二 Children's furniture size inspection
Main size requirements for children's furniture:
三 Physical and chemical performance testingof children's furniture
四 Children's furniture structural inspection
1.Outside corner
The dangerous outer corners of children's furniture that are accessible under normal use (see the circled position in Figure 1) should be rounded, with a radius of not less than 10 mm, or a rounding arc length of not less than 15 mm.When the product instructions clearly state that the product needs to be placed against the wall and connected to the wall, the outer corner of the product on the wall side does not need to be rounded.
2. Accessible dangerous sharp edges
The edges of accessible rigid materials on the product are tested as sharp edges and should not be hazardous sharp edges.Without the use of special tools, the bolt threads on the product expose an accessible edge simply by turning the knob, and this edge should also pass the sharp edge test.
3. Accessible dangerous sharp points
The points of accessible rigid materials on the product are tested as sharp points and should not be hazardous sharp points.
4. Dangerous protrusions
The product should not have dangerous protrusions. If there are dangerous protrusions, they should be protected in appropriate ways. For example, bend the end or add a protective cap or cover to effectively increase the area that may come into contact with the skin.
5. Holes, gaps and openings should meet the following requirements:
For holes, holes and gaps in the rigid material of the product with a depth exceeding 10 mm, the diameter or gap shall be less than 7 m or greater than or equal to 12 mm according to the test; the openings of all accessible tubular parts on the product shall be closed with a sealing cover or cap; Conduct a tensile test on the protective parts to ensure they do not fall off.
