Overview
The draft European Standard oSIST prEN 15076:2020:2020, developed by CEN/TC 164, sets forth specifications for sodium hydroxide solutions used in the treatment of swimming pool water. It updates and supersedes the previous EN 15076:2013 standard, providing detailed requirements on the characteristics, purity, test methods, labelling, transportation, and storage of sodium hydroxide products. This standard serves as a crucial reference to ensure safe, effective, and consistent use of sodium hydroxide, also known as caustic soda, in maintaining pool water quality.
Sodium hydroxide is widely used in swimming pool water treatment as an alkaline agent to control pH levels, ensuring safe and comfortable water conditions. oSIST prEN 15076:2020 defines the properties and purity limits needed for this chemical to be fit for purpose while complying with relevant European regulations on chemical safety.
Key Topics
Scope and Application
The standard covers sodium hydroxide in solid (flakes, pearls) and aqueous solutions, either for direct use or as intermediates in pool water treatment formulations. Concentrations typically vary with mass fractions of 30% to 50% in liquid form, or solid products with minimum purity of 96% NaOH.Chemical and Physical Properties
Detailed parameters such as appearance, density, solubility, vapor pressure, boiling point, crystallization temperature, specific heat, and viscosity are specified to characterize sodium hydroxide products accurately.Purity Criteria and Impurities
The standard outlines maximum permissible limits for key impurities including sodium chloride (max 2.4%), sodium carbonate (max 0.4%), and sodium chlorate (max 0.7%) to avoid compromising water treatment effectiveness or causing equipment damage. Trace heavy metals like arsenic, cadmium, mercury, nickel, and lead are also regulated with strict upper thresholds to ensure chemical safety.Test Methods
Standardized analytical methods for sampling and testing are referenced from EN 896, ensuring reproducible and accurate verification of sodium hydroxide purity and composition.Labelling and Transportation
Compliance with EU chemical classification and labelling (CLP Regulation) is mandated, including hazard statements for skin and eye irritation (H314). Transportation follows UN 1824 and specific rules under RID/ADR, IMDG, and IATA regulations, emphasizing the need to recognize chemical incompatibilities during transport.Storage Guidelines
Recommended materials for containers include mild steel with suitable linings, polyester, or polypropylene. Avoid contact with metals like aluminum, zinc, or copper to prevent hazardous reactions. Proper storage avoids contamination from carbon dioxide absorption, which forms sodium carbonate.
Applications
Sodium hydroxide as regulated by oSIST prEN 15076:2020:2020 is primarily used in:
Swimming Pool Water Treatment
Adjusting and maintaining optimal pH to prevent corrosion, scaling, and microbial growth, enhancing swimmer safety and water clarity.Formulation of Pool Chemicals
Acting as a key ingredient in compound formulations for disinfection and water conditioning within commercial and residential pool maintenance products.Industrial and Municipal Water Treatment Contexts
While focused on pools, the high-purity sodium hydroxide specified can also be applicable in other controlled water treatment applications requiring stringent chemical standards.
This standard supports manufacturers, water treatment specialists, pool operators, and regulatory authorities by providing a harmonized framework to source, handle, and apply sodium hydroxide safely and effectively.
Related Standards
EN 896 – Chemicals used for treatment of water intended for human consumption – Sodium hydroxide: referenced for test methods ensuring alignment in purity and safety evaluations.
EU Regulation (EU) No 528/2012 – Biocidal products regulation that sodium hydroxide complies with when used as a biocide in water treatment.
CLP Regulation (EC) No 1272/2008 – Classification, Labelling and Packaging requirements for hazardous substances including sodium hydroxide.
Transport Regulations
- RID/ADR (rail and road transport of dangerous goods)
- IMDG Code (International Maritime Dangerous Goods)
- IATA Dangerous Goods Regulations for air transport.
By referencing oSIST prEN 15076:2020:2020 and associated standards, stakeholders ensure compliance with chemical safety, environmental protection, and public health directives concerning swimming pool water treatment.
