ASTM B117 - Sunbelt Coating QA Lab, Cleveland, TN Salt fog testing is performed by placing samples in a test cabinet that has been designed in accordance with Paragraph 4 (Apparatus) of ASTM B117 and operated in accordance with Paragraph 10 (Conditions) of ASTM B117. A 5% salt solution, prepared by dissolving sodium chloride into water that meets the requirements of ASTM D1193 Specification for Reagent Water, Type IV is supplied to the chamber. At the time the samples are placed into test, the cabinet should be pre-conditioned to the operating temperature of 35ºC and fogging a 5% salt solution at the specified rate. The fog collection rate is determined by placing a minimum of two 80 sq. cm. funnels inserted into measuring cylinders graduated in ml. inside the chamber. One collection device is located nearest the nozzle and one in the farthest corner.

In this test, the coating was pierced at the top left corner. This allowed seawater to accumulate inside the coating. |

The hurricane tie on the left was coated with Storm Greeter. It was in the chamber for... 3,280 hours. During that time, seawater was allowed to accumulate inside the coating. As you can see, even though this tie was exposed for more than 3 times as long as the uncoated tie, the coating delayed the effects of the rust and corrosion. |

The hurricane tie on the right was uncoated. It was in the chamber for 1,080 hours. |
| Even on its worst day - a 2,200 hour long day, at that - Storm Greeter outperforms the industry standard! |
