PP board salt spray test chamber

The PP board salt spray test chamber is mainly designed for adaptability testing of electrical and electronic products, their raw components, as well as various metal materials and their protective layers during storage, transportation, and use in salt spray, damp heat, and dry environments.

pp boardSalt Spray Test Chambermatters needing attention:

1.The salt solution is prepared using sodium chloride (chemically pure, analytical pure) and distilled or deionized water,

Its concentration is（5±0.1）%The collected liquid after atomization, except for the blocking part of the baffle, must not be heavy

Reuse.

2.Salt solution before atomizationpHValue in6.5~7.2（35±2℃）When preparing salt solutions, chemically pure dilute hydrochloric acid or sodium hydroxide solutions can be used to adjustpHValue, but concentration still needs to meet（5±0.1）℅.

PP board salt spray test chamber test method.
1.Conduct visual inspection on the test samples and perform electrical and mechanical performance testing in accordance with relevant specifications

2.Salt spray should fill all exposed spaces inside the salt spray box, with a horizontal collection area of80cA clean collector of square meters is placed at any point in the space, averaging every hour during each collection cycle1.0mL~2.0mLThe solution. Less than two collectors should be used. The collectors should be placed in a location that is not covered by the test sample and avoid condensation from all directions entering the collectors.

3.salt spray

-Spray temperature:15℃~35℃Test duration: 2Hr

4.Constant temperature and humidity storage

-temperature: 40℃±2℃;

-relative humidity: 93-3%/+2%;Test duration:20Hr~22Hr

5.Repeated brine spray and constant temperature and humidity storage for 4 times

6.Standard pressure storage

-Temperature: 23 ℃± 2 ℃;

-Relative humidity: 45%~55% Test duration: Three days

7.Cleaning and storage

-Rinse with running water for 5 minutes, then rinse with distilled water to remove water droplets. Dry at 55 ℃± 2 ℃ for 1 hour and cool for 1-2 hours

8.The test samples should undergo appearance and characteristic tests as specified in relevant standards and regulations
