SAFEGUARDS | Hardlines NO. 161/18
EN 1335-2: 2018 – Office furniture – office work seat – Part 2: Safety requirement was published in November 2018 and supersedes both the EN 1335-2:2009 and EN 1335-3:2009 standards.
The updated standard introduces the most recent version of test method standards EN 1728:2012 and EN 1022:2018, which is why it supersedes its predecessor – EN 1335-3:2009.
The main impact of the modification concerns stability. Key modifications between EN 1022 and then EN 1335-3 are:
- EN 1335-3 required the forward stability test to be performed at those points most likely to result in overturning, now EN 1022:2018 requires the vertical force to be applied to the centerline of the seat
- EN 1335-3 has a front edge stability test which has been replaced by a simpler corner stability test
- Sideways overturning for a seat without armrest testing requires a vertical force to be applied at those points most likely to result overturning, but the new EN 1022:2018 requires the vertical force to be applied on the transverse plane of the seat, which means the plan that pass by point A
- Regarding the sideways overturning for other seating, EN 1022:2018 considers more configurations and is more precise regarding the test method
- Attention should be drawn to the wording regarding testing reclining positions, the disc test under the wording for tilting seats is still applicable for seats with adjustable positions
- For the rearward overturning for seat without backrest inclination and for seat with an adjustable backrest that can be locked on, the previous EN 1335-2 the horizontal force was 192N, now a formula is applicable depending of the height of the loaded seat above the floor
Regarding strength and durability, the main modifications are the following:
- Shear and squeeze point requirements are aligned on other standard requirements
- Rolling resistance testing has to be carried out after stability and strength durability testing
- Strength parameters, such as force and cycle remain the same
- The different between test method in EN 1728:2012 and EN 1335-3:2009 shall remain the same
Office furniture falls under the GPSD which requires products to be confirmed compliant with the most update version of the standard. The standard is normally applicable immediately after publication.
Each country has until May 2019 to officially publish the standard, this period may be considered a transition period.
