G85-A2可程式复合盐雾试验箱满足G85–09Standard Practice for Modified Salt Spray (Fog) Testing中A2测试标准，实现盐雾、强制干燥、高湿三个过程的交替循环测试！
可程式复合盐雾试验是一种综合性盐雾试验，将产品在盐雾、强制干燥、湿热三种环境条件下交替转换，来考核整机产品的电性能和机械性能有无变化。
G85-A2复合盐雾试验箱的测试条件：
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.
