    可程式復合鹽霧試驗箱

    G85-A2可程式復合鹽霧試驗箱滿足G85–09Standard Practice for Modified Salt Spray (Fog) Testing中A2測試標準,實現鹽霧、強制干燥、高濕三個過程的交替循環測試!

    可程式復合鹽霧試驗箱圖片

    可程式復合鹽霧試驗是一種綜合性鹽霧試驗,將產品在鹽霧、強制干燥、濕熱三種環境條件下交替轉換,來考核整機產品的電性能和機械性能有無變化。

    G85-A2復合鹽霧試驗箱的測試條件:

    A3.1 Salt Solution:
    A3.1.1 Use a synthetic sea salt solution made in accordance with 6.2 with the addition of 10 mL of glacial acetic acid perlitre of solution.
    A3.1.2 Adjust the pH of the salt solution between 2.8 and 3.0.
    A3.2 Conditions in Saturator Tower—Make sure the tem-perature in the saturator tower (bubble tower) is 47 6 1°C(1176 2°F) if cabinet temperature is 35°C (95°F); and 57 61°C (135 6 2°F) if cabinet temperature is 49°C (120°F).
    A3.3 Conditions in Salt Spray Chamber:
    A3.3.1 Temperature—The temperature in the exposure zoneof the salt spray chamber may vary to suit the material beingtested. The specifications that cover the material or productbeing tested define the temperature or the temperature may bemutually agreed upon between the purchaser and the seller. See Note A3.1 for recommended exposure zone temperatures forsome materials.
    NOTE A3.1—This test is particularly applicable to production control ofexfoliation-resistant heat treatments for the 2000, 5000, and 7000-seriesaluminum alloys. 4 It is also applicable to developmental studies of varyingheat treatment parameters to determine effect on corrosion behavior. Forthis purpose, a temperature of 49°C (120°F) is recommended for theexposure zone. For testing organic coatings on various metallic substrates,an exposure zone temperature of 24 to 35°C (75 to 95°F) may be used since temperatures in excess of 35°C frequently result in paint blistering.
    A3.3.2 Humidity—Although the humidity limits for opti-mum test conditions have not been determined, results of aninterlaboratory testing program indicate that it is necessary to operate under wet bottom conditions (that is, an inch or so of water should always be present in the bottom of the box). This ensures that the interior of the box does not become dry, a condition that will decrease the corrosion rate.
    A3.3.3 Cabinet—Equip the cabinet with a timing device that can be used for the following cycle: 30-min spray followed by 90-min soak at above 98 % relative humidity.
