Stationery Testing

Service Background

We often need to use a variety of stationery and educational supplies in offices or learning. But the quality of stationery products are uncertain, such as pen cap safety failure leading to asphyxiation of children, exercise book paper too bright/white injuring children's eyes, the content of benzene in the correction fluid too high to cause cancer. The safety of stationery is also the focus of the annual random inspection by the quality supervision department. In order to better control the quality of stationery, domestic and European/American all have set their own regulations and standards.
