SJ/T 11610-2016 VOC release test chamber test procedure

Edit | huanyi instrument

voc release test box can detect the amount of voc release in electronic and electrical products. Using voc release test box for testing can be divided into four steps: pre-operation, adsorption, sampling and calculation.

voc release test chamber test process:

I. Equipment sample preparation:

Test equipment: voc release test chamber

Device model: huanyi Instrument HYV-1000

Sample: electronic and electrical products

Ii. Test process:

1. Pre-operation: The equipment under test should be energized and maintain 1-4 times of air exchange at this stage.

2. Adsorption: Tenax TA should be used for treatment and analysis to minimize the release of the target test substance (especially benzene) in the artificial product. 2, 4-dinitrophenylhydrazine (DNPH) can be used as adsorbent for aldehydes and ketones.

3. Sampling:

a. In the pre-run phase, (100~200) ml/min. The sampling time starts from 20 minutes before the end of the pre-run phase to 1 hour after the end of the pre-run.

b. In the running stage, set the sampling flow as (100~200)ml/min in the later running stage, and the sampling time lasts for 1 air exchange.

4. Calculation: According to the actual situation, the calculation formula required in SJ/T 11610-2016 is adopted for calculation.
