ASTM C703-72-Reapproved1999

Historical Standard: Standard Test Methods for Spalling Resistance of Porcelain Enameled Aluminum

ASTM C703

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. Method A, using a 5% solution of ammonium chloride, requires 96-h immersion while 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, Method B is preferred for simple alloys or commercially pure aluminum, such as 1100.

1.2 The methods appear in the following order:

Sections Method A—Ammonium Chloride 4 to 9 Method B—Antimony Trichloride 10 to 15
