跌落试验指导书
一、目的 test purpose
按规定条件将
手持电动工具跌向刚性地面,检验工具在误跌时,电气、机械、功能的可靠性。
Drop hand-held tool to rigid floor on test condition, then check product’s electrical and mechanical dependability
二、适用范围 application range
手持式MPP电动工具 hand-held tool
三、参考标准 reference
CSA标准,UL 标准,EN50144-1.标准
CSA standard, UL standard and EN50144-1 standard
四、试验条件/设备 test condition/equipment
电参数测量仪、耐压仪,漏电流测量仪 ,测速计,混泥土地面, 三台样机
parameter instrument / hi-pot/ speed-test /concrete floor
五、试验步骤/要点 test process
测试条件:温度20~25℃,混凝土地面; condition: temperature : 20-25℃// concrete floor
1.实验前测量空载参数及泄漏电流并做记录; before test ,test for current /power/and leak current
2.选择样品最薄弱点(可先进行摸底实验,找出最薄弱点),每个样品最少选择6个不同位置来选择跌落点;工具从3英尺高处自由跌落到混凝土平面上,每个样品的最薄弱点,跌落1次; select the most weakness of tool (the operator can try dropping to get which are weakness), every tool must drop 6 side. Drop the tool from 3Ft freely to concrete floor, make sure every weakness drop one time.
3.若第一台失效,换第二台在同一点跌落,若通过,则实验通过;若失效,换第三台在同一位置继续跌落; if the first one fail, drop the second on the same side ;if it pass the test is OK. If the second fail , drop the third on the same side as the side of second failure side.
4.每次跌落后要测量空载参数并记录;
test tool’s parameter (such as current /power ) and record after drop.
5.经过所有跌落后,测试泄漏电流检查并记录;check leak current after finished all drop .
6. 经过所有
跌落实验后,工具应能承受相应的耐电压实验,而不发生 击穿或闪络;
Do hi-pot test , check if the tools can pass.
六、判 断标准 judgement standard
样品经过
跌落实验后,电气及机械性能安全,不能丧失功能即为合格;(“功能”是指使用者所期望的工具应具有的合适的使用能力。技师如果能够相当简单的修理和改正被损坏的部分,那么这些影响功能的损坏是可以允许的。如果工具的精度严重超过了范围,或者需要控制工具的手柄断裂,有元件或电线暴露于使用者,那么实验认为失败。轻微的凹陷和裂纹,以及不被使用者注意的精度变化是可以接受的.) If tool’s function is normal and no electrical and mechanical danger after finished test , it pass the test . (notes: its function mean proper use ability. If parts or metal are bare(can be dangerous), it fail in the test . light distortion or crack can be permitted)
七、相关记录 test record
1.每次跌落前后的空载参数记录; record parameter
2.跌落测试后的泄漏电流和介电强度检查记录; record leak current after drop
3.跌落中出现的问题记录; record failure phenomena
4.最后结果及分析记录。 Test result and analysis record
