Overview
EN 16038:2012 is a CEN European Standard that specifies requirements for sodium hydrogen sulfate (sodium bisulfate) used to treat swimming pool water. The standard describes identification, physical and chemical properties, minimum purity criteria, impurity limits, required test methods and practical information on labelling, transportation and storage. EN 16038:2012 helps manufacturers, suppliers and pool operators ensure the quality and safe use of sodium hydrogen sulfate for pH adjustment in swimming pools.
Key Topics and Requirements
- Identification and properties
- Chemical name: sodium hydrogen sulfate (synonym: sodium bisulfate); empirical formula NaHSO4; relative molecular mass 120.06 g·mol‑1; CAS 7681‑38‑1.
- Commercial form: powder or beads, free‑flowing. Hygroscopic; aqueous solutions are strongly acidic (a 20% solution has pH ≈ 1–1.2).
- Solubility: ≈1 080 g/L at 25 °C.
- Purity and composition
- Minimum NaHSO4 content: > 92% (mass fraction).
- Impurities (Table 1): sodium sulfate ≤ 8%, water ≤ 0.8%, water‑insoluble substances ≤ 0.05%, iron ≤ 0.01%.
- Chemical parameter limits (mg/kg NaHSO4)
- As, Cd, Hg ≤ 0.1; Cr, Ni, Pb, Sb, Se ≤ 1 (other values as specified in the standard).
- Test methods
- Analytical and sampling methods reference EN 16037.
- Labelling, transport and storage
- CLP labelling: GHS05 pictogram, Signal word “Danger”, H318 “Causes serious eye damage”.
- Not assigned a UN number at publication; not classified by manufacturers as a dangerous good under RID/ADR/IMDG/IATA at that time.
- Packaging: polyethylene bags (1–25 kg) or flexible bulk containers (≤ 1 000 kg). Store cool, dry, in plastic containers - avoid common construction metals and heat > 60 °C.
- Safety
- First aid, spillage and fire procedures described (see Annex B). Avoid mixing with alkalies, hypochlorites or metals.
Applications and Who Uses This Standard
- Primary use: pH adjustment in public and private swimming pools.
- Users and beneficiaries:
- Pool operators and facility managers ensuring safe dosing and storage.
- Chemical manufacturers and suppliers producing sodium hydrogen sulfate for pool use.
- Testing laboratories verifying conformity to purity and impurity limits.
- Regulators and procurement specialists specifying compliant pool water chemicals.
