BS 5459-2:2008 is concerned with the specification of performance requirements for the structural safety of office seating when used by persons weighing more than 110 kg, or when used for more than 8 hours a day.
BS 5459-2 specifies performance requirements and test methods for the structural safety and stability of office pedestal seating when used by persons weighing up to 150 kg, or when used for up to 24 hours a day, including chairs for use with tables and desks higher than those specified in BS EN 527-1.
It also specifies requirements and test methods for type-approval of bases, columns, seat actions, back stems and locking devices.
BS 5459-2 seeks to ensure that the seating will not become a danger or cause injury to users when it is used as office seating in a manner which is forseeable.
BS 5459-2 gives:
- Normative references
- Terms and definitions
- Requirements for durability, component durability, stability, safety
- Type approval of bases, columns, seat actions, back stems and locking devices
- Criteria for failure and safe failure
- Marking for complete chairs and for bases, columns, seat actions, back stems and locking devices.
An annexe containing test methods is also provided.
The tests specified in this standard do not ensure that structural failure will not eventually occur as a result of habitual misuse or after an excessively long period of service. An attempt has been made to ensure that as far as can be forseen, such service failures as may occur will not be a serious hazard to health.
