6、Testing PurposesD1540 Method of Test for Effect of Chemical Agents onOrganic Finishes Used in the Transportation Industry(Withdrawn 1992)33.Summary of Test Method3.1 Concentrated or diluted cooling system chemical solu-tions are brought into contact with organic finishes typical ofthose used on auto
7、mobiles 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 cooling sys-tem chemical solutions that do or do not have a tendency tochange the surface a
8、ppearance 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,approximately 100 by 150mm(4 by 6 in.)shall be prepared in accordance with theMethods of Prepara
9、tion of Practice D609.The surface of thetest panels shall be roughened to 0.25 to 0.50 m(10 to 20 in.)prior to applying the organic finish.These panels shall becoated with an organic finish of the type used on vehicles suchas clear coated and non-clear coated thermoset urethane andacrylic urethane f
10、inishes.Other finishes may be used uponagreement between the customer and supplier.6.Test Solution6.1 The coolant to be tested shall be either a concentrate ora dilution.Sufficient ASTM Type IV water shall be added toyield a solution of 50%concentration by volume in accor-dance with Test Method D117
