Accelerated Weathering FAQs |Q-Lab

Obviously, it is logically meaningless to talk about a conversion factor between hours of accelerated weathering and months of outdoor exposure. One is a constant condition, whereas the other is variable. Looking for a conversion factor requires pushing the data beyond the limits of its validity. In other words Weathering data is comparative data.An in situ investigation of the corrosion behaviour of a weathering steel accelerationAn in situ investigation of the corrosion behaviour of a weathering steel work of art weathering steel acceleration Polymeric electrodes were employed instead of the traditional electrochemical cell to avoid any acceleration of the corrosion process; the applied stimulus was in the range 0.001 Hz100 kHz, while the measurement range could span from about 100 to 1 G weathering steel accelerationAtmospheric corrosion resistance of MnCuP weathering steel weathering steel accelerationDec 01, 2011In this work, atmospheric corrosion resistance of low cost MnCuP weathering steel in simulated coastal, industrial, and coastalindustrial atmospheric environments was investigated by wet/dry cyclic acceleration corrosion tests. The results indicate that MnCuP weathering steel exhibits high corrosion resistance in the three atmospheres.
