This Standard specifies the testing method of sealing by the chromic-phosphoric solution immersion test on anodic oxidation coatings (hereafter referred to as "coatings") applied to the products manufactured from aluminium and aluminium alloys (hereafter referred to as "products").<\/p>\n
\nThis Standard includes the following two testing methods.<\/p>\n
\n– Method 1 : The method without prior acid treatment applicable to the coatings intended for decorative or protective purpose.<\/p>\n
\nFor less severe applications, this method may be suitable.<\/p>\n
\n– Method 2 : The method with prior acid treatment applicable to the coatings intended for architectural purpose or the like.<\/p>\n
\nThese methods are not applicable to the following.<\/p>\n
\na) Hard-type coatings to which sealing treatment is not applied<\/p>\n
\nb) Coatings sealed with dichromate<\/p>\n
\nc) Chromic acid coatings<\/p>\n
\nd) Coatings to which hydrophobic treatment is applied<\/p>\n
\nNOTE 1 The methods are destructive and can serve as reference methods in case of doubt or dispute regarding the results of the test for loss of absorptive power (JIS H 8683-1) or the measurement of admittance (JIS H 8683-3).<\/p>\n
