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
The present invention relates to vehicle air quality management and control field, more specifically to a kind of Odor Evaluations method of automotive trim parts.
Background technology
In-car air quality problem more and more receives the concern of user, and people experience smell in car.Country at 2008 and successively issue in 2011 testing method and limits of in-vehicle air pollution, but in non-regulation car smell ranking method with accept standard.
Present most of automobile main frame maker, for improving air quality in vehicle, is all using or with reference to the Odor Evaluations method of German VDA270, is adopting 1L or 3L glass odor bottle to carry out smell subjective assessment test.As shown in Figure 3, this odor bottle 1 adopts glass material to make bottle 3, and can the bottle cap 2 of airtight odor bottle with one, this bottle cap 2 can use the resistant to elevated temperatures sealing strip composition of the making of the material of glass tape frosted or glass cover and free from extraneous odour, quantitative standard model 4 is loaded in bottle 3, then at three temperature (23 DEG C, 40 DEG C, 80 DEG C), odor evaluation test is carried out respectively, the odor dispersion situation of simulated automotive under indoor temperature, outdoor temperature and high-temperature condition.Because the method only intercepts quantitative standard model 4 to automotive trim parts/material, in the good situation of material homogeneity of interior trim parts/material, the method can well the raw-material odor dispersion situation of across comparison unlike material or different manufacturers, but if test sample material homogeneity is bad just there will be larger erroneous judgement.When current domestic technology is low and cost control is strict, the homogeneity that material is good also cannot be accomplished.In addition, because the method is material level test evaluation, if the smell source of certain car load need be investigated, then need to investigate one by one the hundreds of kind composition starting material of parts all in car, experimental project amount is huge, add the reason that material homogeneity is bad, adopt the method to bring larger difficulty to the smell investigation of car load and rectification.
Summary of the invention
The object of this invention is to provide a kind of Odor Evaluations method of automotive trim parts, to solve car interior trim parts because material homogeneity is bad, parts material composition is complicated, existing material level Odor Evaluations method is adopted to be difficult to investigate the problem in car load smell source.
The Odor Evaluations method of automotive trim parts of the present invention, comprises the following steps:
The preparation of step one, Odor Evaluations bag
1. Odor Evaluations bag only has one end open, and this opening is sealed by sealing strip, and is provided with gas-filled switching tube on Odor Evaluations bag, described Odor Evaluations bag, sealing strip and gas-filled switching tube by free from extraneous odour and the material of resistance to more than 150 DEG C temperature make.
2. guarantee that the impermeability of Odor Evaluations bag is good;
3. be the burin-in process of under the condition of 80 DEG C, Odor Evaluations bag being carried out at least 24h in temperature.
The preparation of step 2, parts to be measured
Load in the polybag of free from extraneous odour by surveying parts, after sealing, the constant temperature and humidity being placed into clean free from extraneous odour is indoor, temperature be 23 ± 2 DEG C, relative humidity places 24h under being the condition of 50% ± 5%.
Step 3: parts pack to be measured
1., at clean free from extraneous odour and in draughty laboratory, parts to be measured are loaded in Odor Evaluations bag, avoids parts to be measured to be polluted;
2. with reference to form one, the size according to parts to be measured is filled with quantitative pure air in Odor Evaluations bag.
Form one
| Smell bag type | Class1 | Type 2 | Type 3 | Type 4 | Type 5 |
| Smell bag size (long × wide) | 35×35cm | 70×60cm | 120×120cm | 190×110cm | 200×128cm |
| Filled volume | 3L | 15L | 60L | 150L | 300L |
Step 4: constant temperature smell discharges
The Odor Evaluations bag that parts to be measured are housed is put into free from extraneous odour and with the constant temperature oven of air filtering system, be 60 ± 1 DEG C in temperature, 4h ± 0.2h carries out constant temperature process.
Step 5: smell subjective assessment
Under taking-up Odor Evaluations bag is placed on room temperature environment, when parts temperature is down to 50 ± 1 DEG C, slipper seal bar opens the opening of 10 ± 1cm width by one of Odor Evaluations bag jiao, evaluation personnel nose is from this extended distance 5 ± 1cm, outwards push Odor Evaluations bag, gas is overflowed, and evaluation personnel make oder levels and pass judgment in 10s.
Odor Evaluations requires:
1. Odor Evaluations personnel need through specialty smell the person of debating training and examine qualified.
2. an Odor Evaluations at least needs 3 evaluation personnel, if the evaluation result difference of the personnel of evaluation is greater than 1 grade, needs to substitute and reappraises, until the evaluation result difference of the personnel of evaluation is less than or equal to 1 grade.
Step 6: result evaluation
1. be final Appreciation gist with Odor Evaluations grade, level value shows that more greatly smell is larger, otherwise then less;
2. evaluation conclusion, is shown in form two; If final opinion rating is different, then take the principle that the minority is subordinate to the majority, get the grade that majority select.
Form two
| Grade | Feature interpretation |
| 1 | Smell is not discernable |
| 2 | Discernable, but very slight |
| 3 | Obviously discover, but can accept |
| 4 | Irritant smell, can not accept |
| 5 | There is intense stimulus smell, cannot stand |
Further, Odor Evaluations bag, sealing strip and gas-filled switching tube are made by teflon.
Further, in step 3, for sticking or have sharp-pointed parts to be measured, then pack again after carrying out parcel process with PTFE film or clean aluminium foil, PE gloves or other clean free from extraneous odour gloves during pack, must be worn.
The Odor Evaluations method of automotive trim parts of the present invention, the composition material efficiently solving parts causes the problem judged by accident because local homogeneity is bad, also prevent minority's composition material of complex parts assembly or the undetected problem of auxiliary material simultaneously.What add smell source by adopting the testing requirements of larger sample volume and Geng Gao distinguishes limit, can investigate the smell percentage contribution of parts assembly to car load more intuitively.Relative to the Odor Evaluations of material type, this method can quick lock in car load smell contribution source go forward side by side promoting the circulation of qi taste rectification.
