As the stationery products frequently used by students every day, the quality of the products directly affects the children's health and even life safety, and the quality and safety control of stationery is becoming more and more strict. On February 25, 2005, the European Commission officially announced EN71-9: requirements for organic chemicals.
The standard gb21027-2007, jointly issued by many ministries and commissions, has been officially implemented on April 1, 2008. It puts forward the standard requirements for stationery safety and the basis for stationery testing standards. "General requirements" is a compulsory general standard. Products that do not meet the technical specifications and safety standards will not be sold on the market.

■ limit the brightness of students' book;
■ safety regulations on the size of pen caps;
■ The edge of hand scissors, blade, pencil sharpener, drawing ruler, stationery box, etc. are specified.
Physical testing
Pen testing
