Publications referred to

Requirements for coatings before and after their application. Also specifies the pre-treatment of the aluminium alloy. (See also BS 6496).

Section 2 of BS 4842 specifies requirements for liquid organic coatings which are intended for application to aluminium alloy extrusions, sheet and preformed sections that are not to be further formed (except for cutting).

Section 3 of BS 4842 specifies requirements for the finish on aluminium alloy extrusions, sheet and preformed sections when so coated.

The methods of test for these coatings and finishes are described in section 4.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
