Study Notes
Sofa and Sofa-Bed Testing
- Rear stability test: numerous disks representing a person leaning back are placed along the backrest to ensure the chair does not tip over.
- Front stability test: loads representing a person sitting on the front edge are applied near the front of the seat pan to ensure the chair does not tip over.
- Leg strength tests: the chair must withstand a force for one minute in the horizontal direction at the front leg for the functional requirement and a greater force for the proof requirement.
Chair Testing
- Chairs are tested for safety, strength, and durability according to EN 12520:2015 for domestic use and EN 16139:2013 for non-domestic use.
- Tests simulate normal functional use and misuse, applying loads, forces, and velocities that might reasonably be expected to occur.
- The difference between chair testing for domestic use and visitor chairs testing lies in the applied load during static load tests and the cycles for durability tests.
Bed Testing
- Bed testing covers all types of fully erected domestic adult beds, including bed frame, bed base, mattress, and mattress pads.
- Beds are tested for safety, stability, strength, and durability according to EN 1725:1998.
- This standard does not include bunk bed testing.
Additional Testing
- Backrest strength test: the chair must withstand a force for one minute for the functional requirement and a greater force for the proof requirement.
- Drop test: the chair must withstand a weighted bag dropped into the chair for the functional requirement and a heavier bag for the proof requirement.
- Seating durability test: the chair must withstand a weighted bag set into the center of the seat pan for 100,000 cycles and again for 20,000 cycles each front corner.
