FOGGING TEST IN THE
AUTOMOBILE INTERIOR

The fogging test is an essential test for materials used in vehicle interiors. It ensures that your components do not release unwanted volatile substances that could deposit on windows or other surfaces. The fogging test is an essential test for determining the outgassing of volatile organic compounds (VOCs) from materials in the vehicle interior. It ensures that emissions, which can appear as fog or mist on cold surfaces such as windscreens, are minimized to ensure driver visibility and safety. These deposits can not only impair visibility, but also reduce the perceived quality and comfort in the vehicle.

ENSURING THE DURABILITY OF VEHICLE MATERIALS

In the vehicle interior, materials such as textiles and leather are exposed to heavy wear and tear from clothing and objects on a daily basis. This can lead to wear, discoloration and tears, especially in high-traffic areas such as seats, armrests or steering wheels. Abrasion and scuffing tests are crucial for evaluating these influences and identifying potential weak points at an early stage. Our test methods can therefore make a significant contribution to the quality and durability of the materials used.

With the increasing demand for sustainable materials, the requirements for these tests are also increasing. Suppliers and OEMs must ensure that these innovative materials meet the high requirements of the automotive industry.

FAQ

Frequently asked questions about the fogging test

What is the fogging test? The fogging test measures the release of volatile substances from materials that can form deposits on surfaces such as windows.

How long does a fogging test take? As a rule, you will receive the results within a few days, depending on the complexity of the materials.

What do I do if the exam is negative? We offer you comprehensive advice and recommendations to take appropriate measures and find alternative materials.

What sample quantities are required for a fogging test?

The sample quantities required for a fogging test depend on the standard and the test method used. Here are the general guidelines:

1. standard DIN 75201 (type A and type B)

Type A (glass plate method):
A sample quantity of 10 cm² is typically required. The sample is placed on a heated plate in a sealed chamber and the volatiles released condense on a glass plate above.
Type B (aluminum foil method):
Similar to type A, a sample volume of approximately 10 cm² is used. However, the volatile substances condense on a cooled aluminum foil.

2. standard ISO 6452 (international standard)

Sample quantity:
Again, a sample size of about 10 cm² is typically required to evaluate the amount of volatiles released at elevated temperature.

3. other specific requirements

Depending on the specific requirements of the customer or OEM standards, sample quantities may vary. It is important to check the respective standards or test requirements carefully.

What is the difference between the reflectometric and gravimetric test method according to DIN 75201?

Method A - Reflectometric method:

Principle: This method measures the change in reflectivity on a glass plate on which volatile components from the material sample are deposited.
Procedure: A material sample is heated in a beaker while a glass plate above it is cooled to 21°C. The temperature difference causes the volatile components to condense on the glass plate. The reflectance index of the fogged glass plate is then measured to determine the amount of condensed material.
Application: This method is particularly suitable for materials for which an exact determination of the optical fog effect is required.

Method B - Gravimetric method:

Principle: This method measures the weight of condensed volatiles on an aluminum foil.
Procedure: The material sample is heated in a beaker while an aluminum foil disc is cooled to 21°C. After 16 hours, the amount of condensed material on the foil is weighed.
Application: This method is ideal for an accurate quantitative determination of the amount of condensed volatiles.

FAQ

FREQUENTLY ASKED QUESTIONS ABOUT WEAR TESTS

Why are textiles tested for wear? In vehicle interiors, materials such as textiles and leather are exposed to daily stresses from clothing and objects, which can lead to wear, discoloration and tears - especially in heavily used areas such as seats, armrests and steering wheels. Abrasion and scuffing tests help to evaluate these stresses and identify weak points at an early stage. In this way, our test procedures make a decisive contribution to the quality and durability of the materials.
