18、mum average value of three samples will be 30 lb/inch of width. 4.2.2.2 Bend Test A one-inch strip bent 180 flat with the stainless steel face on the outside will show no delamination after being straightened (returned) to a flat condition. 4.2.3 Corrosion Resistance 4.2.3.1 CASS Test There shall be
19、 no corrosion sites on the surface of the stainless steel face after 16 hours of CASS testing per ASTM B 368. Corrosion sites are identified by rust discoloration (“run-down”) or pitting. Corrosion from the sheared edges will be discounted. 4.2.3.2 Ferric Chloride Spot Test There shall be no pitting
20、 or etching visible to the unaided eye when viewed perpendicular to the surface after a 5-minute exposure to the following acid spot test. 4.2.3.2.1 Apply a single drop of acid solution to the cleaned stainless steel face of the clad material using a clean eyedropper. After five minutes, remove the
21、acid drop by rinsing in water and wiping with a soft cloth or paper towel. 4.2.3.2.2 The acid solution is prepared by dissolving 10g of ferric chloride (FeCl3 .6H20) and 5g sodium chloride (NaCl) and 2.5 ml of hydrochloric acid (HCl-concentrated) in 200 ml of distilled water. 4.3 Finish Requirements
