GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of these specifications. 4.1 SIGNIFICANT SURFACES Unless otherwise specified on the engineering drawing, significant surfaces

13、are defined as those surfaces of the finished part that: Are directly visible and/or visible by reflection when the finished part is assembled in car position.
