Odor smell test standard case and odor test method implemented by the aid of same

Abstract

The invention discloses an odor smell test standard case and an odor test method implemented by the aid of the same. The odor smell test standard case comprises a constant-temperature chamber, a smell and odor chamber, a sample container, a reference container or reference pipeline, a flow meter, a gas control valve, a clean gas source supply device and standard-grade gas source supply devices. The sample container and the reference container or reference pipeline are positioned in an identical constant-temperature chamber environment, sample gas emitted when test samples are heated and reference gas with different odor grades can be exhausted into the smell and odor chamber, and a test person in the small and odor chamber can compare and detect odor, so that odor grades of the sample gas can be evaluated. The odor and smell test standard case and the odor test method have the advantages that the odor of the gas emitted by the test samples can be evaluated and tested in the unified standard test environment according to the reference gas with the different odor grades, the odor smell test standard case and the odor test method are free of influence of external environments, accordingly, the test accuracy and reliability can be guaranteed, the gas can be conveniently and easily tested and can be tested only by the single test person, and errors due to the fact that odor is tested by different test persons or is tested by the same test person at different times can be prevented.

Description

technical field [0001] The invention relates to the technical field of odor testing equipment, in particular to an odor smell test standard box and an odor testing method thereof. Background technique [0002] In the automobile manufacturing industry, odor evaluation tests are required for automobiles or their parts and materials. Traditional odor evaluation methods generally use human body scoring methods, such as odorless / odor / pungent. However, its subjectivity is too strong, and people's sense of taste will produce large errors with changes in time, temperature, environment, wind speed, etc., and the residual memory of smell in the human brain is uncertain, which will also affect the scoring, so multiple tests are usually required This test method is relatively cumbersome. [0003] At present, although some smell test equipment can be used to identify the intensity of the smell, the existing smell test methods do not have a uniform and standard environment, and are grea...

Problems solved by technology

However, its subjectivity is too strong, and people's sense of taste will produce large errors with changes in time, temperature, environment, wind speed, etc., and the residual memory of smell in the human brain is uncertain, which will also affect the scoring, so multiple tests are usually required Comprehensive assessment by personnel, this test method is more cumbersome

[0003] At present, although some smell test equipment can be used to identify the intensity of the smell, the existing smell test methods do not have a uniform and standard environment, and are greatly affected by the external environment, so the accuracy of the test cannot be guaranteed
