Foreword
This Standard replaces JG/T 3029-1995 Light longish panels for internal
partitions in residence.
This revision extends the scope of application of light weight panels for partition
walls used in buildings; it adds the terms, revises the technical requirements
and test methods for light weight panels. Compared with JG/T 3029-1995, the
main changes are as follows.
1 Deleted “50 mm thick plate” in specifications;
2 Deleted control indexes of “out heed and inter orifice, mortise and rabbet”
in size deviation; added control index of “wall thickness”;
3 Modified “areal density”, “air weighted sound reduction index”, “bending
failure load”, “impact resistance” and “drying shrinkage value” in physical
and mechanical properties; added “compressive strength”, “moisture
content”, “softening coefficient”, and “heat transfer coefficient”; deleted
“combustion performance”;
4 Specified radionuclide limit index of light weight panels;
5 Modified stipulated items of product factory inspection.
This Standard was proposed by Research Institute of Standards and Norms of
Ministry of Construction.
This Standard shall be under the jurisdiction of National Technical Committee
on Building Products and Components of Ministry of Construction.

Light weight panels for partition walls used in
buildings
1 Scope
This Standard specifies the terms, classification, requirements, test methods,
inspection rules, marks, transport and storage of light weight panels for partition
walls used in buildings (hereinafter referred to as “light weight panels”).
This Standard is applicable to light weight panels for non-load bearing partition
walls used in general buildings.

3 Terms and definitions
The following terms and definitions apply to this Standard.
3.1 lightweight panel
Prefabricated panel made by lightweight materials or in lightweight construction,
and used for non-load bearing partition walls, of which areal density is not
greater than the value stipulated in this Standard, and length-width ratio is not
less than 2.5.
3.2 hollow cores panel
Prefabricated panel of which a number of through-holes along the longitudinal
direction of plates.
3.3 solid panel
Prefabricated panel, without holes, that is made by materials of same kind.
3.4 composite sandwich panel
Prefabricated panel composed by two and more materials of different functions,
or composed by panel (casting surface layer) and core layer material.
3.5 out heed and inter orifice
General term for mortise, rabbet and joint groove set on both sides of panel.
4 Classification
4.1 Classification and code
According to sectional configuration, lightweight panel is divided into hollow
cores panel, solid panel and composite sandwich panel; OR ordinary panel,
door frame panel and irregular panel, according to component type of panel.
The classification and code of lightweight panel are shown in Table 1.

4.2 Product type
The lightweight panel can be made as hollow cores, sandwich and composite
sandwich type. It shall use different out heed and inter orifice, and opening but
it shall all comply with the provisions of Article 3.1 and Clause 5 of this Standard.
mm × 30 mm
6 Wall thickness b / mm ≥ 12
NOTE Defects in 3, 4, and 5 that are lower than the limits are negligible while defects that
are higher than the limits are unqualified.
a This inspection is for composite sandwich panel.
b Wall thickness shall be inspected for hollow cores panel.
5.3 Size deviation
Panel size tolerance shall comply with the provisions in Table 3.
Table 3 Size tolerance unit. mm
No. Item Size tolerance
1 Length ± 5
2 Width ± 2
3 Thickness ± 1
4 Panel surface levelling ≤ 2
5 Diagonal difference ≤ 6
6 Lateral bending L / 1000
5.4 Physical and mechanical properties
Corresponding use area, physical and mechanical properties indexes stipulated
by different moisture content of panel shall comply with the provisions in Table
4 and Table 5.
Table 4 Corresponding use area stipulated by different moisture
content of panel
Moisture content % ≤ 12 ≤ 10 ≤ 8
Use area Moist Medium Dry
NOTE
Moist area refers to the area where annual average relative humidity is greater than 75%;
Medium area refers to the area where annual average relative humidity is 50% ~ 70%;
Dry area refers to the area where annual average relative humidity is less than 50%.
be equal to panel width.
6.4.2.5 Place it for 2 min after the first four grades are applied. When the fifth
grade of load is applied to 1.5 times panel weight, place it for 5 min. If it
continues to applying load, circulate this grade loading mode till it breaks and
cracks.
6.4.2.6 Record the total load from the first grade of load to the fifth grade (or
the grade before it breaks and cracks) as test results.
6.4.2.7 The test results only apply to panels of which the length is within the
size scope of panels for test.
