United States1D1540 Method of Test for Effect of Chemical Agents on Organic Finishes Used in the Transportation Industry (Withdrawn1992

12、)33. Summary of Test Method3.1 Concentrated or diluted cooling system chemical solutions are brought into contact with organic finishes typical of thoseused on automobiles for 1 h at room temperature. The surface of the finish then is inspected visually for any of the surface changesmentioned in Sec

13、tion 4.4. Significance and Use4.1 This test method will distinguish between cooling system chemical solutions that do or do not have a tendency to changethe surface appearance when applied to organic finishes used on vehicles. Such changes may be manifested by discoloration, lossof gloss, softening,

14、 swelling, or other similar phenomena.5. Materials5.1 Test PanelsSteel panels, approximately 100 by 150 mm (4 by 6 in.) shall be prepared in accordance with the Methods ofPreparation of Practice D609. The surface of the test panels shall be roughened to 0.25 to 0.50 m (10 to 20 in.) prior to applyin

15、gthe organic finish. These panels shall be coated with an organic finish of the type used on vehicles such as clear coated andnon-clear coated thermoset urethane and acrylic urethane finishes. Other finishes and painted panels of varying age and dimensions(24 in.2 minimum) may be used upon agreement

16、 between the customer and supplier.6. Test Solution6.1 The coolant to be tested shall be either a concentrate or a dilution. Sufficient ASTM Type IV water shall be added to yielda solution of 50 % concentration by volume in accordance with Test Method Practice D1176, section on Preparation of Soluti

17、onsRequiring Inclusion of Separated Solids and Liquids. Any separated solids or liquids shall be included in the test material.6.2 Other cooling system chemicals shall be tested both without dilution and at a typical use concentration as indicated byinstructions on the label. Any separated solids or

18、 liquids shall be included in the test material.7. Procedure7.1 Conduct the test at 25 6 5C5 C without humidity control.7.2 Select a test panel prepared in accordance with Section 5. Place sufficient test solution on the surface of the test panel toform spots approximately 25 mm (1 in.) in diameter.

19、7.3 After 1 h, wipe the surface with a wet cloth, buff with a soft, dry cloth and examine the finish for visual and physicalevidence of the effects listed in Section 4.7.4 Lightly polish the test surface with any well-known liquid car cleaner. Compare the untreated area with the treated spotson the

20、basis of removability of the stain.NOTE 2Stains may disappear after short exposure to the weather, for example, 8 to 24 h of sunshine. Such stains are considered by some personsto be unobjectionable.8. Report8.1 The report shall include the following:8.1.1 Product and concentration tested.8.1.2 Coat

21、ing systems employed.8.1.3 Type and appearance of the effect obtained on the test panel, as described in Section 4.8.1.4 Any change in surface effect brought about by use of a polishing agent and by sunlight.9. Precision and Bias9.1 PrecisionIt is not practicable to specify the precision of the proc

22、edure in this test method because the results are subjectiveobservations.9.2 BiasThere is no acceptable reference material suitable for determining the bias for the procedure in this test method.10.
