GENERAL INFORMATION The

14、 information given below is provided for clarification and assistance in meeting the requirements of these specifications. 5.1 SIGNIFICANT SURFACES Unless otherwise specified on the engineering drawing, significant surfaces are defined as those surfaces of the finished part that: . Are directly visi

15、ble and/or visible by reflection when the finished part is assembled in position. . Can be the source of corrosion products directly visible or visible by reflection. 5.2 HEXAVALENT CHROMIUM FREE CONVERSION COATINGS Special finishes may be required on some parts, in which case the Engineering Drawin

16、gs will be marked accordingly. Zinc/tin plate plus hexavalent chromium free treatment; or zinc/tin plate plus black finish. Example: Zinc/tin plate per WSF-M1P93-A1, Class 1 plus hexavalent chromium free coating. In barrel operations the black post treatment may vary from dark greenish black, to slight iridescent black to total black just as long as the corrosion value requirements are met.
