Corrosion Resistance of Coating Electronics Neutral Salt Spray Testing Chamber
SO2 Salt Spray Test (cyclic) can be used to test the relative resistance to corrosion of product samples that are likely to encounter a combined SO2(sulfur dioxide)/salt spray/acid rain environment during their usual service life. Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles. In either case, the exposure to salt spray may be salt water spray or synthetic sea water prepared in accordance with the requirements of the test standard. The most appropriate test cycle and spray solutions are to be agreed between parties.
The first climate cycle comprises a continuous indirect spray of neutral (pH 6.5 to 7.2) salt water/synthetic seawater solution, which falls-out on to the specimens at a rate of 1.0 to 2.0ml/80 cm²/hour. During this spraying, the chamber is dosed with SO2 gas at a rate of 35 cm³/minute/m³ of chamber volume, for 1 hour in every 6 hours of spraying. The entire test cycle is at a constant chamber temperature of +35C. The number of cycle repeats and therefore the test duration is variable.
The second climate cycle comprises 0.5 hours of continuous indirect spray of neutral (pH 6.5 to 7.2) salt water/synthetic seawater solution, which falls-out on to the specimens at a rate of 1.0 to 2.0ml/80 cm²/hour. This is followed by 0.5 hours of dosing with SO2 gas at a rate of 35 cm³/minute/m³ of chamber volume. This is followed by 2.0 hours of high humidity soak. The entire test cycle is at a constant chamber temperature of +35C. The number of cycle repeats and therefore the test duration is variable.
1, Chamber material is made of P.V.C Sheet, sturdily and will not be out of shape.
2, Test chamber is heated from five directions to ensure the temperature is uniformity distributed.
3, Spray nozzle is specially made, enable to spray the salt water with considerable speed, then falls on the surface of samples.
4, Hot and moist air keeps the humidity in the test chamber conforms testing request.
5, High precision P.I.D. temperature controller limits the temperature difference within the range of ±0.1℃.
Please Note Small Type of 60 and 90 do not meet standard of ASTM B117.
