RoFoam odor test
Quality assurance for automotive interiors

When materials are used in the automotive industry, not only technical performance and safety matter. Odor perception is a key factor as well: unwanted or disturbing smells inside a vehicle interior can have a considerable negative impact on the user experience. That is why we subject our RoFoams to odor testing in accordance with the VDA 270 standard.

What is the VDA 270 standard?

VDA 270 is a standardized method for evaluating the odor characteristics of interior trim materials in vehicles. Its purpose is to ensure that materials comply with the highest OEM standards for comfort and quality.

How does the test procedure work?

The test is conducted under controlled conditions: RoFoam samples are placed in special glass jars and then heated in an oven at 80°C for 4 hours. After heating, the jars are cooled for 10 minutes to approximately 60°C. At least three panelists then evaluate the samples by briefly lifting the lid and smelling them. The odor is assessed on a six-point scale:

1.    not perceptible
2.    barely perceptible, not disturbing
3.    clearly perceptible, not disturbing
4.    disturbing
5.    strongly disturbing
6.    nauseating

The test result is considered valid if the panelists give the same rating or if their scores differ by no more than one point. In such cases, the average rating is used.

What does this mean for our customers?

The odor test is a key element of quality assurance at Schmitz Foam Supply. Our RoFoam solutions consistently meet the highest standards for both performance and sensory comfort. Test results show that RoFoams always achieve a rating of 3 or lower. Meaning any odor is at most clearly noticeable, but never disturbing. This ensures our customers can rely on RoFoams to be free from unwanted odors while fully meeting the strict requirements of the global automotive industry.
