Before the introduction of "General Technical Conditions for Children's Furniture", the production and testing standards for children's furniture can only be applied to adults. Some brand manufacturers improve the environmental protection level of their products by using better raw materials. For example, "Yangtze River No. 7 Love Earth" children's furniture brand has been on the market for 3 years, and the standard used is also the national adult standard. The state requires the formaldehyde content to be less than 1.5mg / kg, while the company requires less than 1mg / kg.
Because children have active characteristics, they often touch the furniture with their hands and then suck their fingers. This common behavior can easily cause children to accidentally ingest a lot of harmful substances such as heavy metals. And children's absorption rate of heavy metals is very high, about 5 times that of adults. Therefore, in this new standard, in addition to the routine detection of the content of four toxic substances such as lead, mercury, chromium, and cadmium, children's furniture also requires the detection of the migrating elements antimony, barium, selenium, arsenic, etc.
The sales staff of "Colorful Life" for children's furniture told reporters that most parents would require environmental protection, but the main concern is the content of formaldehyde and whether it is made of solid wood. Little is known about heavy metal elements.
Emphasis: The two parts of the new standard, safety and warning signs, are mandatory requirements, and most of the existing products in the market are not in place
The safety of the design, which is also easily overlooked by consumers, is very strict in the new standard: "There should be no dangerous sharp edges and dangerous sharp tips, and edges and edges should be rounded or chamfered" and many more. After observing the market survey, the reporter found that some small brands and counterfeit goods have no design consciousness in this respect at all, and many big brands can't do it completely. In a well-known children's furniture brand store, the reporter saw that although their products have been passivated on the outer corners, they are still away from the new standard: all the outer corners under 1.6 meters are not less than 15mm in length. gap.
In addition, the new standard also stipulates that no glass can be installed on the ground or within 1.6 meters of the children's station. But the reporter found that many children's bookcases have glass doors or glass baffles in this area.
