| Résumé : |
Odor is an important criterion when buying a car. Until now, manufacturers and suppliers have analyzed odor using the noses of trained persons. However, different persons judge the same odor differently. Instrumental analysis can measure odors objectively and rigorously. Odor can thus be globally standardized and subsequently efficiently reduced. |
| Note de contenu : |
- The VOC-G method works differently
- Improving the odor of parts
- Measurement system analyses according to process 1 are also possible
- 7-day prediction by algorithm
- Fig. 1 : Structure of the olfactory pyramid, with graphical weighting of the individual intervals: Substances associated with the heart note are perceived more strongly than those from the other two regions
- Fig. 2 : The results of the VOC-G method and two panels for different materials show that the process provides very good results
- Fig. 3 : The measurements performed during production show that the deviations from the mean value are very small. The human panel, on the other hand, has no means of distinguishing such small nuances
- Fig. 4 : Checking of the 7-day prediction shows that the values agree very well with panel test values for materials that had been preconditioned for 7 days
- Table : Rating table of the odor intensity according to VDA 270 |
