8、mical solu-tions are brought into contact with organic finishes typical ofthose used on automobiles for 1 h at room temperature.Thesurface of the finish then is inspected visually for any of thesurface changes mentioned in Section 4.4.Significance and Use4.1 This test method will distinguish between
9、 cooling sys-tem chemical solutions that do or do not have a tendency tochange the surface appearance when applied to organic finishesused on vehicles.Such changes may be manifested bydiscoloration,loss of gloss,softening,swelling,or other similarphenomena.5.Materials5.1 Test PanelsSteel panels,appr
