Discover one of the mechanical tests performed on school or community chairs: stability when placed on a table.
Objective of the test:
Ensure that the chair does not fall when placed on a table (e.g., cleaning the room).
Principle of the test:
The chair is placed on the front edge of the table top.
A 6.5 kg hammer is then positioned 40 cm from the table top.
The angle applied to the hammer is calculated to have a drop height of 31 cm
...to obtain an impact of 2 joules
The hammer must touch the chair only once. A total of 3 impacts are made.
The method used is standardized: NF EN 17292-2
A piece of furniture with the NF mark will withstand this particularly selective test: during and after the impacts, the chair must not fall.
