British Standards Institution (BSI) has
recently published the new edition ofBS 4875-1:2007

for the safety requirements for strength
and durability of domestic seating. This new
edition came into effect on 31 October, 2007
and together withBS EN 15373:2007(see STR
Furniture News #QA0042007 published in
October 2007),it supersedes BS 4875-1:2001,
which is withdrawn.

 The major change inBS
4875-1:2007is to specify
the strength and durability
requirements for domestic
seating only, while for nondomestic

(or contract)
seating, the requirements
are to be covered by

BS EN15373:2007.

 Similar to the previous edition, the performance
requirements are verified by tests which reproduce
normal use and common types of misuse to which
seating can be subjected. Five test levels(Table1)

are given, corresponding to the variations in
severity of end-use to be expected for various
types of seating. Samples are tested for applicable
test clauses in accordance with

BS EN 1728:2001
and with Annexes B & C ofBS 4875-1:2007, in
which have included static tests, fatigue tests,
impact tests, drop tests and assessment for
flexibility.

 早前类似的版本，通过反复正常使用及常见类型的滥
用所确定的座椅的测试来验证性能要求。对应不同类
型座椅所预期的最终用途的强度变化，给出五个测试
水平（表1）。样品测试适用的条款是根据

BS EN1728: 2001及BS 4875-1:2007附录 B & C，包括
静压测试、疲劳度测试、冲击测试、跌落测试及挠
度的评估。
