Foreword
GB/T 4897 Particleboard is divided into 7 parts.
— Part 1. General requirements for all board types;
— Part 2. Requirements for general purpose boards for use in dry conditions; — Part 3. Requirements for boards for interior fitments (including furniture) for use in dry conditions;
— Part 4. Requirements for load-bearing boards for use in dry conditions; — Part 5. Requirements for load-bearing boards for use in humid conditions; — Part 6. Requirements for heavy-duty load-bearing boards for use in dry conditions;
— Part 7. Requirements for heavy-duty load-bearing boards for use in humid conditions.
This Part is Part 2 of GB/T 4897 Particleboard.
This Part is not equivalent to European Standard EN 312-2.1997 Particleboard-Part 2. Requirements for general purpose boards for use in dry conditions. Except for adding the surface bonding strength and 2 h water-absorption thickness swelling rate, physiochemical performance indexes are the same as EN 312-2. Inspection item of size-change is not listed in this Part.
This Part replaces the corresponding part of GB/T 4897-1992 Particleboard. Compared with the previous standard (GB/T 4897-1992), the important technical change in this Standard is to divide the previous standard into 7 parts, in which, the “Requirements for load-bearing boards for use in humid conditions” and
“Requirements for heavy-duty load-bearing boards for use in humid conditions” are the newly-added contents. The requirements of physiochemical performance in this Part is lower than that in the previous standard.
This Part was proposed by State Forestry Administration.
This Part shall be under the jurisdiction of National Technical Committee 198 on Wood-based Panels Standardization of China.
Responsible drafting organizations of this Part. Research Institute of Wood Industry, Chinese Academy of Forestry.
Participating drafting organizations of this Part. Beijing Timber Mills, and Hebei Golden Sunbird Panel Co., Ltd.
Main drafters of this Part. Chen Shiying, Long Ling, Zheng Fengshan, and Zhang Zhanhao.
This Part was first-time released in February 1985, and first-time revised in August 1992. This is the second revision.
This Standard shall be interpreted by National Technical Committee on Wood-based Panels Standardization.
