Determination of leather odor
This standard specifies the method for measuring the odor of leather in the presence of absolute substances when used in a single state. 2.1 Test chamber, omnidirectional glass holder, about 1L, the upper part is without depth, with suitable cover, the product should be connected and replaced,
2.2 Test environment, it has air circulation system, can keep the overflow at (65+3).3 Test environment
The tester should be operated in an environment where the smell is not emitted. The space should be ideal, but it is not necessary. 4 Test personnel
The tester should not be exposed to the light, smokers, people who use special fragrance cosmetics, users of traditional toxic or toxic tobacco products, etc. 3 Test personnel are not allowed to cooperate with the test.
5 Sampling and preparation of test specimens
Select only representative test pieces with a size of 125mm×00. 5.2 Air conditioning
Before the test, the specimens should be conditioned to an environment with a temperature rate of 23°C and a gradient of (50±5)% of 24HB procedure
8.1 For pollution control, the test specimens need to be air-conditioned before the test (including the lid), first rinse with hot water, then rinse with cold water, and dry once to keep them clean. 6.2 Test and respectively carry out double 10 state test under the conditions of · and ·, change the sample to the test defect, cover: need, for the state test, put the standard and 2-rate water or deionized water into the test chain: benefit on benefit, use an empty can, do empty self comparison, bzxZ.net
6.3 Put the empty user comparison, test error together with the pre-light adjustment of 65) supply 1 in the center. 1: The experimental temperature should be selected well, the 1 generation of ★ wet injection table test can not be done immediately, the effective body structure, under the full compliance, the personnel should slowly inhale the product into the test end, in order to reduce the risk of inhaling the open gas,
B.4 from the baking shot wide! ! For blank comparison, the first tester should put his head close to the blank comparison (about 15cm away) and remove the combustion seat. Then slowly inhale the air from the test barrier. Take out the lower test tank and quickly restore it to its original state: the test tank should be covered with a high stop cover. The test monitor should be kept in an environment where the gas supply is not contaminated.
6.5 Wait for 2mm sub-reflection 6.3 Account for retreat and select the trace of honest QB/T 2726--2005
6.6 Three steps of drying, test each sample, 6.7 to 6.4, 6.5, 6.6, the test time, the new product should be baked in the sticky, baking 15min: not less than 1 test person total test, change the effect of the above level of the barrier to a semi-definite level. Grade
The construction level of the steam zone meets the quality requirements of Mai 1.
