- Part 7 . Stability of tables
1 Scope
This Part of GB/T 10357 specifies the test method of loading stability of tables.
This Part applies to the tables which have no fixed connection with ground,
buildings, and furniture etc.
2 General test conditions
2.1 Specimen
Specimens shall be finished product, all connections and fasteners shall be
securely mounted in accordance with using state before testing.
Specimen shall be tested at the most unstable edge of the table, if the edge is
not obvious, it shall be determined by experiment.
For specimen with movable table board, it shall be tested under the most
unstable using state. When movable table board has multiple connectivity
methods, it shall choose the most unstable connection method. If the table is
installed with drawer, the drawer shall be closed and shall not be loaded when
testing.
2.2 Test tolerance
Except that there are other specific provisions, measurement error of all
loading force is ± 5%; measurement error of all dimensions is ± 1 mm; error of
withstanding position shall be controlled within ± 2 mm.
3 Test facility
3.1 Loading equipment
The equipment that can be ensured to be loaded correctly according to the
provisions of this Part can be used. Loading equipment can provide a vertical
or horizontal loading force, this force may be fixed or gradually increasing.
Appendix A
(Normative)
Minimum loading force of stability of typical tables
Minimum loading force of stability of typical tables shall accord with the
provisions of Table A.1.
Table A.1 Minimum loading force of stability of typical tables
Typical tables
Vertical loading stability
Vertical and horizontal
loading stability
Four-leg tables 600 40
Writing tables 600 40
Single-leg tables 200 30
Classroom tables 600 20
Folding tables 200 30
Note. Single-leg tables refer to those tables of which the ratio of the area formed by the
connection of its support points AND the area of its tabletop is less than 65%.
