Yuantai Derun zinc aluminum magnesium square tube VS traditional square tube salt spray test NSS anti-corrosion performance comparison
A neutral salt spray test, an acetic acid salt spray test, a copper salt accelerated acetic acid salt spray test, and an alternating salt spray test are all included in the artificially simulated salt spray test.
Since its introduction, the neutral salt spray test (NSS test) has been a popular accelerated corrosion test technique. As a solution for spraying, it employs a 5% sodium chloride saline solution with an adjusted pH value in the neutral range (6-7). The test temperature is 35°C, and between 1 and 2ml/80cm2.h. of salt mist must settle out per hour.
