How does Winmate test/ verify its anti-corrosion products?
Salt spray test is a standardized test which widely used in the Marine/ industrial products to evaluate different corrosion prevention methods.
Test Equipment: Winamte’s Salt-mist test Machine – Weiss/ SC450 in National Taiwan University
Test period depends of the corrosion resistance of the coating; the more prevention of corrosion the longer the period in testing without showing appearances of corrosion.
Refer to IEC60945:2002, Section 8.12 Test sequence-1: Salt spray test, exposing for 2 Hours
At temperature 35C
Saline solution: 5% NaCl, PH 6.5 to 7.2
Quantity of fog: 1.0~ 2.0ml/80 cm2 / hour Test sequence-2: Humidity storage test, exposing for 168 Hours
Storage Temperature: 40C
Humidity in chamber during storage: 93%
Above test sequences shall perform for 4 cycles
