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.
