Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2020
“Directives for standardization - Part 1.Rules for the structure and drafting of
standardizing documents”.
This Standard replaces GB/T 22793.2-2008 “Furniture - Children’s high chair - Part 2.
Test methods”. Compared with GB/T 22793.2-2008, the main technical changes in this
Standard are as follows.
- Change the normative references. Use GB/T 531.1, GB/T 531.2 and GB/T 2411 to
separately replace ISO 2812-2, ISO 4628-3 and ISO 554;
- Change the provisions on test environment temperature and humidity (see 4.1 of
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,
5.10 of Edition 2008);
- Add the determination method for side protection (see 6.11 of this Edition).
This Standard is modified by adopting ISO 9221-2.2015 “Furniture - Children's high
chairs - Part 2.Test methods”.
Compared with ISO 9221-2.2015, this Standard made the following structural
adjustments.
- 5.9 and 5.10 correspond to 5.10 and 5.11 in ISO 9221-2.2015; 5.11~5.14
correspond to 5.13~5.16 in ISO 9221-2.2015; 5.15 corresponds to 5.9 in ISO
9221-2.2015; 5.16 corresponds to 5.12 in ISO 9221-2.2015;
- 6.7 corresponds to 6.7, 6.8 and 6.9 in ISO 9221-2.2015; 6.7.1 corresponds to 6.7 in
ISO 9221-2.2015; 6.7.2 corresponds to 6.8 in ISO 9221-2.2015; 6.7.3
corresponds to 6.9 in ISO 9221-2.2015; 6.8~6.16 correspond to 6.10~6.18 in ISO
9221-2.2015.
The technical differences between this document and ISO 9221-2.2015 and their
reasons are as follows.
- Delete the terms and definitions. They are defined in high chair requirements;
- Change the test equipment for openings (see 5.15 of this Edition, 5.9 of ISO 9221-
2.2015). Simulate children's fingers being trapped;
- Add part of the determination of material and appearance structure (see 6.1 of this
Edition), product material and appearance related safety;
- Change the test methods for small parts (see 6.5 of this Edition, 6.5 of ISO 9221-
2.2015). Small parts may be disassembled by twisting;
- Change the test methods for openings (see 6.6 of this Edition, 6.6 of ISO 9221-
2.2015). The following editorial changes have been made to this document.
- To harmonize with the existing standards, the name of the standard is changed to
“Test method for safety performance of children's high chairs”.

3 Terms and definitions
There are no terms and definitions that need to be defined in this document.
4 General test conditions

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.
