BS EN 896 is a European standard that gives information on sodium hydroxide for use in the treatment of water intended for human consumption.
BS EN 896 is applicable to sodium hydroxide used for the treatment of water intended for human consumption. BS EN 896 describes the characteristics and specifies the requirements and the corresponding test methods for sodium hydroxide. BS EN 896 gives information on its use in water treatment. BS EN 896 also determines the rules relating to safe handling and use.
BS EN 896 on water intended for human consumption - sodium hydroxide is useful for:
Sodium hydroxide is used in the treatment of drinking water to raise the pH of the water to a level that minimizes corrosion. Raising pH remains one of the most effective methods for reducing lead corrosion and minimizing lead levels in drinking water.
Too much use of sodium hydroxide in water treatment would be dangerous for the health that can cause severe burns to the eyes, skin, digestive system, or lungs, resulting in permanent damage or death. Therefore, BS EN 896 provides the rules relating to safe handling storage, and the use of sodium hydroxide in the treatment of water intended for human consumption.
BS EN 896 provides you with the minimum purity requirements for sodium hydroxide used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities.
BS EN 896 provides you guidance on test methods that include sampling and analysis. BS EN 896 guides the labelling, transportation, and storage of the product so that the purity is not affected. BS EN 896 helps to avoid potential adverse effects on the quality of water intended for human consumption.
