identification can be carried out. The gas cultivation process is the same as
5.2.5.1.3.
b) After the packaged sample is placed in an oven, at a constant temperature of 65 °C
± 2 °C for 2 ~ 2.5 hours, the odor evaluator opens the air bag seal; close the nose
to about 2 cm ~ 3 cm away from the bag mouth, to slowly inhale the gas. Evaluate
and record the odor level of the parts assembly, according to the odor intensity
level described in Table 2.
c) After each odor evaluator conducts the odor evaluation, the air bag shall be closed

Sampling method for emission of volatile organic components and acetone
components in assemblies - Bag method
A.1 Sampling principle
Place the sampling bag, which contains the sample, in a temperature-adjustable oven,
to accelerate the rate of emission of volatile organic components in the sample, through
high temperature. After a certain period of time, the organic matter released from the
sample is qualitatively and quantitatively analyzed, by the gas collected in the bag.
