Organization: ASTM International
Publication Date: 1 April 2011
Status: inactive
Page Count: 4
ICS Code (Enamels): 25.220.50
significance And Use:

It is difficult to overemphasize the importance of the spall test. Porcelain enameled aluminum that fails this test will probably spall in service if subjected to moisture or weathering.

scope:

1.1 These test methods cover accelerated determination of the resistance of porcelain enamel coatings on aluminum alloys to spalling from exposure to moisture or weathering. Test Method A, using a 5 % solution of ammonium chloride, requires 96-h immersion while Test Method B, using a 1 % solution of antimony trichloride, is completed after 20 h of immersion. The spalling tendency is evaluated by the same criteria in both methods. While either method is suitable for magnesium silicon alloys, such as 6061, Test Method B is preferred for simple alloys or commercially pure aluminum, such as 1100.
