8、sistance to Corroslon of Automotive Components by Salt Spray Fog Testing 1. Scope The object of this test method is to determine the resistance to corrosion of aluminum radiators. The test shall be conducted on complete components and examination shall be made by a subsequently performed leak test.
9、2. Definition 2.1 This fog spray test is an accelerated corrosion test and is carried out using as corrosive medium a cyclical sprayed aqueous solution of sodium chloride and acetic acid. Compressed air is used to spray the solution. 2.2 The method is known as the SWAAT test. SWAAT being an abbrevia
10、tion for “sea water acetic acid test“. 3. Test Pieces Tests shall be conducted on complete components. 4. Test Apparatus 4.1 The apparatus required for this test consists of a fog chamber, a salt solution reservoir, a supply of suitably conditioned compressed air, one or more atomizing nozzles, spec
11、imen supports, provisions for heating the chamber, and necessary means of control. The size and detailed construction of the apparatus are optional, provided the conditions obtained meet the requirements of this method. Suitable apparatus that may be used to obtain these conditions are indicated and
12、 described in GME 60206. 4.2 Suitable compressed air source and pressure gauge for 150 kPa overpressure, accuracy 10 kPa. 5. Test Solution The test solution shall be prepared by dissolving reagent grade salt (sodium chloride NaCl to DAB7) in dis-tilled or deionized water and additional of acetic aci
13、d (analytical grade or DAB7). The test solution shall con-sist of 42 g of salt and 10 ml of water free acetic acid per litre of solution. The pH of the test solution shall then be adjusted, by the addition of caustic soda solution (sodium hydroxyd NaOH, analytical grade or DAB7), so that the spray s
14、olution and collected condensate have a pH between 2.8 and 3.0. The pH mea-surements shall be made electrometrically at (+25 2) C using a glass electrode.
