3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 28202-
2020 as well as the followings apply.
3.1 shear and squeeze point
A gap that could cause injury to body parts when two parts within the accessible area
move relative to each other (closing, opening or folding).
3.2 bunk bed
Household and non-household bedding products that have one or more layers of bed
surfaces with the upper surface not less than 600 mm above the ground, a width not
greater than 1200 mm, and a length not less than 1400 mm.
NOTE. It does not include special bedding products for prisons, firefighting, military, etc.
[Source. GB/T 28202-2020, 3.41, modified]
3.3 safety barrier
A component that prevents a user from falling from the upper bunk bed of a bunk bed
(3.2).
4 Technical requirements
4.1 General structural safety
4.1.1 Basic structural safety
4.1.1.1 In normal use, all accessible edges and corners shall be rounded, chamfered,
sanded or protected in other appropriate ways. The rounding radius shall not be less
than 0.5 mm.
NOTE 1.The edge of the seat and the area within 120 mm inward from any other edge (seat back,
armrests and seat bottom surface) are generally considered to be areas that are easily accessible by
fingers.
NOTE 2.Any part of the table top, the bottom of the table top and any edge below the table top that
is less than 500mm away would normally be contacted by the knees and/or arms.
4.1.1.2 The connection between fixed parts shall be firm and not loose. There shall be
no missing parts, through nails or missing nails.
4.1.1.3 During normal use, the surfaces of other parts shall be free of sharp edges and
sharp angles.
4.1.1.4 Vertically movable parts shall not move on their own at any position 50 mm
above the closing point.
4.1.1.5 Push-pull components shall be equipped with anti-drop devices or warning signs.
The font size of the signs shall be no smaller than 5-point boldface.
4.1.2.3 Shear and squeeze points during use
4.1.2.3.1 Under the intended conditions of use, there shall be no accessible shear or
squeeze points.
4.1.2.3.2 Normal movement and operation (for example, attempting to move the chair
by lifting the seat or adjusting the backrest) shall not result in shear and squeeze points
that could cause injury.
4.1.2.3.3 The contact gap under force in normal use is tested using a hemispherical
finger probe (as shown in Figure 1). The gap shall be less than 7 mm or not less than
18 mm.
4.1.2.3.4 The process for determining shear and squeeze points shall be carried out in
accordance with the provisions of Annex A.
4.1.3 Holes and gaps
4.1.3.1 For holes and gaps with a depth exceeding 10 mm on rigid parts within the
product accessible area, the diameter or gap shall not be passed by a hemispherical
finger probe with a diameter of 7 mm (as shown in Figure 1) with a force of 30 N, or
can be passed by a hemispherical finger probe with a diameter of 12 mm (as shown in
Figure 1) without applying any force.
4.1.3.2 Pipe openings that do not comply with 4.1.3.1 shall be sealed.
4.1.3.3 The adjacent blocking parts of the head and foot of the bed and the safety barrier
shall be tested in accordance with 6.3 of GB/T 24430-2023.The net space gap between
adjacent blocking parts in the same direction shall not be greater than 75 mm and not
less than 60 mm.
