this Edition, Chapter 3 of Edition 2008);

- Add the requirements for bonding wires and test sequences (see 4.2 and 4.3 of this

Edition);

- Change the test tolerance (see 4.4 of this Edition, Chapter 3 of Edition 2008);

- Change the provisions on test ground (see 5.7 of this Edition, 4.5 of Edition 2008);

- Change the provisions on test lever (see 5.8 of this Edition, 4.6 of Edition 2008);

- Delete G-clips and hooks (see 4.7 and 4.8 of Edition 2008);

- Add the provisions on test equipment for weights, small torso plug gauges, leg plug

gauges, wedge blocks and so on (see 5.10, 5.11, 5.13, 5.14 of this Edition);

- Delete the test method for corrosion resistance (see 5.2 of Edition 2008);

- Change the material and structural appearance inspection methods (see 6.1 of this

Edition, 5.3 and Annex A of Edition 2008);

- Add the handrail impact test method (see 6.2 of this Edition);

- Add the test method for locking mechanism durability (see 6.3 of this Edition);

- Add the test method for small parts (see 6.5 of this Edition);

- Add dimensions of openings, gaps, and holes in components and methods for their

determination (see 6.6 of this Edition);

- Change binding system determination method (see 6.7 of this Edition, 5.4 and 5.5

of Edition 2008);

- Change the determination method for high chair stability (see 6.15 of this Edition,

1 Scope

This Standard specifies the test methods for assessing the safety performance of

children's high chairs.

2 Normative references

The following referenced documents are indispensable for the application of this

document. For dated references, only the edition cited applies. For undated references,

the latest edition of the referenced document (including any amendments) applies.

GB/T 531.1, Rubber vulcanized or thermoplastic - Determination of indentation

3 Terms and definitions

There are no terms and definitions that need to be defined in this document.

4 General test conditions

Children's high chairs are tested as delivered. If the high chair is detachable, it shall be

assembled according to the instructions for use.

The high chair joint line is shown in Figure 1.

When the seat and the seat back are in contact, it is the connection between the seat and

the seat back. When the seat and seat back are not connected, the joint line is the

projection line of the seat back on the seat (see Figure 1).

5 Test equipment and facilities

Test model is a rigid cylinder with a diameter of 200mm, a height of 300mm and a mass

of 15kg. The height of its center of gravity from the bottom is 150mm. The rounding

radius of all sides of the cylinder is 5mm. There are two seat belt anchorage points. The

height from the bottom is 150mm. The points circumferentially 180° to each other (see

Figure 3).

6 Test steps

The impact hammer shall strike the top center point of the back, front and side

protections from the outside, respectively.

Put the high chair on the ground. Place the test model (see 5.2) in the center of the seat

of the high chair. Apply a force of 200N in the point and direction most likely to cause

the high chair to fold.

7 Test report

The test report shall include at least the following information.
