Specifications include, but are not limited to: 2.1.1 Magnesium Chloride, % 29 minimum 2.1.2 Total Phosphates, ppm 25 maximum 2.1.3 Cyanide, ppm 0.20 maximum 2.1.4 Chromium, ppm 0.5 maximum 2.1.5 Cadmium, ppm 0.15 maximum 2.1.6 Calcium, ppm 100 maximum 2.1.7 Sulfate, % 0.8 maximum 2.1.8 pH 6-9* *Exception to pH requirements: Recent testing has concluded that brines inhibited with organic matter that generate weak organic acids may exhibit lower pH values. Corrosion testing has indicated the weak organic acids enhance the corrosion inhibiting power of the products. Due to this, the pH requirement on materials that contain organic matter may be waived. Suppliers must apply for the waiver and provide information as to what the organic matter is and it's concentration in the product. The Department reserves the right to use any and all tests to verify the supplier data.
