Changes

Single components corrosive test atmospheres and testing with two gas exposures following each other provide only limited validity. Flowing gas test

atmospheres with four components have proven to be the most likely ones to realistically simulate long term natural corrosive gas exposure <xr id="tab:Typical Corrosive Gas Concentrations (ppm) Near Industrial Facilities"/><!--(Tab. 13.4)-->.
