Coil coating products are generally tested both under accelerated and natural weathering conditions with respect to their corrosion In this paper the focuses is on the anticorrosion behaviour of press hardened galvanized steel sheet in unpainted and painted condition, based on standard cyclic corrosion tests Indentation Hardness Tester acc. This test procedure has been developed to judge the corrosion protection of vehicle VDA (ISO Cycle B)emperature °C emperature °C Humidity % RH e °C y % RHhours VDA, which is the new cyclic corrosive environment lab test developed by a working committee under the direction of voestalpine experts, has become the new Missing: pdf CCT is effective for evaluating a variety of corrosion types, including galvanic corrosion and crevice corrosion. It is claimed that testing according to this procedure can generate results that correlate well with those seen by driven vehicles VDA (VDA – Wechseltest) Salt mist, condensed water, standard climate (18°C, salt mistweek VW P VDA Salzsprühnebel°C DIN EN ISO NSSh Kondenswasser-Konstantklima°C DIN EN ISO CHh Belüftung Raumluft°C ±°C DIN EN ISO AHTh Start: Montag, h Dienstag bis Freitag Samstag Sonntag/ Montag h Lagerung im Raumklima°C ±°C DINxhx Dienstag bis Freitagx The chamber will be loaded with test samples as required by the customer or in accordance VDA (° from horizontal)A high quality device for independent control of temperature and relative humidity shall be accessible.
