Volatile organic in electrical and electronic products Determination of compounds by gas chromatography-mass spectrometry

1 Scope

This standard specifies a small release test chamber for volatile organic compounds in electrical and electronic products - gas chromatography-mass spectrometry (GC-MS) test method. This standard applies to the determination of volatile organic compounds in electrical and electronic products.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Volatile organic compounds volatileorganiccompounds; VOC Sampling with 2,6 diphenylfuran porous polymer resin (Tenax-TA), using a gas chromatographic column with a polarity index of less than 10 An organic compound having a retention time between n-hexane and n-hexadecane. 2.2 Total volatile organic compound total volatileorganiccompound; TVOC Using Tenax-TA sampling, analysis was performed using a gas chromatographic column with a polarity index of less than 10, retention times in n-hexane and positive sixteen The sum of all organic compounds between the alkane. [GB/T 18883-2002, definition 3.2] 2.3 Air exchange rate airexchangerate The ratio of the volume of fresh air released in the test chamber to the volume of the empty release box per unit time. Note. The unit is hourly (h-1). 2.4 Air flow rate airvelocity Release the air flow rate measured in the test chamber. 2.5 Release test chamber smalchamber It consists of a cabin, an air circulation device, an air exchange device, an air purification device, a temperature and relative humidity control device, and a monitoring device. Test equipment with controlled operating parameters for simulating the release environment of volatile organic compounds. 2.6 Bearing rate loading factor The ratio of the volume of the test sample to the volume of the released test chamber.

3 Principle

The electrical and electronic products are placed in the release test chamber of certain conditions (temperature, humidity and air flow rate), and the volatilization of electronic and electrical products is released. The organic organic compound (VOC) is mixed with the air entering the release test chamber and discharged from the release test chamber outlet. The adsorption tube is used to release the test chamber.
