JG/T 169-2005Light weight panels for partition walls used in buildings (English PDF)

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 & 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.
