If no Ford or industry standard exists to describe the material, the name of the material supplier and their trade name / product code shall be listed. Additional material information (see note in 3.1.1.1) should
14、also be included. Generic terms such as: “steel“, “oil“, “plastic“ or “rubber“ are not acceptable. 3.2.2 GRAY BOX COMPONENTS, MATERIAL IDENTIFICATION 3.2.2.1 For single component drawings, the material, finish, and additional material information shall be included on the drawing. 3.2.2.2 For assembl
15、y and sub-assembly drawings, this standard and Standard A-3, para. 3.1.3.6.1 requires the material, finish, heat treatment, and material codes be listed for each component in the bill of material.
