Ford FLTM BO 116-01 Interior Weather Resistance

The “Ford FLTM BO 116-01 Interior Weather Resistance” standard, developed by Ford Motor Company (Ford), describes a test method used to evaluate the weather resistance of vehicle interior materials to exposure to sunlight. This standard assesses how interior upholstery materials such as fabrics, plastics, vinyls, carpets, seat covers, and decorative surfaces respond to prolonged exposure to simulated solar radiation.

Because vehicle interiors are constantly exposed to sunlight through windows and windshields, materials can experience fading, discoloration, brittleness, cracking, gloss changes, and other forms of deterioration. The Ford FLTM BO 116-01 standard defines an accelerated method for predicting these long-term effects.

The primary purpose of this standard is to define the following:

• Color fastness of interior materials
• Resistant to fading and discoloration.
• Surface durability under simulated sunlight.
• Preservation of mechanical and aesthetic properties.
• Long-term appearance performance of interior trim components.

This standard helps ensure that materials maintain their intended appearance and functionality throughout the vehicle's lifespan.

In principle, this testing method uses a controlled-radiation xenon arc weather exposure device equipped with special optical filters and an auxiliary lamp system. Xenon arc technology closely reproduces the entire spectrum of natural sunlight, including visible and ultraviolet wavelengths.

During testing, samples are exposed to the following:

• Controlled light intensity
• high temperatures
• Simulated solar radiation
• Repeating cycles of light and dark

The changes that occur are evaluated through visual inspection and, where necessary, instrumental measurements such as color difference and brightness retention.

c is not an entirely independent procedure. In addition to the “SAE J 2412 Accelerated exposure of automotive interior trim components using a controlled irradiation xenon arc device” standard, it includes Ford-specific requirements for interior weather resistance assessment. Ford’s method incorporates specific filter requirements and exposure conditions designed to better simulate the solar environment inside Ford vehicles.

Materials frequently tested according to the Ford FLTM BO 116-01 standard include:

• Upholstery fabrics
• Leather and synthetic leather
• Instrument panel trims
• Door trim materials
• Ceiling tiles
• Carpet systems
• Decorative films
• Interior plastics
• Vinyl components
• Interior coverings and laminates

These materials are particularly susceptible to degradation from prolonged exposure to sunlight.

During testing, materials are examined from the following perspectives:

• Color fading
• yellowing
• Cracking
• Chalking on the surface
• Reduced brightness
• Fragility
• Layer separation
• Tissue changes

Any significant deterioration may indicate that the material is unsuitable for long-term automotive interior use.

Using the Ford FLTM BO 116-standard 01, manufacturers can do the following:

• It can reduce warranty claims related to interior appearance.
• It can increase customer satisfaction.
• We can verify material durability before production.
• Can objectively compare alternative materials.
• It can accelerate product development programs.
• It can provide consistent global quality standards.

Accelerated testing provides valuable information within weeks, instead of waiting years for results that depend on natural weather conditions.

The Ford FLTM BO 116-01 standard is important because it helps ensure that automotive interior materials can withstand years of exposure to sunlight, heat, and ultraviolet (UV) radiation without experiencing unacceptable degradation. This standard is considered important for the following reasons:

• Maintains the interior appearance: Occupants see and interact with interior components every day. Exposure to sunlight can cause discoloration, yellowing, loss of gloss, and surface changes. This standard verifies that the materials retain their original appearance throughout the vehicle's lifespan.
• It prevents premature material deterioration: UV radiation and heat can weaken many indoor materials, leading to:
  • Cracking
  • Fragility
  • Layer separation
  • Chalking on the surface

This standard helps identify materials that may spoil prematurely before being approved for production.

• It simulates real-world conditions: Vehicles parked outdoors can be exposed to intense sunlight for years. The xenon arc weather resistance test used in this standard accelerates these conditions in a laboratory setting, allowing engineers to predict long-term performance within a relatively short test period.
• Supports material selection: Automotive manufacturers often evaluate multiple suppliers and material formulations. This standard provides a consistent method for comparing:
  • fabrics
  • Vinyls
  • Skin
  • Plastics
  • Decorative flooring materials

This helps engineers select the most durable materials for vehicle interiors.

• It improves customer satisfaction: Customers expect interior components to remain attractive for many years. Fading or cracking materials can create a perception of low quality. Compliance with this standard helps to protect:
  • Vehicle aesthetics
  • Perceived quality
  • Brand reputation
  • Customer trust
• Reduces warranty and replacement costs: Indoor weather-related failures can lead to costly warranty claims and parts replacements. By identifying weaknesses during development, manufacturers can avoid expensive field failures and improve product reliability.
• It ensures global durability: Vehicles are sold in regions with very different climates, including desert environments. This standard ensures that interior materials perform consistently regardless of geographic location and sunlight intensity.

In conclusion, the Ford FLTM BO 116-01 standard is a critical durability standard for automotive interior materials. By using controlled xenon arc exposure to simulate years of sun exposure, the method helps engineers predict how interior components will perform over the life of a vehicle. This standard plays a vital role in maintaining the appearance, durability, and customer-perceived quality of Ford vehicle interiors.
