Corrosion resistance
Sliding doors used to date in bathrooms have been susceptible to possible rusting, but they are now made of
stainless steel to provide drastically added corrosion resistance.
Test procedures:
CASS test (JIS H8502), 48 hrs x 3 cycles ... total 144 hrs
Mix the sodium chloride solution used in a salt spray test with slight volumes of acetic acid and copper
chloride for enhanced corrosion resistance to examine the corrosion resistance of test specimens. This
test method is mainly used to test the corrosive resistance of plated articles, such as auto parts. Being a
corrosion test carried out in an acid atmosphere, this test is more demanding than the salt spray test.
