Ford DVM-0039 Insect Repellent Resistance Test

The “Ford DVM-0039 Insect Repellent Resistance Test” standard, developed by Ford Motor Company (Ford), is a materials testing specification used to evaluate the resistance of automotive interior and exterior materials to insect repellents. This standard primarily applies to plastics, coated surfaces, painted components, synthetic leather, textiles, and decorative trim pieces that may come into contact with insect repellent products during normal vehicle use.

This test belongs to Ford’s family of chemical resistance standards and complements the “Ford DVM-0036 Sunscreen Resistance Test” standard. Both standards are frequently required to verify interior upholstery materials because consumers often use sunscreen and insect repellent while driving or traveling.

The purpose of the Ford DVM-0039 standard is to determine whether a material can withstand exposure to insect repellent chemicals without experiencing the following conditions:

• Surface discoloration
• Staining
• Reduced brightness
• Softening
• Swelling
• Cracking
• Loss of adhesion
• Changes in texture or appearance
• Coating deterioration

Many insect repellents contain aggressive active ingredients, such as solvents, that can damage automotive plastics and coatings. If materials are not properly verified, even brief contact can cause permanent damage to sensitive surfaces.

The described test method is a chemical resistance testing method in which a defined insect repellent formulation is applied to a test sample under controlled conditions. The sample is then exposed for a specific period of time and evaluated for visual and physical changes. Typical evaluation criteria include:

• Applying insect repellent to the surface of the material.
• Controlled exposure time and environmental conditions.
• Removal of the test environment.
• Visual inspection.
• Evaluation of color, brightness, texture, and surface integrity.
• Comparison with Ford's acceptance requirements.

The Ford DVM-0039 standard commonly applies to the following types of materials:

• instrument panels
• Door trims
• Center consoles
• Painted interior components
• Decorative coatings
• Soft-touch surfaces
• Faux Leather
• Vinyl materials
• Plastic molds
• Steering wheel covers
• Exterior painted trim components

The Ford DVM-0039 standard is often used in conjunction with the following standards:

• Ford DVM-0036: Sunlight Resistance
• Ford DVM-0017: Contamination and Cleanability Behavior
• Ford DVM-0019: Scratch resistance
• Ford DVM-0033: Cold weather performance
• Ford DVM-0058: Exterior surface gloss durability

These standards collectively assess the ability of automotive materials to withstand real-world environmental and consumer product exposures.

Materials that do not meet the requirements of the Ford DVM-0039 standard may fail. Typical failure modes include:

• Whitening or blooming
• Surface adhesion
• Loss of brightness
• color change
• Surface swelling
• Coating blistering
• Soft-touch coating deterioration
• Permanent staining
• Reduced adhesion of decorative layers

Such defects can significantly affect both the appearance and perceived quality of the vehicle.

The Ford DVM-0039 standard is necessary because it verifies that automotive materials can withstand contact with insect repellents without cosmetic or functional damage. Modern insect repellents often contain strong solvents that can damage plastics, coatings, synthetic leather, and painted surfaces. This standard is considered important for the following reasons:

• It prevents damage from everyday consumer products: Vehicle occupants often apply insect repellent before driving, camping, hiking, or traveling. Residue of insect repellent on hands, arms, or clothing can transfer to steering wheels, instrument panels, door panels, center consoles, armrests, and seat upholstery: Without sufficient chemical resistance, these components can stain, discolor, or deteriorate.
• It preserves the vehicle's appearance: Interior appearance is a significant factor in a customer's perception of quality. Insect repellents can cause: loss of gloss, whitening, surface softening, permanent stains, and discoloration. This standard ensures that materials retain their original appearance after exposure.
• Improves material durability: Chemical attack from insect repellents can weaken polymers and coatings over time. This standard helps verify that, throughout the vehicle's lifespan, the materials retain their properties.
  • Surface integrity
  • Mechanical durability
  • Coating adhesion
  • Texture and sensation
• It reduces warranty claims and customer complaints: Customers often consider chemical damage to internal parts as a manufacturing defect. Material testing under this standard helps Ford identify sensitive materials before production, thereby reducing:
  • Warranty costs
  • Spare parts costs
  • Customer dissatisfaction
  • Brand reputation risks

Supports global vehicle use: Ford vehicles are also sold in regions where insect repellent use is common, including tropical climates, coastal areas, camping and recreation markets, and areas with high mosquito populations. This standard ensures consistent material performance regardless of geographic location.

• Validates new materials and coatings: Automotive manufacturers are constantly introducing new polymers, soft-touch coatings, decorative films, and sustainable materials. This standard provides a standardized method for comparing and approving these materials before they are used in production vehicles.

Part of real-world chemical resistance validation: Vehicle interiors are exposed to numerous consumer chemicals throughout their lifespan. This standard works in conjunction with other Ford standards that assess resistance to substances such as sunscreens, cosmetics, hand sanitizers, cleaning agents, foods and beverages, and body oils and sweat. Together, these tests simulate the realistic conditions customers encounter every day.

In short, the Ford DVM-0039 standard is important because it ensures vehicle materials remain attractive, durable, and functional even after exposure to insect repellents. This standard helps prevent staining, discoloration, softening, and coating failure, ultimately improving vehicle quality, customer satisfaction, and long-term durability.

In conclusion, the Ford DVM-0039 standard is a crucial chemical resistance standard used to ensure automotive materials can withstand accidental contact with insect repellent products. By evaluating resistance to aggressive consumer chemicals, the test helps protect the vehicle's appearance, durability, and customer satisfaction throughout its lifespan. Along with sunscreen and other environmental resistance tests, this standard forms a critical part of Ford's material validation process for interior and exterior components.
