KIND OF TESTING
2
Determination of dimension of panels
- The dimension of panels testing
- The measuring of thickness
SNI (Indonesian Standard)
3
- The thickness, width, length and
squareness
- apply on each corners (4 points)
- The accuracy is not less than 0,05 mm
- Squareness
2.
Sampling and test pieces
- Sampling
MS (Malaysian Standard)

- The thickness, width, length, squareness,
flatness and edge straightness
- apply on 8 points (4 points at the corners
and 4 points at the middle of each edges)
- The accuracy is not less than 0,1 mm
- It's measured at the distance of 1000 mm
from the corner of the panel, with the
maximum deviation is 0,5 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
- It's measured at the distance of (1000 ± 1) mm
from the corner of the panel, with the
maximum deviation is 0,2 mm.
- The determination of samplings are
differed. There are sampling for
visual testing and sampling for
laboratory testing
- Both the number of panels (n) and
the number of test pieces (m)
are determined by the number of
all panels that will be tested (lot)
- 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
- Sampling determination is determined by
the kind of testing (MS 1787: Part 2: 2005
table 1).
- There're not determined by the number of
sample panels (n). There are not clear
- The number of test pieces are based
on the characteristic of panels that will be tested
