Ford FLTM BI 104-01 Immersion test for painted parts and panels.
Ford FLTM BI 104-02 Condensation Vapor Test
The “Ford FLTM BI 104 Automotive Paint Water Immersion and Moisture Resistance Test” standard, developed by Ford Motor Company (Ford), describes a set of test methods used to evaluate the resistance of painted automotive components and paint systems to water exposure, immersion, condensation, and moisture-related degradation. This standard primarily applies to painted metal and plastic parts to ensure long-term durability under environmental conditions encountered during vehicle servicing.
The Ford FLTM BI 104 standard family includes the following sub-sections:
Automotive coatings are constantly exposed to the following:
Over time, moisture can penetrate coating systems and cause:
The Ford FLTM BI 104 standard evaluates how well coating systems withstand these conditions and how well they retain their protective and decorative functions.
Ford FLTM BI 104-01 Immersion test for painted parts and panels.
This standard includes a test method used to evaluate the resistance of painted metal and painted plastic components to degradation from prolonged water exposure. The standard aims to determine whether automotive coating systems can maintain their appearance, adhesion, and protective properties when submerged in water.
Automotive coatings are regularly exposed to rain, standing water, condensation, road spray, and car washes. Moisture penetration can lead to the following types of coating failures:
This standard helps identify these potential failures before materials are approved for vehicle manufacturing.
The described test method is applicable to the following:
This standard is widely used in supplier approval, coating development, and production verification programs.
This standard is commonly used in the following areas:
To provide a comprehensive assessment of environmental durability, this standard is often used in conjunction with other Ford paint durability standards such as Ford FLTM BI 103-01 Salt spray resistance and Ford FLTM BI 104-02 Condensed water vapor test.
In conclusion, the Ford FLTM BI 104-01 standard is a fundamental environmental durability test for painted automotive parts. By exposing painted parts and panels to controlled submersion conditions and evaluating defects such as blistering, loss of adhesion, discoloration, and coating degradation, this method helps ensure that automotive paint systems remain durable, attractive, and protective throughout the vehicle's lifespan.
Ford FLTM BI 104-02 Condensation Vapor Test
This standard includes a test method used to evaluate the resistance of painted and coated automotive materials to prolonged exposure to condensing water environments. By simulating high-humidity conditions where water continuously condenses on vehicle surfaces, this standard allows engineers to assess coating durability, adhesion, and moisture resistance.
Automotive coatings are frequently exposed to environments where moisture condenses on the surfaces. For example,
Under these conditions, moisture can penetrate the coating systems and lead to the following:
This standard accelerates these effects in a laboratory setting to predict long-term field performance.
This standard is primarily designed for the following:
This test, which relies on condensation forming on the sample surface, is designed for flat panels that act as the roof of the condensation chamber.
In principle, the method exposes the coated panels to a hot, saturated atmosphere. Water vapor continuously condenses on the test surface, forming a thin film of moisture. Unlike immersion testing, the samples are not submerged in water. Instead, they are subjected to a continuous condensation cycle similar to real-world moisture exposure.
In short, the Ford FLTM BI 104-02 standard is a specialized environmental durability test that evaluates how painted automotive surfaces perform when exposed to continuous or cyclical condensation. By simulating high-humidity operating environments and monitoring defects such as blistering, dulling, corrosion, and loss of adhesion, this method helps automotive coating systems provide reliable long-term protection and appearance throughout a vehicle's lifespan.
Ford FLTM BI 104-04 Adhesion/Immersion Test
This standard includes a test method used to evaluate the adhesion performance of electroplating and topcoat paint systems on phosphated steel panels before and after immersion in hot water. This standard determines whether a coating system can maintain adequate adhesion when exposed to moisture, a critical requirement for long-term corrosion protection and appearance durability.
The primary purpose of the Ford FLTM BI 104-04 standard is to measure the relative adhesion of automotive paint systems and to determine how water exposure affects the bond between them.
This method helps identify coating systems that may experience the following problems:
Loss of adhesion
Peeling
Layer separation
blistering
Early corrosion after exposure to moisture.
This standard is primarily designed for the following:
This standard is commonly used in material qualification assessment, supplier approval, paint development, and quality control programs.
In principle, the test compares the adhesion of the coating before and after immersion in hot water. During the test, a cross-pattern is cut from the coating to the substrate, adhesive tape is applied and removed, and the amount of coating removed is evaluated. The process is repeated after immersion in water to determine if the coating bond is affected by moisture.
In conclusion, the Ford FLTM BI 104-04 standard is a specialized adhesion strength test that measures the ability of electroplated and topcoat automotive paint systems to maintain their adhesion after immersion in hot water. By combining controlled water exposure with cross-screen tape testing, this method provides an effective assessment of moisture-induced coating degradation and serves as a key quality and validation tool in Ford’s paint and corrosion engineering programs.
