3.3 Appearance
The nonwoven material shall not fray at the cut edges during processing and in later use.The material must be flexible enough to conform to the curves (radii) inside the car without formingcracks or folds.
The material must not become sticky either at room temperature or at +90 °C, and theimpregnation must not become brittle at temperatures down to -40 °C.The material must also be resistant to mold fungus in a moist heat climate.3.4 Physiological compatibility
The nonwoven material must be physiologically safe and must not induce skin irritation (e.g., due tofine fiber dust) or produce objectionable odors.
Substances that are emitted at elevated temperatures must be toxicologically safe.3.5
Identification according to VDA 260
Decorative nonwoven material: >PP+SBR Prior to testing, the specimens must be conditioned for at least 48 h in the DIN 50014 − 23/50-2standard climate.3.8 Evaluation of the measuring results The required numerical values apply to each individual measurement.
