确定只是一块至少13厚的木板？ 会飞的鸭子 发表于 2017-3-8 21:01 static/image/common/back.gif
确定只是一块至少13厚的木板？
我公司一堆这个跌落木板，说全就是还要两块19mm厚的夹板，楼主没有说这个问题

如果我还是害死人，你早就死了。
楼主提到几块板子，怎么构成了吗？他问的是硬度。是不是像下面这样就全了？
4.2.6 Drop test
The following equipment is subjected to a drop test:
– HAND-HELD EQUIPMENT;
– DIRECT PLUG-IN EQUIPMENT;
– TRANSPORTABLE EQUIPMENT;
– desk-top equipment having a mass of 5 kg or less that is intended for use with any
one of the following:
• a cord-connected telephone handset, or
• another cord-connected hand-held accessory with an acoustic function, or
• a headset;
– MOVABLE EQUIPMENT requiring lifting or handling by the USER as part of its intended use.
NOTE An example of such equipment is a paper shredder that rests on a waste container, requiring its removal to empty the container.
To determine compliance, a sample of the complete equipment is subjected to three impacts
that result from being dropped onto a horizontal surface in positions likely to produce the most
adverse results.
The height of the drop shall be:
– 750 mm ± 10 mm for desk-top equipment as described above;
– 750 mm ± 10 mm for MOVABLE EQUIPMENT as described above;
– 1 000 mm ± 10 mm for HAND-HELD EQUIPMENT, DIRECT PLUG-IN EQUIPMENT and
TRANSPORTABLE EQUIPMENT.
The horizontal surface consists of hardwood at least 13 mm thick, mounted on two layers of
plywood each 19 mm to 20 mm thick, all supported on a concrete or equivalent non-resilient
floor
Compliance criteria are in 4.2.1.
:(准确来说，这种跌落试验木板是需要1层硬木加上2层胶合板结合而成的复合木板；
具体要求详见该认证标准章节描述，例如如下要求前者为IEC 60950-1:2006 + A2:2013 Clause 4.2.6，后者为IEC 60065:2014 Clause 12.1.5：
13.0 mm ± 0.1 mm； Layer 1 (第一层)- Hardwood (硬木板)
19.5 mm ± 0.5 mm； Layer 2 (第二层)- Plywood (胶合板)； And 18.0 mm ± 2.0 mm
19.5 mm ± 0.5 mm； Layer 3 (第三层)- Plywood (胶合板)； And 18.0 mm ± 2.0 mm
附上实验室针对此跌落木板的验收要求供参考，看是否能对大家有一些帮助。 硬度没有听说过有要求。。。。 rick.xiao 发表于 2017-3-9 09:20 static/image/common/back.gif

图文并茂，清楚了。
