Overview

The oSIST prEN 15078:2020 standard, developed by CEN (European Committee for Standardization), specifies the requirements, characteristics, and test methods for sulfuric acid used in the treatment of swimming pool water. This standard applies to sulfuric acid used either directly or as a component in formulations for water treatment in swimming pools. It ensures safe handling, quality, purity, and effectiveness of sulfuric acid products for pool water applications.

This standard updates EN 15078:2013, providing revised guidance on product labeling, transportation, storage, and safety measures. Conformance with oSIST prEN 15078:2020 contributes to maintaining water quality in pools by controlling pH levels through safe and standardized sulfuric acid use.

Key Topics

  • Scope and Application
    oSIST prEN 15078:2020 covers sulfuric acid used for swimming pool water treatment, detailing physical and chemical properties relevant to effective pool water maintenance.

  • Chemical Identification
    Sulfuric acid (CAS No. 7664-93-9) is a strong mineral acid with the empirical formula H₂SO₄. It appears as a colorless, clear to slightly turbid liquid and is available in various concentrations, commonly between 25% and 98% mass fraction.

  • Physical and Chemical Properties
    Key properties include:

    • Density ranges depending on concentration (e.g., 1.84 g/ml at 96% mass fraction)
    • High solubility in water at all concentrations
    • Boiling point varies with concentration (up to +310°C at 96%)
    • Exothermic reaction on dilution requiring careful handling
    • Strong oxidizing and dehydrating agent with reactivity towards metals and organic materials
  • Purity and Composition Requirements
    The standard specifies limits for impurities, including sulfur dioxide, iron, arsenic, cadmium, chromium, mercury, nickel, lead, antimony, and selenium, ensuring product suitability for water treatment. Concentrated sulfuric acid must have a declared mass fraction within ±1%.

  • Safety and Handling
    Detailed safety guidelines cover labeling, delivery, transportation (classified under UN 1830 for >51% concentration), and storage precautions. Special attention is given to avoiding contact with incompatible substances such as alkalis, organic materials, and moisture.

Applications

  • Swimming Pool Water Treatment
    Sulfuric acid is primarily used to adjust pH levels in swimming pools, maintaining water balance and safety for swimmers. It helps neutralize alkaline conditions, preventing scaling, corrosion, and microbial growth.

  • Formulation of Treatment Chemicals
    Beyond direct application, sulfuric acid serves as a critical raw material in producing formulations designed for pool water treatment.

  • Industrial Water Treatment
    Although focused on swimming pools, the standard aligns with requirements relevant for certain industrial water purposes (ICS 13.060.25).

Related Standards

  • EN 899: Chemicals used for treatment of water intended for human consumption - Sulfuric acid
    Provides complementary test methods and guidelines relevant to potable water applications.

  • International Safety and Transportation Regulations
    The standard references compliance with regulations such as RID/ADR, IMDG, and IATA for safe transport of hazardous substances.

  • EU Classification, Labeling, and Packaging (CLP) Regulation
    oSIST prEN 15078:2020 aligns with EU hazard pictograms (GHS 05) and hazard statements (H314), ensuring compliance with chemical safety laws.

Practical Value

Adhering to oSIST prEN 15078:2020 ensures that sulfuric acid used in swimming pool water treatment:

  • Meets minimum purity thresholds to avoid contamination and adverse effects on water quality
  • Complies with EU safety and hygiene regulations
  • Is handled, stored, and transported with proper safety protocols to minimize risks
  • Provides reliable efficacy in controlling pool water pH and maintaining swimmer safety

By standardizing sulfuric acid specifications and use, oSIST prEN 15078:2020 supports public health, regulatory compliance, and operational safety within swimming pool water treatment industries.
