A pH reading or acid content of trichloroethane vapor degreasing solution, or both, should be obtained. Last previous edition D — 90 This test depends on the observation that a clean surface one that is chemically active or polar will hold a continuous?

Abrasive and debris should be wiped awtm water rinsed from the surface. The methods may be revised or supplemented, as necessary, to include methods based on proven performance. After removing from any rinse the water-break test is commonly used. The adhesive or adhesive primer must be applied immediately after drying. Material Sulfuric acid 6. The etching time is generally 10 to 20 min. The methods may be revised or supplemented, as necessary, to include methods based on proven performance.

Surface treatment methods involving both mechanical and chemical techniques are included for aluminum alloys, stainless steel, carbon steel, titanium alloys, magnesium alloys, and copper and copper alloys. Hand sanding, rubbing with metal wool, and wire brushing are the least effective methods. Standards should be established and records kept for such tests on each lot or vat of solution.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Surface preparation for magnesium alloys which is closely associated with corrosion prevention shall involve vapor, alkaline-detergent solution, chromic acid, and sodium hydroxide acid degreasing; anodic treatment; and the use of conversion coatings and wash primers.

NOTE 9—If treating solution is astk be used for a continuous operation or reused, it should be discarded after 4 to 6 h at the temperatures in Sand blast, grit blast, or vapor hone may be used. Wash, vaporize degrease, and brush or air blasted dry oil-free air surfaces to remove all traces of the abrasives. Initial treatment is at about 5 to 10 V.

Satisfactory surface preparations have been accomplished by using paste-type etchants. Tanks should be lined with suitable materials to resist the solutions, and methods for circulating the solutions and heating with temperature controls should be included if required.

The surface will exhibit a grey or lighter color. The values given in parentheses are for information only. Apply the adhesive immediately after the treatment. Bond as soon as possible, but at least within the same working day. Longer dwell times should be satm. Do not allow to dry. The major problem is to apply sufficient thickness of coating to prevent corrosion, but not so thick that the bond fails within the coating. asfm

Full-scale property tests should be run with the metal surfaces so prepared with the adhesive in question before accepting the process. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The surface should be recleaned until the test is passed. Commercial vapor degreasing equipment is usually used. If continuous failures occur, the treating process itself should be analyzed to determine the cause of the problem.

ICS Number Code D265 acid-ferric chloride solution degreasing; sulfuric acid-dichromate-ferric sulfate solution etching; and chemical treatment by nitric-acid-sodium chlorite solutions may be used for copper and copper alloy preparation. Trial bonding followed by testing and evaluation against mechanical strength standards should be conducted to determine initial and continuous effectiveness of a method.
