[GB/T 31106-2014, Definition 3.1]

3.2

total volatile organic compounds; TVOC

sum of organic compounds separated by a non-polar chromatography column (polarity index less than 10) and detected by gas chromatography, with a retention time between n-hexane to n-hexadecane (including n-hexane and n-hexadecane)

Note: It is revised version of Definition 3.2 of GB/T 31106-2014.

3.3

volatile organic compound content

mass of volatile organic compounds contained in a unit mass sample

3.4

volatile organic compound emissions

mass of volatile organic compounds released from a sample within specified time and space

3.5

volatile organic compound content sampling

process of collecting VOC in samples with head space method and using it for analysis

3.6

volatile organic compound emissions sampling

process of collecting VOC released from samples with climate chamber method or air bag method and using it for analysis

4 Classification

According to the category of the people who use stationery and sport products, the stationery and sport products may be divided into two categories: stationery and sport products for adults and those for children.

5 Requirements on VOC limit
