Climate chambers DEF STAN 00-35 Pt3 CN2: Salt (corrosive) atmospheres
Lenpure Salt Spray Test Chamber could evaluate the anti-corrosion ability of materal and material coating , make a comparsion about the product techniques and quality of similar coating and products , It be used to test the electronic elements, and metal materials and industrial products.
The salt mist test consists of one conditions period of exposure in a salt mist atmosphere at an ambient temperature of 35 ±2 ℃ followed by recovery at controlled laboratory conditions.
Foe simulations of long term exposure 672 hours (28 days) is recommended.
The salt corrosion test consist of four cycles of salt mist sprayed at an ambient temperature of 15 ~35 ℃ at 93%(+2%~3%）RH in accordance with test BS EN 60068-2-52: test Kb. For simulation of long term exposure, four 7 days cycles should be used. For occasional exposure, there 24 hour cycles are recommended.
The environmental test specifications shall state:
a. Whether the test is a demonstration of corrosion resistance, functional performance or survival.
b. The test procedure to be applied.
c. The test cycle and the severity to be applied.
d. The number of test cycles to be applied.
e. If functional performance is to be assessed, the phases of the test when the specimen is to operate and be assessed and the levels of performance required.
f. Whether the specimen is to be tested packaged or unpacked.
g. Whether visual or other examinations are required, the phases of the test at which they are to be conducted and the requirements to be met.
h. The method of mounting and orientations of the specimen.
i. Any permitted deviations from the test procedure.
j. Any additional parameters to be recorded.

4 cycles each of 2 hours spraying followed by storage for 7 days at 40 ±2 ℃ and 93(+2%, -3%) RH. 3 cycles each of 2 hour spraying followed by Storag for 22 hours at 40 ±2 ℃ and 93(+2%, -3%) RH. |
The salt spray corrosion test chamber can evaluate the salt spray corrosion resistance of the material and its protective layer, and the process quality of similar protective layers. At the same time, it can evaluate the resistance of some products to salt spray corrosion. The product is suitable for parts and electronics. Salt spray corrosion test of components, protective layers of metal materials and industrial products.
The salt spray test chamber uses salt spray corrosion to detect the corrosion resistance of the tested samples. The salt spray is a dispersion system consisting of tiny droplets of salt in the atmosphere. It is a series of artificial environment three-proof series. One type, many enterprise products need to simulate the damage caused by the surrounding climate of the ocean, so the salt spray test box should be shipped.
The salt spray test is divided into two types: neutral salt spray and acid salt spray. The difference is that the standard is different from the test method. It is called "NSS" and "CASS" test respectively. It is the most common test in artificial three weather protection. method.
1. Adopting Japan imported "U-Control" brand control instrument, 7-inch high-definition true color LCD touch screen display
2. Real-time monitoring (monitor controller real-time data, signal point status, actual output status)
3. Curve recording function 3.3.1. The controller can store historical data within 600 days (in the 24-hour running state, the recording interval is more than 1min, the control data is recorded at the same time), and the historical data curve of the uploaded control can be played back.
4. In the machine stop state, you can insert the U disk to export or upload data at any time, and the exported file can be viewed or converted to EXCEL format by computer with random gift software.
5. The instrument is equipped with a USB port, which can directly preview and print the micro printer through the port (optional)
6. Control uses the same channel coordination control of P.I.D + S.S.R system
7. With automatic calculation function, the temperature and humidity change conditions can be corrected immediately, making the control more precise and stable.
Here are some ways to maintain the slat spray test chamber.
1. After each test, the oil water separator switch should be turned on, the oily water should be drained and wiped clean.
2. If the tester should not test for a long time, the water of the saturator should be drained. When using it normally, the water in the saturator should be replaced regularly.
3. When it is not used for a long time, if it is re-tested, it should be checked systematically for all electrical appliances and water supply and gas supply systems to prevent malfunction after starting up.
4. The nozzle is found to be clogged with dirt. Remove the nozzle in time, clean it with alcohol, xylene or 1:1 hydrochloric acid or carefully remove it with ultra-fine steel wire. Do not damage the nozzle wall to avoid affecting the spray quality.
