GENERAL INFORMATION The information given below
14、is provided for clarification and assistance in meeting the requirements of this specification. 4.1 ES REQUIREMENT Wheels to meet the requirements as specified in Wheel Engineering Specification (ES-7U5A-1007-AA). 4.2 RE-WORK Wheels to be processed through coating operations a maximum of 2 times (in
15、itial and one re-work). Re-worked wheels must match the master samples originally approved by the Design Center and meet all of the specification performance requirements. 4.3 STRIPPING Wheel stripping processes must not degrade the mechanical properties of the wheel. All wheel stripping processes must have prior approval by the responsible Material & Wheel Engineering activity.
