GB/T 15104-2021Decorative veneered wood-based panel (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 15104-2006 "Decorative Veneer Veneer Artificial Panels", compared with GB/T 15104-2006, except for editorial revisions In addition, the main technical changes are as follows.

---Delete common wood species for veneers (see 5.1.2.2 of the.2006 edition);

--- Deleted the "decorative" inspection items in the appearance requirements (see Table 3 of the.2006 edition);

---Change the content of the note in Table 3, and change it to the judgment of appearance defects under special circumstances.

When other defects are used as special decorative requirements, they can not be regarded as appearance defects (see Table 3,.2006 edition of Table 3);

---The lower limit of moisture content has been changed, and the lower limit of moisture content of decorative veneer veneer plywood and decorative veneer veneer blockboard has been changed from 6.0% The lower limit of moisture content of decorative veneer particleboard and decorative veneer medium-density fiberboard is changed from 4.0% to 5.0%. 3.0% (see Table 4, Table 4 of the.2006 edition);

---Changed the surface resistance to cold and heat cycle performance requirements, added "bulge", deleted "boring, and dimensionally stable" (see Table 4, 2006 version of the Table 4);

---The physical and mechanical performance requirements of decorative veneer veneer wood-based panels have been added. In addition to the physical and chemical properties in Table 4, the veneer man-made panels are also specified The other performance index values of the board shall not be lower than the physical and mechanical performance requirements of each type of board of the corresponding base material (see 5.4.2);

---Delete the "Limit of formaldehyde emission for decorative veneer veneer wood-based panels", and the amount of formaldehyde emission shall be implemented in accordance with the provisions of GB 18580-2017.

The result is accurate to 0.001mg/m³ (see Table 4, 6.3.6, and Table 5, 6.3.6 of the 2006 edition);

---Changed the surface bonding strength, immersion and peeling performance, light fastness, surface resistance to cold and heat cycle performance methods, adopt The method specified in GB/T 17657-2013 (see 6.3.3, 6.3.4, 6.3.5, 6.3.7, 6.3.3, 6.3.4, 6.3.5, 6.3.7);

---Changed the test method of the heat and cold cycle when the thickness of the test piece is greater than 8mm, and canceled the metal frame for fixing the test piece (see 6.3.5, 2006 edition) Of 6.3.5);

--- Changed Figure 1 "Schematic diagram of sample production (1)" and Figure 2 "Schematic diagram of sample production (2)" (see Figure 1 and Figure 2, 2006 version of the Figure 1 and Figure 2);

---Deleted the method for determining the color fastness to light in Appendix A (see Appendix A of the 2006 edition), and retains the "Grade Evaluation of Color Fastness to Light" Table" (see Appendix A).
