Stellantis PF.90152 Wheel Covers and Fender Covers - Performance Standard

The “Stellantis PF.90152 Wheel Covers and Fender Caps - Performance Standard”, developed by Stellantis, a multinational automotive manufacturing company formed by the merger of Italian-American Fiat Chrysler Automobiles (FCA) and the French PSA Group, describes the environmental, physical, electrical, mechanical, functional, regulatory, and durability requirements for wheel inner linings and fender caps.

Wheel arch liners and fender caps are functional plastic components fitted to a vehicle primarily to protect delicate components from road debris and to cover the wheel well for aesthetic purposes. Fender caps can also provide aerodynamic benefits, potentially reducing fuel consumption.

The products and processes used in the manufacture of the products listed in this standard must comply with requirements regarding worker and consumer health, worker safety, regulated substances, recycling, and environmental reporting.

The mandatory or recommended tests specified in this standard aim to ensure conformity to the specification, but the responsible organization is obliged to ensure that the component or system meets all applicable environmental, physical, electrical, mechanical, functional, regulatory and durability requirements, including all applicable system interface requirements described in the standard, for the entire specified useful life.

Stellantis PF.90152 standard is an internal performance specification. It defines environmental durability and performance requirements for automotive components, particularly plastics, trim, and interior and exterior parts. This standard is widely applied in validation tests (design validation/manufacturing validation phases) to ensure components can withstand real-world operating conditions throughout the vehicle's lifespan.

The Stellantis PF.90152 standard applies to a wide range of automotive parts, including:

• Interior plastic components (instrument panels, upholstery)
• Outer polymer parts
• Assemblies exposed to environmental stress.
• Components requiring thermal and climatic verification.

This standard is widely referenced in component drawings and verification plans.

This standard focuses on environmental simulation tests. Typical test methods include:

• Thermal shock test:
• Rapid transitions between high and low temperatures.
• It evaluates resistance to cracking, deformation, or layer separation.
• It ensures material integrity under sudden climate changes.
• Thermal cycling test:
• Repeated exposure to alternating temperature extremes.
• It simulates long-term seasonal conditions.
• It monitors fatigue behavior and material aging.
• Moisture resistance test:
• Exposure to high humidity and condensation.
• It evaluates swelling, corrosion effects, and loss of adhesion.
• It is critical for parts that are close to internal and electronic components.
• Cold impact resistance test:
• Mechanical impact at low temperatures
• It determines brittleness and fracture resistance.
• Dimensional stability test:
• Measures deformation after thermal or moisture exposure.
• It ensures suitability, assembly compatibility, and visual quality.

The main objectives of the Stellantis PF.90152 standard are as follows:

• To ensure the long-term durability of the materials.
• To prevent failure modes such as cracking, bending, or delamination.
• To verify functional and aesthetic performance.
• To support global platform standardization across Stellantis brands.

This is consistent with the broader Stellantis reliability principles, where robustness and failure mode prevention are fundamental engineering goals.

The Stellantis PF.90152 standard is commonly used in conjunction with the following standards:

• Material properties (plastics, elastomers)
• Durability and reliability guidelines
• Component-specific standards (e.g., Stellantis PF.90088 standard for air systems)

Together, these form a comprehensive validation framework encompassing materials, design, and performance.

In a real automotive project, the Stellantis PF.90152 standard is applied in the following stages:

• Design verification (DV test)
• Process validation (PV testing)
• Supplier approval and release

This standard is used for the following purposes:

• Defining test plans
• Determine acceptance criteria
• Approve or reject components

The Stellantis PF.90152 standard is essential because it ensures automotive components operate reliably in real-world conditions throughout the vehicle's lifespan. This standard is considered important for the following reasons.

• Ensures component durability: Automotive parts, especially plastics, coatings, and interior and exterior components, are exposed to extreme temperatures, humidity, and mechanical stresses. This standard defines the following tests:
• Thermal shock
• Exposure to moisture
• Cold Strike
• Dimensional stability
• It maintains quality and conformity: Deformed or faulty parts can cause assembly problems, rattling, misalignment, or visual defects. This standard ensures that...
• It guarantees dimensional stability.
• Provides a proper fit and finish.
• It prevents functional failure of components in vehicles.
• Supplier and production control: This standard serves as a benchmark for supplier qualification:
• Suppliers must meet the requirements before approval.
• It defines acceptable limits and test methods.
• It helps identify weak materials or designs early in the development process.
• Customer satisfaction and brand reputation: A car with cracked coatings, deformed plastics, or faulty components leads to customer dissatisfaction. By implementing this standard:
• The vehicles retain their appearance and functionality.
• Long-term reliability is ensured.
• Stellantis protects its brand image and reduces warranty claims.
• Compliance with global standards: This standard is consistent with international durability practices and ensures that parts,
• It ensures that it meets global regulatory expectations.
• It ensures safe use in various climates (hot, cold, humid, dry).
• Reduces the risk of safety or comfort malfunctions.

In conclusion, the Stellantis PF.90152 standard is a critical environmental durability standard that ensures automotive components survive in harsh real-world conditions. By defining structured tests such as thermal shock, moisture exposure, and dimensional stability, it plays a vital role in:

• Product safety
• Supplier quality control
• Long-term vehicle performance
