Foreword
This Standard is a revision to GB/T 15102-1994 Surface decorated wood-based panels with paper impregnated thermosetting resins.
The indicators and inspection methods of light fastness in this Standard non- equivalently use Pr EN 14323-2001 Wood-based panels - Melamine faced
panels for interior uses - Characteristics and test methods.
Compared with GB/T 15102-1994, the main technical changes in this Standard are as follows.
- added classification categories;
- improved appearance quality requirements for each grade of products;
- adjusted width specifications;
- adjusted sample preparation methods;
- modified scratch test method;
- added formaldehyde release limit indicators and test methods;
- added light fastness indicators and test methods.
Since the date of implementation of this Standard, it replaces GB/T 15102-1994. Annex A of this Standard is normative.
This Standard was proposed by China's State Forestry Administration.
This Standard shall be under the jurisdiction of National Panel Standardization Technical Committee.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 surface decorated wood-based panels with paper impregnated
thermosetting resins
the decorative sheet that uses particleboard, fiberboard and other wood-based as substrate, impregnated thermosetting resins paper as finishing material 3.2 color unmatching
the color of a pattern is visually different from the color of a given standard 3.3 misalignment between panel and impregnated paper
product panel out of paper caused by film paper and substrate misalignment, including decorative white paper printing, cracks
3.4 tearing of impregnated paper
product surface rupture marks due to partial fracture of film paper
3.5 frosting mark
white flower
opaque white piebald on product surface
3.6 water mark
also known as water stain, fog mark on product surface
3.7 porosity of surface
pinhole defects on product surface
3.8 spots, dirt and similar surface defects
dust in base paper, ink marks on printing, and decorative defects caused by impurities in the process
3.9 bare substrate spots due to defective surface covering
6.2.4 Inspection of verticality
In accordance with 5.1 in GB/T 19367.2-2003.
6.2.5 Measurement of edge straightness
In accordance with 5.2 in GB/T 19367.2-2003.
6.2.6 Inspection of warpage
Place the product on a level table with the concave surface facing up. Use fine steel tire to connect two opposite angles of panel. Measure the maximum chord length with steel ruler, to the nearest of 0.5 mm. The ratio of the maximum chord height to the diagonal length is the warpage, represented in percentage, to the nearest of 0.1%.
6.3 Physical and chemical properties test methods
6.3.1 Preparation and dimensions of test specimens and test pieces
6.3.1.1 The samples and test specimens shall be extracted from the products being stored for more than 24h after production.
6.3.1.2 Cut the sample of surface decorated wood-based panels with paper impregnated thermosetting resins into five test specimens as shown in Figure 5. Each test specimen shall be marked with number and ?€????€? on the right top. Specimens 1, 3. 5 are used to prepare ?€?number?€? test pieces, 2, 4 are for ?€?random?€? test pieces. See Table 5 for the size, quantity and number of test pieces. The prepared test pieces shall have straight edges; the adjacent two shall be at right angles. The specifications of number test pieces prepared from specimens 1, 3, 5 shall be in accordance with Figure 2. When it has defects on the specified test piece preparation position, it shall appropriately move the preparation position of test piece. When the panel thickness is greater than 25 mm, the test piece of static bending strength (size exceeding 550 mm) may be extracted randomly in the sample panel, maintain 3 pieces respectively for vertical and horizontal directions. The test pieces of other numbers shall maintain the original directions.
6.3.8.2 Instruments and tools
Carry out in accordance with 4.13.2 of GB/T 17657-1999.
