CORROSION REQUIREMENTS - SYSTEMS AND COMPONENTS

1.0 GENERAL

1.1 Purpose

This standard describes corrosion-related functional and appearance objectives for systems and components, which were agreed to by the Product Quality Committee at the meeting of August 26, 2002. It also describes the corrosion test requirements for engineering development (ED), design verification (DV), product validation (PV), and continuing conformance (CC) testing.

1.2 Coverage of this Standard

This standard applies to vehicles and service parts built by the Chrysler Group of DaimlerChrysler Corporation (DCC). It may be referenced within other system standards or performance standards. The requirements of this standard are in addition to those contained within any applicable material or process standards.

1.3 Limitations on Usage

This standard may be applied by copying the appropriate performance requirements given in Section 3.0 and the test requirements given in Section 5.0 of this standard into to the following engineering documents:

- Pre-source package

- CATIA model or Performance standard (PF)

- Design Verification Plan & Report (DVP&R)

- Product Assurance Plan (PAP)

This standard may be released directly on a CATIA model if no PF exists, or if the PF cannot be revised to include these requirements in time to meet program requirements.

2.0 CORROSION PERFORMANCE REQUIREMENTS

2.1 Appearance Requirements

Appearance requirements are defined in terms of a maximum allowable corrosion rating after a given length of service. The definition of the corrosion rating system appears in section 5.0 of this standard. 2.1.1 Class I Surface Appearance

Definition:

Class I appearance items are defined as exterior surface items that are readily visible to the customer without opening any closure panels, except as defined in paragraph 2.1.4, or that are in plain view within the vehicle interior.

Requirements:

- 1 year in service with a corrosion rating of 0, and

- 5 years in service with a maximum allowable corrosion rating of 1.

2.1.2 Class II Surface Appearance.

Definition:

Class II appearance items are defined as those items that are visible upon opening closure panels, e.g. - Door jambs and hardware,

- Liftgate or decklid drain troughs, or truck tailgate surrounds,

- Fuel filler door opening.

Class II appearance items also includes interior items that are not in plain view, but are commonly visible to the customer in the course of normal ownership and maintenance activities.

Requirements:

- 1 year in service with a maximum allowable corrosion rating of 1, and

- 5 years in service with a maximum allowable corrosion rating of 2.

2.1.3 Underhood Appearance.

Definition:

Underhood appearance items are defined as those underhood items that are readily visible to the customer in the course of normal ownership and maintenance activities.

Requirements:

- 1 year in service with a maximum allowable corrosion rating of 1, and

- 5 years in service with a maximum allowable corrosion rating of 2.

2.1.4 Underbody Appearance.

Definition:

Those underbody items that are readily visible to the customer when viewed from outside of the vehicle, with the vehicle on the ground (i.e. not on a hoist or lift), with the eye at a distance of not more than 5 meters and at a height of not less than 1 meter from the ground shall be subject to this requirement. Consideration shall be given to the position of the front wheels when assessing the visibility of chassis components, with regard for the showroom appearance of those items that may be visible with the wheels turned.

Requirement;

- 1 year in service with a maximum allowable corrosion rating of 1, and

- 5 years in service with a maximum allowable corrosion rating of 2 only for those items that are in plain view directly through the face of the wheels, except brake rotors;.

2.2 Functional Requirements

Definition:

Functional requirements are defined as those physical, electrical, or mechanical attributes that describe the function of an item, e.g., structure, output, or serviceability. Design life is defined as the required period of time that the item must retain its functional requirements. This may be less than the life of the vehicle if it is intended that the part be serviced or replaced. The responsible engineering department shall define the functional requirements and design life of the item under test.
