Definition
定义

SLVL is lumber for general use composed of laminated veneer sheets that are
peeled off by rotary lathe or slicer and glued together with their grains nearly
parallel (in the case of a veneer sheet used as its grain is at a right angle with
that
of
the
adjoining
outer
most
veneer,
exclude
the
veneer
sheet
concerned
and other sheets than the above shall be used with their grains nearly parallel
to one another) and is used mainly as a load-bearing member of construction.
SLVL
是一种由镟板机或切片机剥离的页状层积单板胶合在一 起制成的具
有接近平行纹理的板材，
（在中间的一张单板的纹理是跟它外面的绝大多

除了这张，

其他的单板的纹理应该是互相平行的）

a.

Preparation of test pieces
试样的准备



Two square test pieces with a side of 75mm shall be prepared from each sample lumber (if the
width of sample lumber is less than 75mm, rectangular test piece with the said width and 75mm in
length shall be prepared).

从每个样品板上取
2
块边长为
75
毫米的正方形试样，
（如果样品板的宽度不足
75
毫米，
那
么试样 可以为长方形，其长度为
75
毫米而宽度为样品板的宽度。

b.

Methods of testing
测试方法



Test pieces, after being immersed in water of room temperature for 24 hours at a temperature of
60±
3
℃
with good ventilation.



把两片测试块在室温下浸泡
24
小时以后放在
60±< br>3
℃
的环境中并保持良好通风。

c.

Standard requirements for test pieces
测试件合格需要达到的标准



Ratio of delamination on 4 sides of test pieces shall not be more than 10% in length and the
length of delamination on the same glue line (except the delamination less than 3 mm in length, so
to be understood hereinafter) shall not be more than 1/3 of the length of the said glue line.
测试件四个 侧面的剥离率在长度上不得超过
10%
并且同一胶合层的剥离长度不得有超过
1/3< br>胶合层长度的情况存在。

Note: Ratio of delamination shall be calculated by the following equation.
注：剥离率应用以下公式计算。























Total length of delamination on 4 sides
Ratio of delamination = ----------------------------------- ------------------×
