Description
Technical field
It is to be related to a kind of olfactive testing standard more specifically the present invention relates to smell test equipment technical field
Case and its smell method of testing.
Background technology
, it is necessary to carry out smell assessment test to automobile or its parts and material in the manufacturing of automobile.Traditional
Smell appraisal procedure is typically using human body marking mode, such as odorlessness/odorous/pungent marking.But its subjectivity is too strong,
And the sense of taste of people can produce larger error with the change such as time, temperature, environment, wind speed, to smell residual in people's brain
Memory is uncertain, can also influence marking, therefore generally needs the several testers to carry out comprehensive assessment, and this method of testing is more
It is cumbersome.
At present, although can by some Olfactometry equipment go recognize smell intensity, but existing smell test
The environment that method is not sought unity of standard, is affected by the external environment larger, it is impossible to ensure the accuracy of its test.
