To obtain the Fixed Residue at 180° mg/l, the temperature of the water is increased to 180° and the residual mineral salts are examined.
This value is used in mineral water to indicate the total weight of mineral salts.
The lower the value, the lighter the mineral water is.
The higher the value, the more mineral salts with a significant weight are present.
