Anodizing of aluminium and its alloys. Experimental research on possible alternative sealing quality test methods to replace the phosphoric acid/chromic acid immersion test. Evaluation of correlations Ingestion-build-67170 93/95 Ohm) are also covered1 Scope This Technical Report contains data from an evaluation of candidates to replace the chromic phosphoric acid solution (CPA) test for the quality of sealing of anodic oxidation coatings on aluminium. Following a review by Qualanod (see Working Group report in Annex A), it was agreed with Sapa Technology that the candidate tests for evaluation would be as follows: acetic acid sodium acetate solution (AASA) test as described in ISO 2932[10], a
