Zinc-Nickel plating is one of the best corrosion resistant finishes available offering over 5 times the protection of conventional zinc plating and up to 1, 500 hours of Neutral Salt Spray test performance.

The use of neutral salt spray, in accordance with the ASTM B 117 specification, for the measurement of corrosion performance is well documented in the literature and is still the most widely accepted method for coating evaluation.

Isaac knows what Carter was up to when he gave a patient " 60 drops of Spiritus Minderius to act as a neutral salt to remove obstructions that such a viscid blood must occasion, " and he explains it.

The most common test for steel based materials is the Neutral Salt Spray test ( often abbreviated to NSS ) which reflects the fact that this type of test solution is prepared to a neutral pH of 6.5 to 7.2.

Salts that hydrolyze to produce hydroxide ions when dissolved in water are alkali salts, whilst those that hydrolyze to produce hydronium ions in water are " acidic salts " . " Neutral salts " are those that are neither acid nor basic salts.

Gypsum also reacts with sodium carbonate to convert into sodium sulphate which is a neutral salt and does not contribute to high pH . There must be enough natural drainage to the underground, or else an artificial subsurface drainage system must be present, to permit leaching of the excess sodium by percolation of rain and / or irrigation water through the soil profile.
