I. SCOPEI.I Scope. This specification covers the requirements for six types andtwo classes of electrolytIcally formed anodic coatings on aluminum andaluminum alloys for non-architectural applications (see 6.1).1.2 Classification. The anodic coating Types and Classes covered by thisspecification are as specified herein (see 6.2 and 6.21):Type IType IBType ICType IIType lIBType I l l- Chromlc acld anodizing, conventlonal coatings produced fromchromic acid bath (see 3.4.1)- Chromic acid anodizing, low voltage PFOCeSS, 22 + 2V,(see 3.4.1)- Non-chromic acid anodlzing, for use as a non-chromatealternatlve for Type I and IB coatings (see 3.4.1 and 6.1.2)- Sulfuric acld anodizing, conventional coatings produced fromsulfurlc acld bath (see 3.4.2)- Thin sulfuric acld anodizing, for use as a non-chromatealternatlve for Type I and IB coatings (see 3.4.2 and 6.1.2)- Hard Anodic Coatings (see 3.4.3)1.2.2 Classes.Class IClass 2- Non-dyed (see 3.5.)- Dyed (see 3.6.)Beneficial
