Embodiment Construction

[0035] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] see figure 1 and figure 2 As shown, the odor evaluation method of automotive interior parts includes the following steps:

[0037] Step 1. Preparation of odor evaluation bag

[0038] 1. The odor evaluation bag 5 has only one end opening, and the opening is sealed by a sealing strip 6, and an inflatable switch 7 is arranged on the odor evaluation bag, and the odor evaluation bag 5, the sealing strip 6 and the inflatable switch 7 are all made of polytetrafluoroethylene Made to meet the requirements of the material having no peculiar smell and being able to withstand temperatures above 150°C.

[0039] ② Check the airtightness of the odor evaluation bag 5 by vacuuming to ensure that the airtightness of the odor evaluation bag 5 is good.

[0040] ③Before use, the odor evaluation bag ...

Abstract

The invention discloses an odor evaluation method for automotive interior parts. Through larger sample sizes and higher test requirements, discrimination of an odor source is increased, so that contribution of a part assembly to the odor of the whole automobile can be investigated more visually. Compared to odor evaluation on material types, the method can quickly locate the whole automobile odor contribution source and achieve odor change, so that the problem of misjudgment caused by poor local homogeneity of constituent materials of the parts is effectively solved, and detection missing of a small number of the constituent materials or auxiliary materials of the complicated part assembly is prevented.

Description

technical field [0001] The invention relates to the field of air quality control in automobiles, and more specifically relates to an odor evaluation method for automobile interior parts. Background technique [0002] The problem of air quality in the car has attracted more and more attention from users. When people subjectively feel the air pollution in the car, they always feel the smell in the car. In 2008 and 2011, the state issued the test methods and limit values ​​of air pollution in the car, but did not specify the rating method and acceptance criteria for the smell in the car. [0003] At present, in order to improve the air quality in the car, most automobile OEMs are borrowing or referring to the odor evaluation method of German VDA270, and use 1L or 3L glass odor bottles to conduct odor subjective evaluation tests. Such as image 3 As shown, the scent bottle 1 is made of glass material to make the bottle body 3, and has a bottle cap 2 that can seal the scent bott...
