(1)General conditions 一般条件
When a testing is conducted, and if there is no specific stipulation, the following conditions shall be complied with in principle. 当测试执行，若没有特别约定，需要遵照以下规定：
a.Testing instruments shall have enough performance and precision capable of judging the
conformance to the criteria. 测试仪器要有足够的性能和判断的精确能力，保证与标准
一致。
b.Measured values shall be read up to the point readable with the testing instruments. In this case,
an amount of deflection shall be read up to 0.01 mm.测试仪器的测量值可以具体读取，也
就是说变位度能读到0.01MM.
c.When calculating shear strengths or the like, one tenth (1/10) of least place of criteria value shall
be round off and obtain up to the least place of criteria value.
当计算变切强度或类似,标准值的最小地置的1/10将被完成,并且获取标准值的最小位置.
d.Chemicals used in testing shall be the special class stipulated in Japan Industrial Standard
(hereinafter referred to as “JIS”) (except those which are not stipulated in JIS).
在测试中使用的化学品要使用日本工业标准规定的特别等级(以下称JIS )(不在JIS规定的除外)
e.“About “means within ±10% of designated value and “Taking samples measured accurately”
means measuring up to a unit of 0.001 g. “大约”的意思是指定值的±10%之内, “获取样品
测量精确度”意思为测量至0.001G的单位.
f.Processing time duration in each test shall be within –0 minute and +5 minutes of designated
time duration. 每一个测试的加工测试时间应在指定的–0分钟至+5分钟的时间内.
g.The bending stiffness test, bending test and panel shear test shall be conducted in a condition of
a temperature of 20±2°C and a relative humidity of 65±5°C (hereinafter referred to as “related
temperature and humidity”) and using test pieces which are conditioned until their masses are
constant (referring to a condition that the difference of mass measured at an interval of 24 hours
is not more than 0.1%). In this case, if it is difficult to conduct a testing in a related temperature
and humidity condition, after conditioning of test pieces, promptly conduct the testing.
弯曲硬度测试,弯曲测试, 面板修切测试要在f20±2°C的温度和65±5°C温度的条件
下进行,(以下称”有关的温度和温度”),并且使用的测试样要适应于这种条件直到大
多数达到恒量(大量的差异测量间隔24小时的条件下不能多于0.1%) .这样,如果在
相关的温度和湿度实行测试困难,测试样条件作用后,尽快实行测试.
Further, if it is difficult to prepare a relative temperature and humidity condition due to some
constraints of facilities or if it takes a very long time to attain a constant mass in the relative
temperature and humidity condition due to some reasons in production, a testing may be conducted not in the relative temperature and humidity condition.
此外,如果由于设备的约束来准备相关的温湿度相当困难,或如果由于在生产中的某些原因在相关的温湿度条件下需要很长的时间才能达到恒量质量,测试可能不在这种相应的温度和湿度条件下进行.
However, in this case, judging from the relation between test results and moisture content of test pieces and so forth, it shall be appropriately estimated that the Young’s modulus of bending and bending strength in the relative temperature and humidity surely clear the criteria values.
然而,既然这样, 判断测试结果和测试样含水量之间的关系等等,在相对的温度和湿度清楚明了的标准值下，弯曲的YOUNG’S 系数和弯曲伸系数会适当地估算出来。
(2)Continuous boiling test, cyclic steaming test, vacuum pressure test, cyclic boiling test, steaming
treatment test or hot and cold water immersion test 持续的煮沸测试，循环蒸汽测试，真空压力测试，循环煮沸测试，蒸汽处理测试或冷热水浸泡测试。
a.Preparation of test piece 测试样的准备
Test pieces shall be prepared by the following methods from each sheet of sample plywood.
每一张样品胶合板的测试样将按以下方法准备：
(a)As for 3-ply plywood, 4 test pieces shall be prepared from each sheet of sample plywood in
such shapes as are shown in Fig. 1, a, A (Shape B shall be applied to plywood which has
shown a failure of face veneer during the test using test pieces of Shape A). In this case,
as to each sheet of sample plywood saw cuts shall be made so as to get the number of
test pieces half by half that have the lathe check of core veneer in the closed direction and
in the open direction against the loading direction.
对于3层的胶合板，从每一张胶合板中需准备4块测试样，形状如图1，a, 用A那样。（B形状适用不合格面板的胶合板，在测试中使用形状A进行测试）。
这样，对于每一张样品胶合板锯切变成一半一半的测试数量，以便在相反的载
重方向对闭合式和敞开式的芯板进行车床检查。
(b)As to 5-ply plywood, test pieces shall be prepared in such shapes as are shown in Fig. 1, b
in the same manner as in (a) above and saw cuts shall be made to make it possible to test
every one set of two glue lines (except parallel layers) of sample plywood. Moreover, as to
all the glue lines (except parallel layers) two test pieces of closed type and two test pieces
of open type respectively shall be used to conduct the test. In this case, veneer layers
unnecessary for the test may be stripped off. As to the plywood other than 5-ply plywood
(except those specified in (a) above), the same procedure shall be applied. Still more, if
plywood has parallel layers, as to each parallel layer, prepare more than two test pieces
which have parallel layers.
对于5层的胶合板，准备的测试样如图1，b如以上a的方式一样。测试样
板将锯切，尽可能测试样品胶合板的两面胶水线（平行层除外）上的每个部
分，而且，对于所有的胶水线（平行层除外）密封型的两个测试样和敞开式
