Standards and Quality

Among the various types of salt in existence (sea salt, rock salt, refined salt), refined salt is the most chemically pure. To meet the requirements of pool electrochlorination, it is this refined and chemically pure salt (> 99.9% NaCl) that should be used. The salt must meet the criteria of standard EN 16401 - Quality A. Compagnie des Salins du Midi et des Salines de l'Est is a member of the Federation of Pool Professionals (Fédération des Professionnels de la Piscine - FPP). The Salins group has Certi Piscine certification – ISO 9001

Salins salt pellets are compliant with standard EN16401 - Quality A

• Our pool salt meets the European standard EN 16401 - Quality A* which defines the physical and chemical purity criteria for salt electrolysis in pools. In addition to characterizing the purity of the salt (a minimum of 99.4% of NaCl for quality A), maximum concentration limits are set for certain metals such as copper, iron and manganese. These chemical species are responsible for a reduction of the lifetime of electrodes and permanent stains on pool liners.

*EN 16401 – Qualité A: Sodium chloride used with electrochlorination systems
– chemicals used for the treatment of swimming pool water

A refined salt with a sodium chloride content greater than 99.9%

• Special attention must be paid to the purity of salt used for pools and the absence of substances that may be harmful to the electrolyzer and to the various parts of the pool, such as manganese, iron or anti-caking agents.

• The term anti-caking agent refers to a flow agent used for storing table salt to prevent it clogging. Standard EN 16401– Quality A does not authorize the use of such a chemical which can also be found in some fine or coarse salts and pellets of poor quality, sold as salt for pools. When dissolved in water, this chemical releases hexacyanoferrate ions causing permanent stains on the pool and its equipment.
