1.1 These test methods cover a procedure for evaluating the ability of sintered PM stainless steel parts/specimens to resist corrosion when immersed in a sodium chloride (NaCl) solu-tion.
1.2 Corrosion resistance is evaluated by one of two meth-ods. In Method 1, the stainless steel parts/specimens are examined periodically and the time to the first appearance of staining or rust is used to indicate the end point. In Method 2,continued exposure to the sodium chloride solution is used to monitor the extent of corrosion as a function of time.
