School Furniture Should Strictly Observe Five Special Indicators

- May 27, 2019-

1. Applicable age of school furniture label products

The applicable age of the product should be clearly indicated in the instructions for the use of school furniture, namely "3-6 years old", "3 years old and above" or "7 years old and above". The mechanical properties of school furniture in different age groups are different. As long as the school furniture in the age group of "7 years old and above" is included, the mechanical properties are more demanding.


2. Formaldehyde emission from wooden school furniture should be above Grade E1.

The amount of formaldehyde released refers to the requirement of GB18580. GB18580 clearly stipulates the emission limits of formaldehyde in interior decoration materials, wood-based panels and their products. Formaldehyde emission of various wood-based panels must reach level E1 before they can be used indoors.


3. Adding protective cover to dangerous outbursts

Classroom furniture should not have dangerous sharp edges and tips. It can touch the outside angle below the ground height of 1600 mm. The edges and edges need to be processed by chamfering or chamfering, and the radius of chamfering is not less than 10 mm, or the length of chamfering arc is not less than 15 mm. If dangerous protrusions exist, protective caps or caps should be added to protect them.


4. Closed classroom furniture must have ventilation function

When school furniture products have airtight and airtight spaces (such as doors or covers and other parts), and the enclosed continuous spaces are larger than 0.03 m3 and the internal dimensions are larger than or equal to 150 mm, a single opening area of 650 mm2, two unobstructed ventilation openings at a distance of at least 150 mm, or an equivalent area of two 650 mm2 should be set up. Ventilation openings, and doors can not be equipped with automatic locking device, opening force should be small.


5. The color of school furniture should not be too bright.

The new national standard limits antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium coated on the surface of school furniture, which increases by four kinds compared with adult furniture standards. Free formaldehyde in leather and textile fabrics must be 30mg/kg (higher than the standard of 75mg/kg for adult furniture), and the use of decomposable aromatic amines is prohibited (there is no requirement for adult furniture standard). In addition, phthalates in plastics are limited to less than 0.1%.
