1. Determination of dimension of panels
- The dimension of panels testing - The thickness, width, length and
- The thickness, width, length, squareness, squareness
flatness and edge straightness
- The measuring of thickness - apply on each corners 4 points
- apply on 8 points 4 points at the corners and 4 points at the middle of each edges
- The accuracy is not less than 0,05 mm - The accuracy is not less than 0,1 mm
- Squareness - Its measured at the distance of 1000 mm
- Its measured at the distance of 1000 ± 1 mm from the corner of the panel, with the
from the corner of the panel, with the maximum deviation is 0,5 mm.
maximum deviation is 0,2 mm. Especially for plywood, the squareness is
measured as the difference of the two diagonals length of the panel, with maximum
tolerance is 3 mm
2. Sampling and test pieces
- Sampling - The determination of samplings are
- Sampling determination is determined by differed. There are sampling for
the kind of testing MS 1787: Part 2: 2005 visual testing and sampling for
table 1. laboratory testing
- Both the number of panels n and - Therere not determined by the number of
the number of test pieces m sample panels n. There are not clear
are determined by the number of - The number of test pieces are based
all panels that will be tested lot on the characteristic of panels that will be tested
- For plywood: the test pieces must represent by all the part of panel
For particle board and fibreboard: the number of sampling n is not clear

3. Moisture content
- The dimension of test pieces - The minimum number of test pieces is 1 pieces
- The minimum number of test pieces is 4 pieces - 100 mm x 100 mm
- The dimension is not specified but the minimum weight of the test piece is 20 g

4. The determination of density
- The dimension of test pieces the minimum number of test pieces is 1 piece
- the minimum number of test pieces is 6 pieces - 100 mm x 100 mm 1 piece sample for
- 50 mm x 50 mm both density and moisture content
- The thickness is measured at 25 mm from - The thickness is measured at a point of inter-
each corner 4 point section of the diagonals
- The length and width are measured at along - The length and width are measured at two lines,
two lines parallel to and at a distance of 25 mm parallel to the edges, along lines which pass
from the edges through the center of opposite edges
- The test pieces are conditioned before testing, at the humidity 65 ± 5 and temperature
20 ± 2°C
5. The thickness swelling
