Corrosion of metals and alloys. Method for determination of the uniform corrosion rate of stainless steels and nickel based alloys in liquids
金属和合金的腐蚀 不锈钢和镍基合金在液体中均匀腐蚀速率的测定方法
BS ISO 18069:2015 specifies the measurements of the corrosion rate of uniform corrosion
for stainless steels and nickel based alloys in the intended liquids and the ability for the material to
passivate after activation.This method is intended to be used for estimation of the uniform corrosion rate in liquids, under
atmospheric conditions, for the chemical industry under specific environmental conditions and not as a
qualification test. It can also be used to determine iso-corrosion diagrams and at which temperature the
corrosion rate exceeds 0,1 mm/a.This International Standard is not intended for excessive corrosion rates above 1 mm/a since an even
higher corrosion rate indicates that the stainless steel is not suitable in the application.This International Standard is not intended to be used for solutions containing halides, especially
chlorides, since these might cause localized corrosion.Cross References:ISO 3696ISO 8044ISO 17864ISO 6344-3All current amendments available at time of purchase are included with the purchase of this document.
