safety and trace-contaminant limits for STPP used in drinking-water systems.
- Provides harmonized test methods and sampling procedures for reliable quality control and regulatory compliance.
