Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 3324-2008 “Wooden furniture - General technical

Standard, Clause 4 of the 2008 edition);
- MODIFY the main dimensions of tables, cabinets, chairs and stools, and
beds (see 5.1 of this Standard, 5.1 of the 2008 edition);
- DELETE the requirements for the moisture content of wood-based panels;
MODIFY the consistency of identification and the technical requirements
for wood-based panels (see 5.3 of this Standard, 5.3 of 2008 edition);
- DELETE the requirements for resistance to cigarette burns; MODIFY the
requirements for wearability of paint film; MODIFY the requirements for
resistance to liquids of flexible and rigid overlay; DELETE the requirements
for surface bonding strength; ADD the requirements for resistance to wet
heat of surface; MODIFY the requirements for corrosion resistance of metal
handles (see 5.5 of this Standard, 5.5 of the 2008 edition);
- MODIFY the technical requirements for tables, cabinets, chairs and stools
(see 5.7 of this Standard, 5.7 of the 2008 edition);
- ADD the requirements and test methods for structural safety (see 5.8.1 and
6.8 of this Standard);
- MODIFY the requirements and test methods for formaldehyde emission;
ADD the requirements and test methods for VOC limit; ADD the
requirements and test methods for decomposable aromatic amines in
leather and textile fabrics (see 5.8.2 and 6.9 of this Standard, 5.8 and 6.8
