What is the main purpose of this standard?

To provide a uniform method for determining the stability of tables and trolleys to ensure they do not easily tip over in normal use.

What force is used to test the horizontal stability of a table?

A horizontal force of 20 N is applied outwards at the edge of the tabletop at the midpoint of the longest side (Clause 4.3).

How is a trolley's stability tested?

The trolley is loaded with its maximum specified weight, then tilted to an angle of 5 degrees. It must not overturn (Clause 6).

What is the difference in testing a 'large' versus a 'small' table?

A large table (top > 0.25 m²) is tested with a 750 N vertical load, while a small table (top ≤ 0.25 m²) is tested with a 350 N load (Clause 3.2).

This standard prescribes the methods for testing the stability of various types of tables and trolleys. It details procedures to apply vertical and horizontal forces to assess the furniture's resistance to overturning under simulated use conditions.

Practical Notes

Ensure the test surface is perfectly horizontal, rigid, and flat to ensure accurate and repeatable results.

Apply all test forces slowly and without shock to avoid dynamic effects influencing the static stability measurement.

The placement of stops to prevent sliding is critical; they must not be higher than 3 mm to avoid restraining the furniture from tilting.
