What is BS EN 12126 - Water intended for human consumption - Liquefied ammonia about?
BS EN 12126 is a European standard that discusses rules relating to the safe handling and use of liquefied ammonia in the treatment of water intended for human consumption.
BS EN 12126 is applicable to liquefied ammonia used for the treatment of water intended for human consumption. BS EN 12126 describes the characteristics and specifies the requirements of liquefied ammonia and refers to the corresponding analytical methods. BS EN 12126 gives information about its use in water treatment. BS EN 12126 also determines the rules relating to the safe handling and use of liquefied ammonia.
Who is BS EN 12126 - Water intended for human consumption - Liquefied ammonia for?
BS EN 12126 on water intended for human consumption - liquefied ammonia is useful for:
- Water treatment plant
- Chemical laboratories
- Health and safety bodies  
- Regulatory authorities 
- Chemical industries 
- Water suppliers
Why should you use BS EN 12126 - Water intended for human consumption - Liquefied ammonia?
Liquefied ammonia has been a common drinking water treatment in municipal treatment facilities for more than seven decades. The disinfection properties of chlorine are boosted when liquefied ammonia is added to the water, which is why this combination of chemical compounds is used to disinfect contaminated water.
Liquefied ammonia’s excessive use would be dangerous to health, which can cause corrosive injury including skin burns, permanent eye damage, or blindness. Therefore, BS EN 12126 provides the rules relating to the safe handling and use of liquefied ammonia.
BS EN 12126 provides you with the minimum purity requirements for liquefied ammonia 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 12126 provides you guidance on test methods that include sampling and analysis. BS EN 12126 guides the labelling, transportation, and storage of the product so that the purity is not affected. BS EN 12126 helps to avoid potential adverse effects on the quality of water intended for human consumption.
What is changed since the last update?
