家具UL认证过程中不可避免的会涉及到各种测试，我们主要说下升降桌UL认证/家具UL认证过程中会涉及到的各种UL认证相关测试。
 
本期咱们讲一下升降桌UL/家具UL认证的APPURTERNANCE STRENGTH AND STABILITY TEST认证测试细节。
 
测试针对范围：shelf, drawer, door, slide out, flaps, drop fronts需要通过UL认证的相关测试要求。
 
升降桌/家具UL测试治具
 
推拉力计，卷尺，称重计，秒表（设备需要按照UL认证的要求去校验）
 
升降桌UL/家具UL测试方法：
 
每一个shelf, drawer, door, slide out, flaps, drop fronts都需要承受一个向下的力，整个过程持续一分钟。力的大小是50磅（222N）。观察是否有损坏或者形变。细节如下：
 
1）With the appurtenances in the position that results in the maximum stress to the
appurtenance; and
 
2）At a point on the appurtenance which will produce the most severe results.
 
3）Door surfaces shall be manipulated and loaded by applying a 50-pound (22.68-kg) weight to
the top edge of the door at a point 3 inches (7.62 cm) in from the top edge. See Figure 38.4. A
door surface located above 30 inches (762 mm) from the floor but accessible to a child by
climbing up extendable appurtenances shall be subjected to the test
 
4）For multiple appurtenances each appurtenance is to be loaded with 50 pounds one at a
time.
 
判据：办公家具UL认证测试过程中产品不会有形变或者火灾的危害。
