The salt spray test:
In cooperation with the Technical University of Esslingen, a total of 9 products from 6 different manufacturers were subjected to quality testing in December of 2002 in the form of a salt spray durability test in accordance with DIN 50021 SS. The object of this testing was to compare corrosion resistance of the various systems under consideration of environmental influences such as salt water. During the test simulation of over 480 hours, the samples were inspected at regular intervals, whereby the corrosion resistance of piston rods and threaded struts were evaluated, as well as the adjustability of the aluminum spring collars.
Participants/Products:
KW „Inox-line“ Coilovers Variant 1, 2 and 3
KW Coilover struts Variant 2
5 competitor products with new, galvanized threaded struts
Evaluation:
2x very good KW „inox-line“ Variant 1 and Variant 3
1x good KW „inox-line“ Variant 2;
2x moderately good competitor
1x moderate competitor
2x poor competitor
Test Result FH Esslingen:
KW inox-line coilovers with stainless steel technology are clearly superior to galvanized models with regard to corrosion resistance, and in addition, ensure smooth operation even after 480 hours.
